monosperma, which the Andamanese know as puleu-da and which never grows near 

 salt-creeks but always in the interior jungle. The lianes of M. gigantea form indeed 

 one of the most striking- features of the muddy margins of our Indian Mangrove- 

 swamps. The writer when in the Great Coco was at pains to obtain one entire 

 plant, the following were its measnrements : — Diameter of main stem, close to the 

 mud, '5 in. ; at 4-6 feet from the mud there issued, from latent buds, 4 of the 

 characteristic umbelliform pendent racemes of the species, with slender peduncles 

 8-15 in. long. The first branch was at a distance of 50 feet from the root, the first 

 leaf was at a distance of 205 feet from the mud, about 200 feet from the only flowers 

 on this particular plant ; the leafy branches, only '15 in. in diam., extended 25—30 

 feet further. This feature of flowering from old wood has been met with in Mucuna 

 monosperma as well. 



During another journey the writer collected, on Little Andamans, specimens of 

 M. gigantea with pods ridged, though not plaited, across the face, thus unfortunately 

 invalidating the distinction between the " subgenera " Amphiptera and Carpopogon 

 of the F. B. I.

The Burmese plant always has the lowest calyx-tooth longer than in the Nepal 

 and Sikkim plant. In specimens collected by the writer in the Khasia hills, however, 

 the calyx is exactly as in those collected by Dr. J. Anderson at Poneshee and by Sir 

 Henry Collett in the Shan hills. The pod is so exactly alike in the Burmese and in 

 the Himalayan plants that the writer, instead of being able to adopt the suggestion 

 of Sir Henry Collett and Mr. Hemsley that the Burmese one may be a new species, 

 is not inclined to treat it as even varietally distinct. 



The perennial stems and the large circumferential hilum of the seed, mark 

 the species as undoubtedly a Zoophthalmum not a Stizolobium.

This is not confined to the foot of the Himalayas ; though found in that area it 

 is less common there than in the forests of Central India and Chota Nagpur. The 

 racemes of this are not always short, nor are the racemes of M. pruriens always 

 elongated ; the species are only distinguishable by their pods. These last are, 

 however, as Mr. Baker points out, very different.
