DISTRIBUTION OE THE GENERA. 



Class I. HAPLANTHEREiE : stamens each with two anther-ceUs, parallel, adnata, 

 or often dorsally attached to a soft connective. 



A. Ovule and seed anatropous. 



Tribe 1. Ophioxyle^ : 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 hUum is on the middle of one of the 



faces, equidistant from the radicular and cotyledonary extremities. 



Tribe 2. CarissejE : fruit drupaceous, indehiscent, 2-locular, or 1-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. WiLLUGHBBiEiE : fruit drupaceous, indehiscent, 1-3-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. Thevetie.e : 1 or 2 indehiscent drupes, 1- or 2-celled, cells or pseudo-cells mono- 

 spermous : seeds without pulp, oval, fleshy, peltately affixed, exalbuminous ; embryo with a 

 short radicle. 



Tribe 5. Hunterie^ : 1 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. 



Hunteria, Lepimia, Noterium, Pleiocarpa.
