forming continuous septa between the seeds; the sutures thickened. 

 Species 5 or 6, all American ; one introduced and now becoming sub- 

 spontaneous in S.-E. Asia. 



Enterolobium Saman Prain. A large spreading tree 40-60 feet high, 

 stem 3 feet or more thick, branches pubescent. Leaves evenly 2-pinnate, 

 rachis4-6 in. long, pubescent, basal gland none but with glands between 

 the bases of each pair of pinnae, single in the upper, paired in the lower 

 half of the rachis ; pinnae 4-6-jugate, 2-3 in. long, rachises pubescent 

 with glands between each pair of leaflets ; leaflets decreasing down- 

 wards, 6-8- jugate in the upper, 3-5-jugate in the lower pinnae, ovate- 

 oblong rigidly coriaceous, glabrous above, densely pubescent beneath, 

 apex obtuse, base obliquely truncate,, main-nerve diagonal, terminal 1*5 

 in. long, *8 in. wide; stipules small lanceolate, densly pubescent, 

 deciduous. Flowers in dense heads 1*25 in. across, on pubescent pedicels 

 25 in. long, solitary or 2-3 together in the axils of the upper leaves, 

 each with a lanceolate pubescent bract 15 in. long and a slender puberu- 

 lous pedicel *05 in. long. Qalyx infundibuliform, densely pubescent ex- 

 ternally, '15 in. long, teeth wide-triangular, short. Corolla pinkish, infun- 

 dibuliform, *3 in. long, tube puberulous outside, teeth ovate, externally 

 pubescent, half as long as tube. Filaments pink, 125 in. long, connate at 

 bnse in a tube one-third as long as that of corolla. Pod straight, 6-7 in. 

 long, -6 in. wide, '35 in. thick, valves slightly depressed between the 

 seeds, sutures thickened, epicarp thinly crustaceous, mesocarp pulpy, 

 endocarp firmly crustaceous and forming continous septa between the 

 seeds. Seeds 16-20, transversely ovate, '4 in. long, '25 in. wide, *2 in. 

 thick, testa smooth brown shining with distinct duller darker-brown 

 ovate areola, without arillus. Inga Saman Willd. Sp. PI. IV, 1024. 

 Pithecolobium Saman Benth. Hook. Lond. Journ. Bot. Ill, 216. Cal- 

 liandra Saman Griseb. Fl. W. Ind. 225. The Rain Tree. 



Planted in many of the provinces and now appearing subspon- 

 taneously, at least in the Andamans and Nicobars. A native of Guiana; 

 introduced in the West Tndies whence it has been sent to Asia. 



This species, though of much more recent introduction than Pithecolobium dulce, 

 is also of some economic importance, owing to its rapidity of growth and the 

 readiness with which it thrives, as compared with most native species, when used 

 in the re-nfforestation of abandoned clearings. The sweet pulpy pods, of which it 

 produces an abundant crop, are greedily eaten by cattle. 



When Mr. Bentham tentatively placed the species in Pithecolobium he explained 

 that the tree was unknown to him. Dr. Grisebach, who had the advantage of study- 

 ing the tree in the living state, at once recognised that it cannot possibly be a 

 Pithecolobium and placed it in Calliundra, no doubt owing to the sutures of its pods 

 being thickened as in that genus. That the pods nre septate and indehiscent mili- 

 tates however against his proposal, for the crucial test of a Calliandra is that its pods, 

 which may not be septate, shall dehisce elastically from apex to base. The Index
