nated with simple or often bifurcated, long, linear-spathulate, 

 subcostated leaflets. Those in the lower portions of the minor 

 ramulets are mostly spherical 1.5-2 mm. in diameter with long 

 stalks and simjile setaceous crown leaflets. Very young vesicles, 

 usually found at the upper parts of the minor ramulets are 

 slightly ovate or pyriform. Two or more spherical vesicles are 

 often disposed in a series with filiform links, and coronated on 

 the terminal one (fig. 10). 



Receptacles are cylindrical, acuminated above, racemously 

 arranged at the upper part of a ramulet. In the majority of cases 

 only the terminal one developes, the rest being abortive. Hence the 

 receptacles are apparently solitary and terminal on the ramulets. 



The largest specimen I have seen measured 3 feet in total 

 length. 



In other respects it is similar to Cystophyllum sisymbrioides.

Diagnosis. Radice hemisphœrico-scutelata, caule siniplici, teretiusculo, ramis 

 iindique egredientibus ; ramis fîlifonnibus, compressis, inermibiis, decom- 

 posite pinnatim ramulosis, piunis e margine distichis ; vesiculis in petiolo 

 ipsis nunc œquale nunc breviore ellipsoideis, folio simplici vel furcate 

 coronatis; receptaculis apice ramulonim racemosiscylindraceis; caulibus 

 foliisque minute giandulosis. 



Description of the species. The present species is easily 

 recognized by the general appearance and the extreme delicacy 

 of every part of the frond. The indefinite branches at the lower 

 portions of a frond attain greater length than those at the upper, 

 so that the entire plant is densely ccespitose and fastigiate,
