specimen of an Erythrina belonging to this section, collected in Langkawi. The 

 flowers are precisely those of E. suberosa, a glabrous form of which is common in 

 Burma and Tenasserim ; it may, therefore, well belong to that species. But the 

 solitary branchlet is densely prickly whereas it is a feature of both the tomentose 

 Indian and the glabrous Indo-Chinese form of E. suberosa to have almost unarmed 

 branchlets. As moreover, Mr. Curtis' specimen is without leaves, the writer cannot 

 on its authority alone, formally include E. suberosa among the Malayan species. 



Subgen. 3. Hypaphorus Hassk. Calyx campanulate more or less 

 distinctly 2-lipped, but not splitting down to the base. Pod flat seed- 

 less and indehiscent below, 1-3-seeded towards upper half. 



3. Erythrina lithosperma Miq. Flor. Ind. Bat. I, 209 not of Blume. 

 A tree 40-60 feet high with spreading branches, bark white, stem 2 feet in 

 diam., armed with strong prickles. Leaves 10-12 in. long ; petioles 4-5 in. 

 long with a few prickles or unarmed, when young brownish-grey 

 puberulous soon glabrous ; leaflets 3 membranous uniformly bright 

 green densely brownish-grey puberulous when young soon quite glabrous, 

 triangular-ovate cuspidate at apex, terminal wide-cuneate at base 4-6 in. 

 long 3-4 across, lateral pair rounded at base rather smaller ; petiolules 

 •3 in. long ; stipels represented by oblong glands 15 in. long *1 in. 

 across ; stipules deciduous shortly ovate-acute flaccid densely puberulous. 

 Inflorescence in short rather dense racemes 3-4 in. long on stout spreading 

 woody peduncles 5-8 in. long, flowers 1-3 in axils of minute ovate- 

 acute bracts ; pedicels *2 in. long puberulous, minutely bracteolate at 

 base of calyx. Buds puberulous ovate. Calyx "3 in. long, softly per- 

 sistently puberulous, equally 2-lipped. Corolla 1*5 in. long, standard 

 oblong obtuse, crimson or crimson with white stripes, wings and keel 

 •5 in. long subequal. Ovary compressed faintly puberulous. Pod 

 glabrous pale-yellow, 4-8 in. long, 125 in. wide in the wing like com- 

 pressed seedless indehiscent lower half to two-thirds, *6 in wide in the 

 upper 1-3 seeded dehiscent portion ; seeds subreniform '75 in. long '4 in. 

 wide, testa almost black, hilum small elliptic pale. Bak. in Flor. Brit.

 Distrib. Indo-China, from the Shan Plateau, to the Malay Archipelago. 

 Mr. Kurz, as Mr. Baker remarks, has pointed out that the present species is 

 Erythrina sumatrana Miq. ; authentic examples of E. sumatrana in Herb. Calcutta, 

 show that this is the case. But the only difference between E. sumatrana Miq. 

 and E. lithosperma Bl. (ex Miq. in Flor. Ind. Bat.), — to which Mr. Baker has referred 

 the Indo-Chinese plant that agrees in every respect with the Sumatra and Perak one, —
