676 Mr. BENTHAu's Account of two new Genera allied to Olacineæ. 
misunderstood by others, who have imagined that the broad umbilicus is di: 
rected towards the apex of the fruit *. 
In Apodytes, and (as far as I can ascertain from unripe fruit or descriptions) 
in Pogopetalum, Icacina and Gomphandra, where the placenta is combined 
with the side of the fruit, the seed is pendulous from near the top of the cell, 
and the radicle is consequently next the hilum. 
The most important of the above variations of character may be condensed 
in the following synoptical view of the order. 
OLACINES, 
Calyx parvus, liber v. basi adnatus, truncatus v. denticulatus, fructifer per- 
sistens immutatus v. auctus. Corolle petala 4, 5, v. 6 hypogyna v. sub- 
perigyna subcoriacea, æstivatione valvata, libera v. per paria connexa v. 
. basi in tubum coalita. Stamina definita, cum petalis inserta, iis coalita 
v. libera, numero petalorum dupla v. æqualia, fertilia rarius asymmetrica, 
alterna sepe sterilia difformia. Anthere introrsæ biloculares, loculis 
rima longitudinali dehiscentibus. Ovarium toro nunc parvo, nunc in- 
crassato et interdum cum calyce concreto insidens, uniloculare (nunc 
spurie et incomplete 3—4-loculare), v. rarius excentrice triloculare. Ovula 
in loculo 2, 3, v. 4 collateralia, rarius solitaria, ab apice placenta liberæ 
v: ovario v. dissepimentis spuriis connate pendula, anatropa. Stylus 
erectus simplex; stigmate nunc truncato tenui, nunc incrassato 2-, 3-, 
4-lobo. Drupa calyce immutato stipata v. ampliato cincta, velata, v. 
adnata; pericarpio tenui carnoso v. exsucco, putamine crustaceo v. os- 
* De Candolle (Prodr. i. p. 531) says, Semen pendulum, basi umbilicatum ;” Lindley (Introd. 
p. 32) has, “Seed pendulous;" and Wight and Arnott (Prodr. p. 88), „Seed usually pendulous,” 
without mention, however, of the broad apparent umbilicus, which, rather than the real inconspicuous 
umbilicus, appears to me to be alluded to by DeCandolle. Endlicher (Gen. PI, p. 1041) enters into 
more detail: Semen inversum..

whole length of the embryo,” gives a tolerably fair idea of the outside of the seed with the trace of 
the placenta. it : j
