26 NEW GENERA OF S. AFRICAN PLANTS. 
formi, fauce barbatá, limbo 4-5-lobo, erecto-patenti, lobis 
sstivatione valvatis. Stamina imo corolle tubo inserta, 
inclusa; filamenta filiformia; anthere breves, cordate, ca- 
pilis longissimis intertextis connexe. Pollen trigonum. 
Ovarium disco crenato insidens, ovatum, uniloculare ; ovula 
in placenta carnosá centrali plurima, peltata. Stylus brevis- 
simus, conicus ; stigma oblongum, capitatum. Bacca corti- 
cata, globosa, unilocularis, polysperma. Semina in pulpam 
nidulantia, umbilico ventrali. Testa coriacea; embryo in 
basi albuminis cornei bilamellati brevis ; radiculá ellipsoidea, 
vagá; cotyledonibus foliaceis, ovatis, 5-nervibus.—Arbor v. 
frutex; ramis divaricatis, strictis, ramulis seepe in spinam 
excurrentibus ; foliis oppositis, 3-5-nerviis, glabris; cymis 
vix ramosis, ramulis terminantibus, densis; floribus viridi- 
bus, parvis; baccis magnis; pulpa deliciosa repletis. 
Strychnos spinosa, Lam.—E. Mey. in Herb. Drége (Krauss 
No. 99) is the type of this genus, which differs from Strych- 
nos, as defined by Endlicher, in the calyx, stamens, ovary, 
and style; and seems to be nearly intermediate between that 
genus and Ignatie. I wish it to bear the name of 
Mr. J. Brehm, of Uitenhage, a gentleman to whom I am 
indebted for many interesting botanical communications, and 
who has given me excellent specimens of this plant, from 
which my analysis has been made.
