Jacaranda Subalpina
''Jacaranda subalpina'' is a species of flowering tree native to Brazil. Description ''Jacaranda subalpina'' grows to between to tall. The leaves are 25 to 45 cm in length and bipinnate The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular o ..., having between 11 and 23 pinnae and 17 to 23 leaflets. Leaflets are 0.8 to 4 cm long, 0.4 to 1.8 cm wide and "narrowly elliptic or oblong" in shape. The tops of the leaflets are dark green and the underside is "greenish gray" with sparse fine hairs. The calyx curves inward in a funnel shape. The flowers have purple petals and a white throat, and are 4.5 to 6.5 cm long and 3 to 5 cm wide at the mouth. The fruit is "subwoody", growing 5 to 6.5 cm long and 2.6 to 3.5 cm wide. References {{Taxonbar, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinnation
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or " fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, ...

Jacaranda
''Jacaranda'' is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas. The generic name is also used as the common name. The species '' Jacaranda mimosifolia'' has achieved a cosmopolitan distribution due to introductions, to the extent that it has entered popular culture. It can be found growing wild in Central America, the Caribbean, Spain, southern Africa, China, and Australia. Etymology The name is of South American (more specifically Tupi-Guarani) origin, meaning fragrant. The word ''jacaranda'' was described in ''A supplement to Mr. Chambers's Cyclopædia'', 1st ed., (1753) as "a name given by some authors to the tree the wood of which is the log-wood, used in dyeing and medicine" and as being of Tupi-Guarani origin, by way of Portuguese. Although not consistent with the Guarani source, one common pronunciation of the name in English is given by . Description The species are shrubs to large t ...
