crebris, parallelis, transversis ; stipulee subulato-lineares ; flores 
axillares, parvi, umbellati. 
On a former occasion, when discussing the question of the 
relative affinities of the Icacinacee with the Celastracee, Hippo- 
eratacee, Aquifoliacee, &c.*, and determining the position of the 
former in the system}, I exhibited in a tabular form the lead- 
ing differential features of the several families that enter into 
the Celastral alliance. I now repeat the same under a more 
synoptical form, including the Goupiacee. 
1, Mstivation of petals imbricate. 
A. Stamens outside disk.

pended, with a dorsal raphe; seed albumi-

B. Stamens inserted inside or upon disk ..... ..... Hippocratacee. 
c. Stamens hypogynous; disk almost obsolete.

ledons large in regard to radicle ........ Aquifoliacee. 
8. Ovules suspended, with a! ventral(?) raphe ; 
cotyledons small....... slaw o,simahea eterno Cyrillacee. 
2. Mstivation of petals valvate 
A. Stamens inserted inside disk; ovules erect....... Goupiacee. 
B. Stamens inserted outside disk; ovules suspended Icacinacee. 
I may here observe that an essential point in the development 
of the ovules and seeds in the several groups above enumerated 
is the relative position of the raphe. It has been shown that an 
erect ovule with a dorsal raphe is a mere resupination of a sus-
