2. C. Tallulensis, Sulliv. & Lesq. Tufts yellowish white, 

 glossy outside, brown within ; stems simple or dichotomous,

Compared with the last, it clearly differs in tlie pale yellovvisli green 

 color, tlie exactly linear leaves sub-decurrent and not excavated at tlie 

 angles, witli larger inflated basilar cells, and the costa not entirely filling 

 the leaves at tlie apex, but bordered by a band of the lamina. 



3. 0. introflexus, Bridel. Plants yellowish green above, 

 brown below ; stems short, erect : leaves apjiressed, erect-open, 

 narrowly lanceolate, canaliculate above, constricted into a long

 when dry ; costa broad, three-fifths of the width of the leaves

 late, not decurrent at base ; costa broad, flat ; areolation linear- 

 oblong, the cells only slightly larger toward the base, not
