Ezra Townsend Cresson
Ezra Townsend Cresson, also Ezra Townsend senior (18 June 1838, in Byberry – 19 April 1926, in Swarthmore) was an American entomologist who specialised in the Hymenoptera order of insects. He wrote ''Synopsis of the families and genera of the Hymenoptera of America, north of Mexico'' Philadelphia: Paul C. Stockhausen, Entomological printer (1887) and many other works. His son Ezra Townsend, Jr. (1876–1948) was also an entomologist but a specialist in Diptera. Cresson also documented many new species including ''Nomada texana ''Nomada texana'' is a species of bee native to the southern and western United States and other parts of North America (including Mexico Mexico (Spanish language, Spanish: México), officially the United Mexican States, is a List of sover ...''.

Monardella
''Monardella'' is a genus of approximately 40 species of annual and perennial plants native to western North America from British Columbia to northwestern Mexico. They are grown for their highly aromatic foliage, which in some species is used for herbal teas. The two-lipped, tubular flowers are formed in terminal clusters and are most usually red, pink, or purple. ''Monardella'' is a taxonomic patronym honoring the Spanish botanist Nicolás Monardes. Plants in this genus are commonly known as wildmints, coyote mints or monardellas. Systematics The genus comprises the following species. * '' Monardella antonina'' Hardham - California * ''Monardella arizonica'' Epling - Arizona * '' Monardella australis'' Abrams - southern California * '' Monardella beneolens'' Shevock, Ertter & Jokerst - southern California * '' Monardella boydii'' A.C.Sanders & Elvin - southern California * '' Monardella breweri'' A.Gray - California, Nevada, Arizona, Baja California * '' Monardella candicans'' ...

Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bumblebees
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. Species Description ''Rhododendron'' is a genus of shrubs and small to (rarely) large trees, the smallest species growing to t ...

Phacelia
''Phacelia'' (phacelia, scorpionweed, heliotrope) is a genus of about 200 species of annual or perennial herbaceous plants in the borage family, native to North and South America. California is particularly rich in species with over 90 recorded in the region. The genus is traditionally placed at family rank with the waterleafs ( Hydrophyllaceae) in the order Boraginales. The Angiosperm Phylogeny Group, recognizing that the traditional Boraginaceae and Hydrophyllaceae are paraphyletic with respect to each other, merges the latter into the former and considers the family basal in the Euasterids I clade. Other botanists continue to recognize the Hydrophyllaceae and Boraginales after analysing the secondary structure of the ITS1 genetic region rather than its sequence for these higher taxonomic levels. This placed ''Phacelia'' within the Hydrophyllaceae. Further molecular taxonomic analysis of the Boraginales has divided the Boraginales in two and placed ''Phacelia'' among the mo ...

Penstemon
''Penstemon'' , the beardtongues, is a large genus of roughly 250 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. Formerly placed in the family Scrophulariaceae by the Cronquist system, new genetic research has placed it in the vastly expanded family Plantaginaceae. They have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue. Most penstemons are deciduous or semi-evergreen perennials, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilobium
''Epilobium'' is a genus of flowering plants in the family Onagraceae, containing about 197 species. The genus has a worldwide distribution. It is most prevalent in the subarctic, temperate and subantarctic regions, whereas in the subtropics and tropics ''Epilobium'' species are restricted to the cool montane biomes, such as the New Guinea Highlands. The taxonomy of the genus has varied between different botanists, but the modern trend is to include the previously recognised genera ''Boisduvalia, Pyrogennema'' and ''Zauschneria'' within ''Epilobium''. ''Chamaenerion'', (previously ''Chamerion''), is considered distinct, however,Wagner & Hoch 009a,b/ref> according to Peter H. Raven, who has extensively studied the willowherbs and merges the other segregate genera into ''Epilobium''. Fringed willowherb (''Epilobium ciliatum'') is likely a cryptic species complex; apparently these plants also commonly hybridize with their congeners. Most species are known by the common name willow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ceanothus
''Ceanothus'' is a genus of about 50–60 species of Actinorhizal plant, nitrogen-fixing shrubs and small trees in the buckthorn family (Rhamnaceae). Common names for members of this genus are buckbrush, California lilac, soap bush, or just ceanothus. ''"Ceanothus"'' comes from grc, κεάνωθος (''keanōthos''), which was applied by Theophrastus (371–287 BC) to an Old World plant believed to be ''Cirsium arvense''. The genus is native to North America with the highest diversity on the western coast. Some species (e.g., ''Ceanothus americanus, C. americanus'') are restricted to the eastern United States and southeast Canada, and others (e.g., ''Ceanothus caeruleus, C. caeruleus'') extend as far south as Guatemala. Most are shrubs tall, but ''Ceanothus arboreus, C. arboreus'' and ''Ceanothus thyrsiflorus, C. thyrsiflorus'', both native to California, can be small multi-trunked trees up to tall. Taxonomy and etymology There are two subgenera within this genus: ''Ceanothus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
