each side; male flowers ovate, obtuse, straight. Female spadic with very elongate 
partial inflorescences which vary from 30-50 em. in length and bear up to 12 spikelets

78. ©. Perrottetii Bece.—Slender, scandent. Leaves about 60 cm, long, the 
petiole apparently subcylindric. Leaflets rather many and approximate, more or less 
inequidistant or interruptedly equidistant, linear-lanceolate; the largest 18-20 cm. long, 
12-14 mm. broad. Female spikelets arched and deflexed, 6-7 cm. long, their spathels 
broadly  infundibuliform,  subspathaceous and surrounding the involucra and the 
flowers; areola of the neuter flower concave and deep, forming a cavity almost as 
large as the cavity of the female flower so that the two cavities are almost of equal 
size.

79. C. ahimensis Bece.— Female spadiz with rather large partial inflorescences ; 
these elongate-pyramidate, in one specimen 50 cm. long with 15 gradually shortening
