RANDIA Linnaeus 
RANDIA RACEMOSA (Cav.) F.-Vill. Novis. App. (1880) 108; Maxim, in 
Bull. Acad. Petersb. 29 (1884) 167. 
Stylocoryna racemosa Cav. Ic. 4 (1797) 45, t. 368. 
G. E. S. 6, Mrs. Clemens s. n., locally known as sumac or sumag. 
The species is common and widely distributed in the Philippines, extend- 
ing nortward to the Liu Kiu Islands. Its other range is obscured by 
complicated synonymy, but I suspect that it is of wide distribution in the 
Malayan and Polynesian regions. I can see no reason for not referring 
here Ridley 37, from Christmas Island, south of Java, Koorders 30059 from 
Java, both distributed as Randia densiflora, and Volkens AO, from Tinian 
Island, Mariannes, distributed as “Randia nov. spec.” Randia densiflora 
(Roxb.) Benth. is certainly very closely allied, and perhaps R. racemosa 
must be reduced to that species. Equally closely allied is Randia graffei 
Reinike, of Polynesia, at least as represented by Volkens 502 and 536 from 
Yap, and Vaupel 1AA from Samoa. Stylocoryne coffaeoides A. Gray, a 
widely distributed Polynesian species, should also be critically compared. 
By some botanists the specific name racemosa would be considered to 
be invalidated by Randia racemosa Roxb., but in the uncertain state of 
the synonymy of our species, I prefer to make no change.

Frutex vel arbor parva, glabra; ramis teretibus, ramulis 
distincte quadrangulatis ; foliis oblongis vel ovato-oblongis, niti-

utrinque 7 vel 8; inflorescentiis terminalibus, corymbosis, multi-

A shrub or small tree, quite glabrous except the corolla-tube 
which is villous inside. Branches terete, brownish or brownish- 
gray, the branchlets about as thick as the ultimate branches, 
distinctly 4-angled, the internodes about 1 cm long. Leaves 
chartaceous, oblong to ovate-oblong, 8 to 12 cm long, 3 to 4.5 cm 
wide, about equally narrowed to the acute or obtuse apex and to 
the acute base, when dry dark-olivaceous, or the upper surface 
nearly black, smooth and shining, the lower surface very slightly 
paler than the upper; lateral nerves 7 or 8 on each side of the 
midrib, rather prominent on the lower surface, curved, anasto- 
mosing, the reticulations slender, very lax; petioles 1 to 2 cm 
long; stipules very early deciduous. Inflorescence terminal, gla- 
brous, corymbose, many-flowered, about 5 cm long, 8 cm wide, the 
lower branches subtended by lanceolate, leaf-like bracts (reduced
