Spironema (gastropod)
†''Spironema'' is a genus of extinct (Cretaceous) sea snails, marine gastropod mollusks in the family Naticidae, the moon snails.Siemers C. T. & King N. R. (1974). "Macroinvertebrate paleoecology of a transgressive marine sandstone, Cliff House Sandstone (Upper Cretaceous), Chaco Canyon, northwestern New Mexico". ''New Mexico Geol. Soc. Guidebook'', 25th Field Conf., Ghost Ranch (Central-Northern N.M.): 267-277PDF Description The American paleontologist Fielding Bradford Meek firstly defined this genus in 1864. He classified the genus in the family Littorinidae. He recognized two species '' Spironema bella'' and '' Spironema tenuilineata'' in 1864. These species were previously classified within the family Trochidae. Meek's diagnosis reads as follows: Species Species within the genus ''Spironema'' include: * '' Spironema bella'' (Conrad) - synonym: ''Tuba'' (?) ''bella'' Conrad, from Cretaceous of Alabama * '' Spironema tenuilineata'' (Meek & Hayden, 1856) - from Cretaceou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassytha
''Cassytha'' is a genus of some two dozen species of obligately parasitic vines in the family Lauraceae. Superficially, and in some aspects of their ecology, they closely resemble plants in the unrelated genus ''Cuscuta'', the dodders.Weber, J. Z. A TAXONOMIC REVISION OF CASSYTHA (LAURACEAE) IN AUSTRALIA. J. Adelaide Bot. Gard. 3(3): 187-262(1981JSTOR/ref> When fruit and flowers are absent in the field, the physical resemblance is so close that few people without technical training can discern the difference. In this respect and in their ecology the two genera present a spectacular example of convergent evolution.Nickrent, D. L. 2002. Phylogenetic Origins of Parasitic Plants. Chapter 3, pp. 29-56 In J. A. López-Sáez, P. Catalán and L. Sáez ds. Parasitic Plants of the Iberian Peninsula and Balearic Islands. Mundi-Prensa, Madrid. Nonetheless, Nickrent comments that "''Cassytha'' is uneqivocally assigned to Lauraceae based on (both) morphological and molecular data." In ...

Callisia
''Callisia'' is a genus of flowering plants in the spiderwort family, Commelinaceae. Members of the genus are commonly known as roselings. It is native to the Western Hemisphere from the southern United States to Argentina. The generic name is derived from the Greek word κάλλος (''kallos''), meaning "beauty." Some members of ''Callisia'' may cause allergic reactions in pets (especially cats and dogs), characterised by red, itchy skin. Notable culprits are ''C. fragrans'' (inch plant) and ''C. repens'' (turtle vine). Species ''Callisia'' includes the following species: * '' Callisia ciliata'' Kunth – Panama, Colombia * '' Callisia cordifolia'' ( Sw.) E.S.Anderson & Woodson – Florida Roseling – Central America, tropical Mexico, Cuba, Jamaica, Venezuela, Colombia, Ecuador, Peru, Florida, Georgia * '' Callisia filiformis'' (M.Martens & Galeotti) D.R.Hunt – central + southern Mexico, Central America, Lesser Antilles, Venezuela, northeastern Brazil * '' Callisi ...

Clerodendrum
''Clerodendrum'' is a genus of flowering plants formerly placed in the family Verbenaceae, but now considered to belong to the Lamiaceae (mint) family. Its common names include glorybower, bagflower and bleeding-heart. It is currently classified in the subfamily Ajugoideae, being one of several genera transferred from Verbenaceae to Lamiaceae in the 1990s, based on phylogenetic analysis of morphological and molecular data. Estimates of the number of species in ''Clerodendrum'' vary widely, from about 150Yao-Wu Yuan, David J. Mabberley, Dorothy A. Steane, and Richard G. Olmstead. 2010.
