1897.] D. Prain — Some additional Legummones, 463 



Very similar to D. thyrsijlora but easily distinguished by the florets with pedi- 

 cels *2-'3 in. long, instead of subsessile, and by the broader pods, l"5-4'5 in. long, 

 1'5 across, with 1-2 seeds. 



The Andamans specimens have rather thicker leaves than the Assam ones, and 

 in this resemble D. thyrsijlora, but the more numerous nerves to the leaves and the 

 pedicelled florets and buds readily distinguish the plant. The Griflithian specimens 

 have been issued as D. thyrsijlora, those of Mr. Clarke as D. marginata, those of Dr. 

 Wallich as Pterocarpus jloribundus. It has been impossible to employ the specific 

 name " floribunda," however, as there are already both an Aganope floribunda and a 

 Brachypterum floribundum in the genus Derris. 



Doubtful species. 



Derris acuminata Benth. 



This includes Wall. Cat. 5886 and Wall. Cat. 5901 ; the former at Calcutta ia 

 represented by two specimens and their flowers have a callose standard ; they are 

 in fact simply D. cuneifolia Bth. Wall. Cat. 5901 is unrepresented at Calcutta, but 

 the plant collected by Sir J. D. Hooker in Sikkim is here. It is the same as D. 

 microptera Bth. or, to be more precise, it is the flowering part of the plant whose 

 fruits are described by Mr. Bentham as those of D. microptera. What the plant 

 with 2-callose standard described as D. microptera may be the writer cannot say, 

 there being no authentic specimen here. But of the two very similar species that 

 have been reported from Sikkim, that with long cuspidate leaves and with most of its 

 nodes unproduced never has callosities on the vexillum, the one with its nodes 

 all produced and with leaflets that are either obtuse or if acute are not cuspidate 

 always has callosities. In any case the pod of the plant termed Derris microptera is 

 dehiscent as in Millettia. 



Derris secunda Bale. 



This is based on Wall. Cat. 5890 which unfortunately is not at 

 Calcutta. But a plant that exactly agrees with Mr. Baker's very clear 

 description has been collected in the following localities : — 



Daphla Hills ; Toruputu, 7400 feet, Lister ! Khasia Hills ; 5-6000 

 feet, G. Mann, 199 ! Badgeley ! Burma ; Nattoung Mts., Kurz. 



To Mr. Baker's description it may be added that the leaflets are as often 9 as 7 

 and that in one specimen there are 11. The pods, collected by Capt. Badgeley, are 

 thin strap-shaped 3-4 in. long, *8 in. wide, distinctly winged down the upper, very 

 narrowly down the lower suture ; seeds 2-3. This, as has already been remarked, 

 is the plant described by Mr. Kurz as Millettia monticola which thus proves to be a 

 Derris and must in all probablity take the name Derris secunda. 



Derris polystachya Benth. 



Add to description of F. B. I. : — Pod thin flat ligulate-oblong, 

 glabrous, flexible, finely veined, 3-4 in. long, 125-15 in. wide, the upper 

 wing" *25 in. wide, the lower narrower. 



Add to localities: — Bootan; King's Collectors! Sikkim; J.Ander- 

 son ! King ! Gamble ! 



The pod is very like that of D. marginata to which it is closely allied, but is not 

 so pale in colour ; this now ceases to be a doubtful species.
