32 BOTANICAL BULLET IX 



erii part of Europe. It resembles a pale form of Jumi. inila'a so elosel}' in size, and 

 in the shape and texture of the leaf, that it is not easy to distinguish between the 

 two plants when they are sterile. However, besides the different character and 

 position of the colesula, etc., the latter has the leaves more closely placed (par- 

 ticularlj^ the upperones), and usually inclined to become fuscous; the stems are 

 mostly simple, sometimes forked but never with ventral branches, and the ampW- 

 gastria (extremely rare) are obtusely lobed.

Stems less tnan an inch long, not divided but proliferous from the underside 

 without ventral ttagelht. Leaves succubous. Much like C. bidentula Nees, but 

 smaller, with the teeth at the apex of the leaves more acute, the sinus more exactly 

 lunulate, amphigastria bifurcate, etc.

Island of East Maui i Sandwich), Dr. Baldwin. 1875 (Eaton). 



A very distinct species, well characterized by its slender (Omphalanthus-like), 

 habit, and by its almost entire, ovate-orbicular amphigastria. Stems 1 — 2 inches 

 long, by about }4-yi of a line wide. Color pale green.

With Sendtnera jitniperina, Sandwich Islands, Baldwin; very rare. 



About the size of Sendlncra gracilis, Xees. and somewhat resembling it, but the 

 stems are shorter and more rigid, the leaves are broader and entire and the areola- 

 tion is different, etc. Here and there a small fascicle of rootlets are found proceed- 

 ing from the base of an amphigastrium. These are hyaline, nearl}' as long as the 

 amphigastria, and have the free end pedately about 5 or i>arted. (An Mastigophora

Near Augusta, Georgia, Sullivant (1845). Aments (male spikes^ short and 

 broad, found only on the branches, which are of various lengths, terminal ^or 

 rarely interrupted . Perianth elongated, compressed-cylindrical from a pyriform 

 or obconic base, the mouth 2-lipped, the lips emarginate or crenate; its texture is 

 similar to that of the leaves. Stems ^-1 inch long, prostrate, sparinglj^ subpin- 

 nately branched, loosely ca^spitose. Leaves nearly or quite as decurrent as in B. 

 pallens ^Swartz', lobule adnate to the stem along its inner margin. R.pallens is a 

 larger species, with stems dichotomously f never pinnately) branched; aments 

 much longer, not terminal, perianths less elongated (always ?\ lower lobe of the 

 leaf smaller and less acute, areolation not so distinct, etc.
