21 INTRODUCTION. 
Jhina to the Philippines, with a southern group, which extends from Western and ете. 
India to Malaya and Papuasia, leaving a wide belt in Northern India and Centra an 
Southern Indo-China without any representative of the section. The seetion Š Podio- 
petalum, on the other hand, more or less occupies this intermediate space, overlapping, 
it is true, the area belonging to the northern group of 7riptolemeas, but leaving the 
area occupiel by the southern group quite free. The two most western Podiopetala 
(D. Sissoo and D. confertiflora) ате rather widely spread; the remainder are mostly 
quite localised. 
In the section Š Endespermum, which is not quite so large as Triptolemea or as Dalbergaria, 
we һауе the same wide diffusion on the part of some of the species, notably on that 
of D. torta, which occurs on every shore except, apparently, those of Coromandel and 
ot Java; of D, rostrata, which extends from Southern India throughout Malaya to Papuasia; 
of D. densa, which extends from the Moluccas to Australia; and of D. tamarindifolia, 
which is found throughout Malaya, Indo-China, and the Philippines, and extends to 
South-Western China and the Central Himalaya, Another species, D. congesta, has a remark- 
ably dissociated distribution—not, however, a unique feature, since D. paniculata among 
the Dalbergariae exhibits the same peculiarity. 'l'he more localised species show the 
tendency to group themselves in a northern and a southern series of forms that we 
have already met with in #riptolemca; Northern India and, save for the presence of 
D. tamarindifolia, Central Indo-China being remarkably free from forms of this section. 
The Asiatic Miscolobia, very like the Asiatic Podiopetaia, occupy mainly the middle 
region which the Triptolemeae entirely and the End-sperma so largely avoid. With the 
exception of D. borneënsis and D. polyatelpha, the species of the section § Miscolobium, 
though rarely widely distributed, are not very narrowly circumscribed. None of the 
Miscolobia extend to Papuasia. CS 
The section 5 Dulbergaria, which may also be divided into a class of localised and 
a class of widely-diffused spevies, shows no tendeney to segregation into а northern and 
a southern group, but is fairly uniformly distributed throughout South-Eastern Asia. 
` The widespread species are not, however, quite so numerous as compared with the 
localised ones, as was the case with Endespermum or Triptolemea; the most diffused 
being D. ferruginea, which fills Papuasia without, however, touching Australia or Melanesia ; 
D. lanceolaria, which is spread throughout India; D. stipulacea, which is spread through- 
out Indo-China; and Л. volubilis, which practically occupies the ‘whole area filled 
by the two preceding species. D, paniculata has the samo dissociated distribution аз: 
D. congesta, The localised species are chiefly Indo-Chinese and Chinese, |
