470 D. Pram — Some additional Leguniinosa?. [No. 2, 



" bristles stand erect from the pod and are glabrous ; the apiculus at the end of the 

 " pod in the Burmese plant is longer and at the base more bristly than in C. minax. 

 " The leaves not being in the same state in the two specimens cannot be quite de- 

 " finitely compared. The bracts of the inflorescence of C. minax have a narrow 

 "white margin and the head is more broadly conical than in the Burmese plant. " 



Both Mr. Baker and Mr. Britten think therefore that the Burmese plant cannot 

 be considered typical C. minax. One other difference may be mentioned ; the 

 flowers are noted as " white " in the Shan Hill specimens, Mr. Hance mentions 

 " purple " in connection with the Chinese one. As a temporary measure it is treated 

 here as only a variety of C. minax but it may ultimately be necessary to recognise 

 in it a distinct species, to be known as Ceesalpinia burmanica.*

3. Cjisalpinia Nuga Ait. 



The species that is most nearly allied to G. Nuga is Mezoneuron sinense Hemsl. 

 which, with the habit of G. Nuga, has also pods that are very similar in shape and in 

 consistence and differ only in being narrowly winged down the upper suture. 

 Perhaps the most convenient and at the same time most natural arrangement would 

 be to remove M. sinense from Mezoneuron and at the same time to take C. Nuga out 

 of Csesalpinia treating them as congeneric and as types of a genus Nugaria equally 

 related to, but equally distinct from, both Csesalpinia and Mezoneuron. Still the 

 mere fact of having pods slightly winged along the upper suture hardly prevents 

 the Chinese species from being treated as a Csesalpinia, since G. sepiaria presents 

 in Subgen. Eucsssalpinia, though not so markedly, the same peculiarity. The 

 Chinese plant certainly must be removed from Mezoneuron. 



4ib. C^salpinia parviflora Prain, Joum. As. Soc. Beng. lxvi. 2. 

 230; puberulous, pinnae 18-24, leaflets 30-36, usually small, oblique, 

 the lower corner auriculately produced, stamens little exserted, pod 

 oblique 3-4-seeded ; leaves stipulate ; flowers very small and numerous. 



Var. typica ; leaflets not exceeding *5 in., stipules lanceolate, de- 

 ciduous. 



Perak ; at low elevations, Kunstler ! Wray ! 



Var. ? stipularis Prain, loc. cit. ; leaflets exceeding *75 in., stipules 

 ovate-obloug, persisting. 



Perak ; in the plains, Wray / 



A climber, or sometimes arborescent ; prickles small and few. Leaflets rachis 

 8-10 in. long ; leaflets close sessile subcoriaceous, attached in middle of base but 

 with lower corner auriculately produced. Panicles very long, and usually again 

 branching, the young branches rusty-pubescent ; bracts small linear or lanceolate, 

 deciduous ; pedicels *25 in. Calyx '25 in., puberulous. Filaments densely woolly in 

 the lower half. Ovary sparsely puberulous. Pod 1 in. long, '5 in. wide, like that 

 of a miniature C. Sappan. 



This Csesalpinia in foliage resembles C. tortuosa and C. microphylla but its pod 

 is that of a small C. Sappan ; by its very small greenish-yellow flowers it is quite 

 distinct from all the other Indian ones. The variety may prove a distinct species. 



* Since this was written the Calcutta Garden has succeeded in obtaining seeds of 

 this very interesting species from the Shan Hills, and these have been distributed 

 to the leading Botanic Gardens in both Hemispheres.
