414 D. Prain — Some additional Leguminosffl. [No. 2, 



Wight and Amott and Bentham could hardly, however, be mistaken and, at least 

 sometimes, there must be nine. 



In the jP. B. I. it is said of this that it has the habit of D. monosperma but that it 

 is readily known by its stamens and ovary. By its ovary it is usually easily known 

 since here there are almost always more than the solitary ovule which marks D. 

 monosperma. What exactly is meant by the difference as to the stamens of the two 

 species is not very clear. The F. B. I. does not say, with Roxburgh, that there are 

 10 or, with Bentham, that there are 9 in D. rubiginosa. As regards D. monosperma 

 however, it says there are two bundles of 5 each, which is never the case in that 

 species. Except that in D. rubiginosa the sheath has apparently usually 10, and in 

 D. monosperma only 9 filaments there is no difference between the two. They differ, 

 however, decidedly as to leaves, the secondary nerves being more numerous in D. 

 rubiginosa, and as to pods those of D. rubiginosa being thin membranous and reticu- 

 lately veined on the wings as well as opposite the seeds. The plant that Mr. Kurz 

 supposed to be this (Journ. As. Soc. Beng. xlv. pt. 281) is D. confertiflora. 



76. Dalbergia G-ardneriana Benth. Journ. Linn. Soc. iv. Suppl. 43. 

 This was supposed by Gardner to be only a form of D. rubiginosa of which it has 

 exactly the pods and the flowers, though the calyx is more woolly, and the leaflets 

 which are of a different shape, are densely rusty underneath ; Mr. Bentham has 

 very justly given the species a separate place. Mr. Baker, on the other hand, reduces 

 it to D. congesta ; the following diagnosis between the two species will indicate their 

 distinctness. 



Leaves rounded or obtuse, glabrous and strongly closely reti- 

 culate above, densely woolly beneath ; calyx woolly ; pod thin 

 reticulate everywhere ... ... ... ... D. Oardneriana. 



Leaves retuse or emarginate finely sparingly puberulous on both 

 surfaces, calyx glabrous, pod thick, faintly reticulate opposite 

 seeds, elsewhere smooth ... ... ... ... D. congesta. 



10. Dalbergia Junghuhnii Benth. 



Var. typica ; leaflets 7-9, oblong, glabrous or slightly puberulous.

Var. Scortechinii Prain, Journ. As. Soc. Beng. lxvi. 2. 115; leaflets 

 11-15, elliptic, more closely puberulous, as is the inflorescence.

 Distrib. Borneo. 



Unfortunately neither Griffith's Malacca plant nor Junghuhn's Sumatra one — 

 the two on which Mr. Bentham founded the species — are at Calcutta. The typical 

 variety, as here distinguished, includes all the specimens at Calcutta issued from 

 Herb. Kew. as D. Junghuhnii ; the plant separated as var. Scortechinii has either 

 been distributed unnamed or has been marked variously " near D. Junghuhnii " 

 and " near D. sympathetica.'* It has the flowers of D. Junghuhnii exactly, and 

 thus differs from D. sympathetica in having rather shorter petals. Its leaflets 

 differ equally from those of D. Junghuhnii (as represented by Curtis' Penang plant) 

 and those of D. sympathetica ; considering how closely the species of Dalbergia 

 approach each other it may be necessary at some future time to treat Dalbergia 

 Scortechinii as specifically distinct. Its pods are, however, at present unknown, and 

 it is more convenient therefore to subordinate it in the meantime to D. Junghuhnii.
