7. Ormosia microsperma Bak. in Flor. Brit. Ind. II, 253. A 

 tree 40 to 60 feet high with thick, densely brown-velvety branches. 

 Leaves 8-10 in. long, leaflets 11-13, oblong or obovate, acute or snbobtuse, 

 base broadly rounded, rigidly coriaceous, dark-green, glabrous rather 

 glossy above, densely persistently shortly brown-pubescent beneath as 

 are the rachis and petiolules, 2*5-4 in. long 1*5-2 in. wide, secondary 

 nerves 7-9 pairs, slightly raised beneath. Racemes in ample terminal 

 fastigiate panicles, 8 in. long, 6 in. across, with densely velvety rachis 

 and branches ; pedicels 07-12 in. long, much shorter than the calyx, 

 bracts ovate-lanceolate, densely velvety, persistent, *25 in. long, bracteoles 

 at base of pedicels similar but smaller (12 in. long), two bracteoles 

 close under calyx 1 in. long, oblong. Calyx '25 in. long, externally 

 densely velvety, 3 lower teeth as long rs calyx 2 upper rather shorter. 

 Corolla white, *45 in. long, standard 35 in. wide. Stamens quite free, 

 exserted, incurved. Ovary densely velvety, 3-4-ovuled. Pod *6 in. 

 across, irregularly orbicular if 1-seeded, oblong and 1-1*2 in. long if 

 2-seeded, lineate between the seeds, the valves thinly woody, rigid, 

 glabrescent or persistently velvety. Seed ovoid *3 in. long, *25 in. wide, 

 cinnabar-red, without arillus. 



Var. typica ; pedicels very short, pods when ripe glabrescent. 

 0. coarctata Kurz, Journ. As. Soc. Beng. XLII, 2. 71 hardly of Jackson. 



Malacca ; Griffith 1759 ! Maingay 532 ! Berry 1090 ! Perak ; near 

 Ulu Selangor, Kunstler 8767 ! 



Var. Ridleyi ; pedicels distinct, pods more persistently pubescent. 



Singapore ; Selitar, Ridley, 5574 ! 



The specimens collected by Dr. Griffith have been named by Mr. Bentham 

 " Ormosia coarctata ? Jacks." and those collected by Dr. Maingay have been defi- 

 nitely issued as Ormosia coarctata ; Mr. Knrz too, has accepted this determination. 

 Mr. Baker however finds that the identification of Griffith's and Maingay's 

 Malacca plant with O. coarctata Jackson {Trans. Linn. Soc. X, t. 25 ; a plant from 

 Guiana J cannot be sustained. 



Ormosia micros perma is nearly related to O. sumatrana (Macrotropis sumatrana 

 Miq.) and is also closely related to Chse.nolooium septemjugum Miq. and C. decem- 

 jugum Miq. (Flor. Ind. Bat. Suppl. 302). Mr. Kurz reduces the genus Chsenolobium 

 to Ormosia (Journ. As. Soc. Beng. XLII, 2. 71); in this he is certainly right. He, 

 however, further considers that both plants are but forms of the same species and 

 that moreover they are both referable to O. microsperma. So far as the material 

 that was at Kurz' disposal goes this appears to the writer to be a premature conclu- 

 sion, and it seems better for the present to keep Miquel's plants specifically apart. 



Mr. Ridley's plant from Singapore differs very considerably from the Perak and 

 Malacca one. The pods are described as hairy in the field note ; they are so in the 

 specimens themselves, but those at Calcutta are not quite ripe. If the pods prove 

 to be quite persistently velvety it will probably be necessary to treat the plant as 

 a distinct species to be named O. Ridleyi.
