Page 535 - The stamens follow the same laws of successive developement as leaves ; and, consequently, if their arrangement be normal, they will be either equal in number to the petals, and alternate with them, or, if more numerous, some regular multiple of the petals.
Page 555 - Mucedo ; in some of these the joints disarticulate, and appear to be capable of reproduction ; in others spornles collect in the terminal joints, and are finally dispersed by the rupture of the cellule that contained them. In a higher state of composition, Fungi are masses of cellular tissue of a determinate figure, the whole centre of which consists of sporules either lying naked among filaments, as in the Puff-balls, or contained in membranous tubes or sporidia, like the thecse of Lichens, as in...
Page 556 - This consists of a single fibre, or of two, twisted spirally in different directions, so as to cross each other, and contained within a very delicate, transparent, perishable tube. They have a strong elastic force, and have been supposed to be destined to aid in the dispersion of the sporules, — a most inadequate end for so curious and unusual an apparatus.
Page 73 - Calyx closed, furrowed at base, shorter than the claws of the petals ; petals bent obliquely, linear - or obovate ; silique 4-sided, 2-edged or subterete ; seeds not margined ; stigmas forked, with the apices converging.
Page 73 - Gaudichaud found it in the Falkland Islands, and De la Pylaie in Newfoundland, while between these two points it has only been detected in the pine-barrens of New- Jersey.* . LEAVENWORTHIA.t CALYX somewhat erect, equal at the base.- PETALS equal,, cuneiform, truncate or emarginate. FILAMENTS distinct,, toothless. SILIQUE sessile, oblong-linear, compressed, somewhat inflated and torulose ; valves indistinctly nerved. STYLE distinct, or almost wanting. STIGMA minutely...

Page 4 - Corymb. In the corymb the peduncles take their rise from different heights along the main stem; but the lower ones being longer, they form nearly a level or convex top, as yarrow.
Page 625 - ZOO 125 WOOD. The most solid part of trunks and roots of trees and shrubs. It is also applied to the part of herbaceous plants between the bark and pith.. The concentric layers of the wood and bark are the reverse of each other; the former increasing externally, the latter internally. The former having a zone of cellular tissue inside, and of woody fibre and ducts out-side; the latter having a. zone of woody fibre with a few ducts inside, and of cullular tissue outside. Wood probably consists of...
