Bentlmm states that this species was found by Reeves at Canton as well ns by 

 varioua collectors in Hong-Kong. Herasley, however, says that Reeves' specimens 

 are without locality. This species is very closely related to the next, though the 

 two are nevertheless specifically quite distinct. 



22. Ormosia venosa Balcer in Booh. jil. Flor. Brit. Ind. ii. 254

 Malay Peninsula ; Malacca, Maingay ! 



A very distinct species, the one to which it is most closely related being the 

 preceding, which comes from a very remote locality. 



As regards distribution the most striking features connected with 

 Ormosia are (1) the wide-spread occurrence of this genus throughout 

 South Eastern Asia, from Hupeh in China to Bangka in the Malayan 

 Archipelago, and from Travancore and Nepal to the Philippines : (2) the 

 remarkably limited range of individual species with the exception of 

 0. parvifolia (0. bancana) which extends from the Malay Peninsula to 

 Bangka and Borneo, and to a less extent of 0. sumatrana which occurs 

 on both sides of the Straits of Malacca. 0. robusta also has a wider 

 range than most of the species for it extends from the valley of Assam 

 through Silhet and Chittagong to Pegu and Tenasserim. It is in- 

 teresting, however, to note that very closely related species such as 

 0. pachycarpa and 0. venosa, and again 0. yunnanensis and 0. sumatrana, 

 may occur in widely separated localities. In the first instance one of 

 the closely allied species is a native of Hong-Kong, the other is a native 

 of Malacca; the specific names of the other pair indicate their respective 

 habitats. 



From the subjoined tabular statement it will be seen that of the 22 

 species enumerated one is S. Indian ; one Himalayan ; two, but one of 

 these with two quite distinct varieties, occur in the Kachin Hills ; five 

 occur in China ; one in Tonkin; one in the Philippines ; one in Borneo, 

 though this species also occurs in Bangka and throughout the Malay 

 Peninsula ; three in Sumatra, though one of these also occurs in Malacca ; 

 and eight in the Malay Peninsula, though one of these extends to Bangka 

 and Borneo and another extends to Sumatra. The remaining species, 

 which forms a very distinct subgenus, is widely spread from Assam to 

 Tenasserim in a region where no other species occurs— a region moreover 

 which separates the two chief centres of the genus in South Eastern 

 Asia, viz. : — the Kachin-S. China area, and the Malay Peninsula. It is 

 further worthy of remark that, so far, no species has been recorded either 

 from Java or from Ceylon.
