430 D. Prain — Some additional Leguminosee, [No. % 



in the F. B. I. ; even if the two are not to be treated as distinct species, they are, in 

 any case, quite deserving of varietal rank. They may be distinguished as follows : — 



1. Dolichos Lablab Linn. ; pods longer, more tapering at point, seeds with 

 Jong axis parallel to sutures. D. Lablab Linn. Sp. PI. 725. D. lignosus Boxb. Flor. 

 Ind. iii. 305 not of Linn. Lablab vulgaris Savi Diss. 19 ; DC. Prodr. ii. 401 ; W. Sf A. 

 Prodr. 250 ; Miq. Flor. Ind. Bat. i. 189. D. cultratus ForsTc. Flor. Aegypt.-Arab. 134. 



2. Dolichos lignosus Linn. ; pods shorter more abruptly truncated at end, 

 seeds with long axis at right angles to sutures. D. lignosus Linn. Sp. PI. 726. D. 

 Lablab Boxb. Flor. Ind. iii. 307 not of Linn. D. cultratus Thunb. Trans. Linn. Soc. 

 ii. 320 not of Forsh. Lablab cultratus DO. Prodr. ii. 402 ; W. 8f A. Prodr. 251 ; Miq. 

 Flor. Ind. Bat. i. 190. L. microcarpus DO. Prodr. ii. 402 ; Miq. Flor. Ind. Bat. i. 190. 



Here, as in the case of Phaseolus Mungo and P. radiatus, Eoxburgh has reversed 

 the incidence of the Linnean names, no doubt because of the fact of that the 

 epithet " lignosus " is so much more appropriate when applied to " Lablab " than 

 when given to the plant to which Linnaeus assigned it. That D. lignosus Roxb, 

 cannot be D. lignosus Linn., both Wight and Walker- Arnott in their Prodromus, 

 and Miquel in his Flora of the Dutch- Indies have already pointed out. But Wight 

 and Arnott have considered that Linnaeus and Roxburgh had the same plant in view 

 when describing D. Lablab. This is hardly possible ; Roxburgh identifies with his 

 " Lablab " the plant figured by Rumphius in Herb. Amboin. v. t. 136, an identification 

 that is obviously just ; Linnaeus gives this very figure as one of the types of his D. 

 lignosus. 



6. Dolichos falcatds Klein. 



Add to synonyms of F. B. I. : — Phaseolus tenuicaulis Kurz in Journ. 

 As. Soc. Beng. xlv. pt. 2. 249, perhaps not of Bale, in Flor. Brit. Ind. 

 ii. 201. Dolichos tenuicaulis Grah. in Wall. Cat. 5598 D. (at Calcutta). 

 Mr. Baker's Phaseolus tenuicaulis is based on Wall. Cat. 5598 D. Excellent, 

 specimens, exactly agreeing with the Calcutta example of this sheet, were obtained 

 by Dr. J. Anderson in Upper Burma, and Mr. Kurz, with these before him, has ■ 

 inadvertently published this name without noting that the plant is simply Dolichos 1 

 falcatus. As Mr. Baker finds that the examples of Wall. Cat. 5598 D. which he has 

 examined represent a Phaseolus, it must follow that Dr. Wallich mixed two plants 

 under this letter. But from Mr. Baker's description the Phaseolus in question 

 very closely resembles this Dolichos, and no one except Dr. Wallich has collected that 

 Phaseolus in Burma or elsewhere. 



7. Dolichos subcarnosds W. #• A. 



Exactly agreeing with this in fruit but with shorter and branching 

 peduncles, is a plant common in Assam, Chittagong and Burma which 

 has flowers like those of Vigna Catjang except in having the style penicil- 

 late round the stigma instead of bearded down the neck. The leaves 

 however, are just as described by Mr. Baker and are not like those 

 of Vigna Catjang. 



The following numbered sheets may be quoted, and will indicate 

 the difficulty that has been experienced in localising the species.
