the accompanying plate has been submitted, is of opinion that 
G. Ghiesbrechtiana, together with G. spicigera, C. Koch, merit 
subgeneric distinction from the true Geonomas. In 1859, he 
published these species as generically different under the name 
Calyptrogyne ; but now he informs us he is not disposed to 
attach so much importance to their points of difference, and 
so sinks Calyptrogyne as a subgenus of Geonoma, differing from 
the typical species in some minor details of floral structure, 
which need not be enumerated here. 
Descr. Stem short or wanting. Leaves pinnate, two to 
five feet long, pinne opposite or alternate, sessile, of unequal 
breadth,the narrower one to two-nerved, the broader six to ten- 
nerved, usually from six to twelve on each side of the rachis; 
the intervals between the pinne varying from half an inch 
to two inches. Petiole broadly sheathing at the base, from a 
few inches to one and a half feet long. Peduncles erect, over- 
topping the leaves, bearing a single cylindrical undivided 
spadiz nine to twelve inches in length. Spathe. elongate- 
linear, acute, shorter than the spadix, at length deciduous. 
MALE-FLOWERS numerous and rather crowded, in threes, 1m- 
mersed in depressions of the spadix ; distinctly exserted on 
expansion. Perianth double, six-leaved, three outer segments 
concave carinate, inner concave and narrower. Stamens six, 
filaments united nearly to the apex. FEmMALE-FLOWERS ex- 
serted, patent. Outer perianth three-leaved, inner cylindri- 
conical, the upper calyptriform portion separatin g transversely 
and deciduous. Abortive staminal-tube cylindrical six-toothed, 
surrounding the ovary, adnate below with the inner perianth. 
Ovary three-celled, two cells abortive ; style tripartite elon- 
gate; stigmas three, recurved, slightly protruded. (Descrip- 
tion chiefly taken from Dr. Wendland’s Memoir, cited above.)
