182 D. Prain — A list of the Asiatic species of Ormosia. [No. 2, 



Stamens and ovary as in O. inopinata. Pod hard flattened, with woody valves, 5 cm. 

 long, 3 cm. wide, 1*25 cm. thick, somewhat swollen opposite the 1-2 seeds, ovate-acute 

 with distinct stipe 6 mm. long and a prominent tip at apex of vertical axis remote 

 from stipe, ventral suture with blunt parallel ridges 6 mm. apart not projecting 

 beyond level of line of dehiscence ; seeds cinnabar-red with a small white hilum and 

 uo arillns, 1*25 cm. long, 1 cm. across, 8 mm. thick. 



The foliage of the two trees here treated as varieties of one species is hardly 

 distinguishable and the structure of their flowers is identical. The Native Collector 

 who has communicated the specimens of both states, however, that besides the 

 differences in colour of petals and in shape of pods and seeds, the two trees as they 

 grow look very different. If this should turn out to be the case it may be necessary 

 to treat the variety here described as a distinct species, to be known as Ormosia 

 dubia.

 (1891). 



Tonkin ; near Ta-phap, in forests, Balansa 2178. 

 This species is not yet represented in Herb. Calcutta. 



12. Ormosia laxa Prain; leaflets 15, less often 17, lanceolate- 

 acuminate, beneath and leaf-rachis and branchlets velvety, veins beneath 

 inconspicuous, medium, distinctly stalked ; pedicels long. 



Kachin Hills; Shan Busti near Sadon, 5000ft., Pram's Collector! 



A tree, with tawny-velvety branches. Leaflets lanceolate, chartaceous, 6 cm. 

 long, 2*5 cm. wide, at first finely deciduously puberulous above, densely softly tawny- 

 velvety beneath, veins 5-6 pairs slender not prominent beneath, apex acuminate, 

 tapering from the middle, base cuneate in the lower fourth ; petiolules 5 mm. and 

 main-rachis 20-25 cm. long, densely tawny- velvety. Floioers in axillary racemes or 

 few-branched pauicles 8-12 cm. long, densely tawny-velvety as are the pedicels 

 T25-T 65 cm. long, bracts and bracteoles minute, deciduous, velvety. Calyx cam- 

 panulate densely tawny-velvety outside, finely pubescent within, 1 cm. long, teeth 

 wide-triangular almost as long as tube. Corolla twice as long as calyx. Stamens 

 usually 5 fertile exserted in the open flower, sometimes 6 or 7, rarely 8 fertile— if 5, 

 6 or 7 fertile then with 3, 2, or 1 staminodes, always 2 stamens quite obsolete; 

 anthers oblong, versatile. Ovary stipitate, silky with long tawny hairs especially 

 on the sutures ; style glabrous filiform, tip circinnate, stigma oblique ; ovules 7. Pod 

 6-7 cm. long, 2*5 cm. wide, the valves black, smooth externally, slightly swollen 

 opposite the ripe seeds, very faintly ribbed alongside both sutures; seeds 2-4, bright 

 scarlet, 1 cm. long, 8 mm. wide, 6 mm. thick, separated by partitions of the pale 

 woody endocarp in which they are embedded, with no arillus. 



This very distinct species cannot be confounded with any of the hitherto 

 described Ormosias.

This species is distinguished from all the others by its climbing habit ; as its 

 fruit is not yet known its precise systematic position cannot be positively stated. 

 It seems, however, as if it might prove to be a species of § Layia. It may be
