Іп Рілте 2 and Рілте 3, which illustrate this chapter, an attempt has been made 
to represent graphically the facts expressed in the preceding tables. In these plates the 
sub-subareas (РгАТЕ 2), provinces (PLATE ЗА), and subareas (PrarE 3B) are indicated by 
circles the areas of which are in proportion to the number of species hitherto collected 
within each. Sub-subareas within which no endemic вресіев has been found are enclosed 
in single, the others in double lines. Tho distribution of individual Species is indicated 
in the series of small maps which occupy Рілте 4. | ! 
When the distribution of Dalbergia by natural sections is examined, it is found 
that Š Zriptolemea is only represented in China by a single subendemic group of 
three species, the {J Mimosoides, and by D. rimosa of the є Réimosae. India too has few 
species of this section; one of them a coast plani ( D. spinosa), and three others—two of 
them, however, endemie,—all of them T Phyllanthoides, Indo-China is still more poorly 
endowed; east of the Irrawaday we find only the same coast species (D. spinosa); 
west of that river occur D. spinosa, one of the Chinese group (€$ Mimosoides), and boo 
other species, both of them € Rimosae, Malaya has but one representative of the Indian 
group 4 Phyllanthoides;. the species is, however, an endemic one; there are, besides, 
five endemic є Rimosar, of which group therefore Malaya is clearly the head-quarters. 
Two other species—D, discolor and D. parviflora—Malaya shares with Papuasia; another 
species (D. Beccarii) is endemic. Papuasia, besides the two species just mentioned, has 
three endemic ones—D, Albertisit, D. Cumingiana and D. Mimcselia, Malaya has ; thus
