OBETIA MORIFOLIA, n. sp. 
O. ramulis crassis, foliis cordato-orbicularibus late crenatis facie scabris 
dorso albido-velutinis integris vel sursum leviter trilobatis, paniculis laxis 
rhachibus setis pellucidis deflexis parcis horridis, perianthii foeminei seg- 
mentis orbicularibus ineequalibus. 
A tree, with ultimate branchlets woody, 4 in. in diam., with 
glabrous brown bark, the leaves erowded at the tip of the branch- 
lets, with large persistent brown ovate membranous stipules and 
the axillary panieles spreading at right angles from the brauch 
below the leaves.  Petioles 12-3 in. long, armed with deflexed

diam.— Forests of the province of Imerina, gathered long ago by 
Bojer, and now refound by Baron1820!  Bojer's specimen in the 
Kew collection was seen by Dr. Weddell and marked by him
