EXPLANATION OF TAB. VIII. 
Fig. 1, flower and bracts; 2, flower, with bracts removed; 3, stamens and pistil; 4, anther; 5, 
| sepal; 6, petal; 7, pistil and remains of filaments ; 8, vertical section of ovary; 9, transverse 
section of ovary; 10, ovule; 11, ripe fruit ; 12, vertical section of the same, showing the plu- 
mule of the solitary seed; 13, vertical section of the same through the cotyledons ; 14, cross 
section of the exalbuminous seed, the testa of which has been absorbed during maturation. 
There seems little doubt that the plant at first imperfectly described by Planchon and 
Triana is the same as the Panama plant, of which there is abundant material at Kew, 
collected by Hayes. The only points of difference are the apparently 5-celled ovary 
and white flowers of the Colombian specimens. 
Altogether this is one of the most singular plants that has come under our observa- 
tion ; and therefore we have given the generic character. The fact that the testa of the 
seed is almost wholly absorbed during maturation, leaving the embryo lying naked in 
the fruit, is of itself exceedingly interesting. The plumule, as described above, is 
largely developed in the dormant seed; and, according to a note in Hb. Kew, by 
Hayes, it grows in germination to a considerable length before the radicle begins to 
elongate.
