All of these foliage forms are planate pinnate fronds, frequently with open venation. |
|
However, unlike planate, caroid, fastigiate, and linteloid plates, this inversion cannot be applied to camerate plates as indicated in de Verteuil and Norris. |
|
The part and counterpart of a specimen display an axis with lateral branches bearing planate pinnules. |
|
Its vegetative organs support the hypothesis that Late Devonian spermatophytes had evolved planate pinnae and pinnules. |
|
It is represented by stems, helically arranged and bifurcate fronds with two orders of pinnae and planate pinnules. |
|
These surfaces indicate that eastern Africa underwent long episodes of tectonic quiescence during which erosion processes were able to planate the surface at altitudes not too far from sea level. |
|
Besides it has remained some advantages of the thiophene linked acceptors, such as strong and board absorption in visible light region and planate backbone. |
|
The new plant described herein consists of long tapering bipinnate fronds with imbricate basal pinnae, planate apical pinnae, and unlobed, elliptical to obovate pinnules with open dichotomous venation. |
