This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1892 Excerpt: ...reduced. In 8 these elements are of large size and are slightly thickened, while in 2 all the roots that I have yet examined approach nearer to 3 than to 1. In 1 the pitted vasa are 18 i across, in 3 they are 35 fi, and in 2 they are 28 jn. Longitudinal root sections of 1 show cortex cells from the third layer inwards, which are greatly elongated and have thick, white, colloid walls. In 3 these are loose, thinwalled, slightly irregular in shape, and are, on the average, rather broader than long. In 2 the cells are considerably longer than broad, and show a moderate degree of colloid thickening. Stem.--Only a few details need be referred to here. On transverse and longitudinal section of the cortex of 1, the cells are greatly elongated; their walls are thickened so that slit-like deficiencies with pore apertures are left, and between the cells are small intercellular spaces. In 3 the cells are slightly longer than broad, many have no thickening deposits, but a few show a very pretty secondary spiral thickening. Many of the cells surround large intercellular spaces. In 2 the shape and size of cells, as also the size of the intercellular spaces, are not only intermediate, but spiral cells like those of 3, though with less thickening deposit, are distributed among the unthickened ones.

Leaf.--Each leaf is divisible into a terminal laminar portion and basal persistent petiole. Between the pseudo-bulb and petiole, also between...
