admit this species in which the inner whorl of petals is Absent. In 
other respects the species agrees perfectly with the original diagnosis. 
Teysmann and Binnindyk's mono-specific genus Hhnpalocarpus (Miq. 
Ann. Mns. Lugd. Bat. II, 22, t, 2 fig. B.) is an unmistakable Anaxagorea 
in which the inner petals are narrow and incurved. It is probably near 
A. luzonensis. A. Gray, and A. javanica, Bl. (Sec Bcnth. and Hook fil. 
Gen. Plant. I, 957). 
13. DiaEPALUM, Hook. fil. 
Trees or shrubs. Sepals 2, large, concave, valvate. Petals 4, 
narrowly linear-spathnlate, incurved, inserted remotely from each 
other on the margin of the very broad, sub-concave torus. Stamens 
numerous; the apical process of the connective broadly orbicular, sub- 
convex. Pistils 10 to 15 or numerous, ovoid ; style short, terete; Btigma 
small, terminal ; ovule solitary. Leaves minutely pellucid-punctate. 
Flowers in long terminal peduncles, solitary or in pairs. Distrib. Three 
species, all Malayan. 
L Disepalum r.oxiiiPES, King, n. sp. A glabrous tree 30 to 40 feet 
high ; young branches slender, pale brown. Leaves minutely pellucid- 
punctate, membranous, oblong, sometimes slightly oblaneeolate, rarely 
oblong-elliptic, abruptly and shortly acuminate, the base cuneate ; 
main nerves 7 to 10 pairs, spreading, (sab- horizontal) very faint; length 
4 to 7 in., breadth 15 to 2 *25 in., petiole *25 in. Flowers on long 
pedicels, dark red, solitary or in pairs terminal, 5 in. in diam. ; pedicels 
slender, ebracteolate, 1*25 to 2 in, long. Sepals reftexed, concave, 
broadly ovate, blunt. Petals remote from each other, linear-spathnlate, 
sub-incurved, "2 in. long. Stamens numerous; apical process of the 
connective orbicular, sub-convex. Ovaries numerous, stalked, slightly 
obovoid, glabroscent or sparsely pubescent, 1-ovuled ; style short, 
straight ; stigma small, terminal. Immature carpets ovoid, sub-glabrous, 
slightly corrugated ; pericarp fleshy, fragrant. Seed solitary, ovoid. 
Johore; on Gnnong Pauti at 1,500 feet ; King's Collector, No. 231. 
Distrib. Borneo, Beccari (P. B. 1645). 
The genus Disepalum was founded by Sir Joseph Hooker on a 
Bornean shrub collected by Lobb, and the only species known to its 
founder was that described and figured under the name of D. anomalntn 
in the Linna?an Transactions (Vol. XX11I, 156, t. 20 A.) The charac- 
ters which separate the genus from any other in the family are the dimer- 
ous symmetry of the sepals nnd petals, aud the small size of the latter, 
which originate at some distance from each other from the edge of the 
broad sub-concave torus. The species here described differs from D. 
anomttlum in its arboreous habit, larger leaves, and much more numerous
