 Chinese plant (Henry n. 3865).

A shrub 3-4 feet high, branches few virgate cylindric. Leaflets thin, glabrescent 

 above, finely hairy on both surfaces, especially beneath. Flowers numerous, racemes 

 about as long as leaves. Calyx silky, tube campanulate, teeth short triangular acute. 

 Pod lj in., slightly recurved and 4-angled, pointed and much constricted between 

 the seeds, sparingly silky. 



This has been compared by Mr. Baker and by Dr. Trimen with I. tinctoria ; 

 in the writer's opinion the original comparison by Dr. Thwaites with I. flaccida 

 (I. subulata) more truly indicates its natural affinities. It has quite the habit 

 and appearance of I. subulata and is much less like I. tinctoria in facies. The F. B. I. 

 compares I. subulata with I. trita but, so far as Calcutta specimens go, and we have 

 22 different gatherings of that species, all very uniform, the resemblance is far from 

 striking ; I. trita is always a much more rigid shrub than any of the three men- 

 tioned ; I. subulata indeed is subscandent. 



Both I. subulata and I. marginulata are described by Mr. Baker (the former by 

 Dr. Trimen also), as having leaves with 5 leaflets; Mr. Baker qualifies the 

 statement further on by saying leaflets " always 5 on the leaves of the main 

 branches." In specimens collected by Dr. Wight ( Wall. Cat. 5475 and Wight, K.D. 

 667), almost all the leaves have 5 leaflets ; also in specimens obtained by Mr. Gamble 

 in the Anamallai Hills (Gamble n. 14592). In the only specimen of Dr. Roxburgh's 

 collecting at Calcutta (from Golconda) and in Ceylon specimens (Thivaites n. 1460, 

 Beckett n. 2378), the majority of the leaves have 7 leaflets. 



Dr. Trimen describes I. constricta as having 9 leaflets. This is true of Thwaites 

 n. 3811 and Talbot n. 788 but in Talbot n. 320 as many of the leaves have 11 leaflets 

 as have 9.

28. Indigofera tinctoria Linn. 



As Mr. Kurz has pointed out (Journ. As. 80c. Beng. xlv. pt. 2. p. 269) Indigofera 

 Anil is a very common wild or semi-wild species in Burma. It has now similarly 

 found its way into the Andamans and become quite naturalised. Specimens from 

 India are very rare. Mr. Kurz proposes that I. Anil shoald be looked on as a 

 variety of I. tinctoria, a proposal for which there is much to be said. But Mr. 

 Kurz's further belief that the Indigofera argentea var. coerulea of the F. B. I. should 

 also be referred here seems quite untenable ; that plant is, without any doubt, a form,
