REVISION OF THE NATURAL ORDER HEDERACEJE. 
Bv BremrHorD SEEMANN, Pu.D., F.L.S. 
(Continued from Vol. V. p. 286.) 
On THE Genus KissODENDRON. 
(Puare: LXXIX.) 
The genus Hedera, as circumscribed by me, is very natural, and 
easily distinguished from all other Hederacee by its climbing and 
rooting branches, simple leaves, inarticulate pedicels, five petals and 
stamens, semi-inferior ovary, single style, and ruminate albumen. Dr. 
F. Mueller referred to it an Australian species, which has, however, ar- 
ticulate pedicels, a completely inferior ovary and compound leaves, and 
is held by me to be the type of the genus Kissodendron. This genus 
resembles Pentapanax, Seem. (Journ. of Bot. Vol. IÉ p. 294), both 
having pinnated leaves and an arboreous habit, but they differ in the 
ollowing points :— 
Pentapanaz. Petala æstivatione imbricata. Drupa exsucca. Albu- 
men equabile. India orient. 
Kissodendron. Petala wstivatione valvata. Drupa baccata. Albu- 
men ruminatum. Noy. Holl.
