DISTRIBUTION OF THE GENERA. 
Crass I. HAPLANTHEREA : stamens each with two anther-cells, parallel, adnate, 
or often dorsally attached to a soft connective. 
A. Ovule and seed anatropous. 
Tribe 1. OPHIOXYLEÆ : fruit drupiform and indehiscent, either single or double; cells mono- 
spermous : seed without pulp, erect, with a basal hilum and inferior radicle, or suspended 
with a superior radicle. All albuminous. 
Ophioxylon, Rauwolfia, Vallesia, Bicorona. 
B. Ovule and seed heterotropous, when the hilum is on the middle of one of the 
faces, equidistant from the radicular and cotyledonary extremities. 
Tribe 2. Carissem: fruit drupaceous, indehiscent, 2-locular, or l-celled by abortion: seeds 
imbedded in pulp, peltate, subcompressed; embryo straight, in albumen, with a basal 
radicle. Acokanthera, Ceratites, and Pomphidea are placed here on account of their 
stamens, though their fruit is unknown.

Tribe 3. W1iLLUGHBEIEZX : fruit drupaceous, indehiscent, 1-2-celled : seeds compressed, imbedded 
in pulp; embryo straight, without albumen, with a very short radicle: thus differing from the 
preceding in the absence of albumen. 
Willughbeia. 
Tribe 4. Turvetiex : 1 or 2 indehiscent drupes, l- or 2-celled, cells or pseudo-cells mono- 
spermous: seeds without pulp, oval, fleshy, peltately affixed, exalbuminous ; embryo with a 
short radicle.

Tribe 5. Huwrerizx: l to 5 oval dry indehiscent drupes, monospermous : seed compressed, 
without pulp, laterally attached by a central hilum; embryo in copious albumen, with a 
superior radicle.

Noterium, Pleiocarpa.
