X. On THE GENERA WITH ARTICULATED PEDICELS AND DI- 
MEROUS OVARY. 
There are only three genera which come under this heading, Sciado- 
panax, Macropanaz, and Nothopanaz, the two former of which have 
already been treated upon; and they differ by the following charac- 
ters :— 
XVII. Sctaporanax. Stigmata 2, stylopodio conico imposita. 
Albumen ruminatum.—Arbor Madagascariensis ; foliis imparipinnatis. 
XI. Macropanax. Stylus 1, elongatus. bumen xquabile.— 
Frutices Indiz orientalis; foliis digitatis. 
OTHOPANAX. Styli 2-3, elongati, distincti. Albumen 
sequabile.—Arbores v. frutices Asize, Afrieze, et Australie ; foliis sim- 
plicibus v. pinnatim digitatimve compositis. 
XXVIII. Nornopanax, Miq. in Bonplandia, 1859, p. 139, et Fl. 
Ned. Ind. vol. i. parsi. p. 765. Pedicelli articulati. Flores calyculati, 
polygami. Calycis tubus obconicus ; limbus minute 5-dentatus. Pe- 
tala 5, sestivatione valvata. Stamina 5. Styli 2 (per excessum 3), 
dein divergentes, fere ad basin usque facie interiore stigmatosi. Ova- 
rium 2., rarissime 3-loculare. Drupa didymo-compressa v. rarissime 
Albumen sequabile.—Frutices sepius anisati; foliis decom- 
Wem pets digitatis v. simplicibus; petiolis basi stipulatim dila- 
iatis; umbellis decompositis v. racemoso-paniculatis, floribus parvis 
afbidis v. viridiusculis.— Panacis, Aralie, et Paratropie sp. auct. 
ANothopanaz was established in 1856 by Miquel in the * Bonplandia * 
for a set of shrubby Hederacee having articulate pedicels, polygamous 
5-androus flowers, and a two-celled ovary. The generic character there
