More striking still is the proportion of genera to species. In the 

 whole of British India it is 1:7, and in the Bombay Presidency 

 1 : 2-6. This difference is due to the fact that of the 970 genera of 

 the Bombay Flora there are not less than 592 genera with only one 

 species. On the whole, the various genera are poorly represented 

 with regard to the number of their species. There are only 10 genera 

 with more than 20 species, and the number does not rise higher 

 than 35. The dominant genera are the following (to which are 

 appended, in brackets, the number of species) : — Andropogon (35), 

 Crolalaria (32), Panicum (30), Cyperus (28), Tndigofera (27), Habe- 

 naria (24), Hibiscus (23), Vitis (22), Ipomoea (21), Euphorbia (21), 

 Ficvs (18), Grewia (17), Tmpatiens (16), Cassia (16), Acacia (16), 

 Leucas (16). 



A comparison of the orders with regard to the number of genera 

 gives us the following list: — Legitminosce (82 genera), Graminece (74), 

 Compositce (52), Euphorbiacece (37), Acanthacece (36), Rubiacece('d'i), 

 Scrophidariacece (26), Orchidacece (26), Asclepiadacece (25), Labiates 

 (21), Convolvidacece (18), Urticacece (18), Apocynaceai(ll), Cyperacece 

 (17), Malvaceae, (16), Rutacece (16), Meliacece (16). 



Of the natural orders and genera not one is peculiar to the Bom- 

 bay Presidency, and the endemic species are comparatively very few. 

 The following l seem to be endemic, though I feel not quite sure 

 about each and every one, the floristic literature of the Western India 

 libraries being exceedingly poor : — Flacourtia latifolia, F. mantaua, 

 Abutilon ranadei, Woodr., A. comutum, Pavonia ceratocarpa, Gossy- 

 pium stocksii, Tmpatiens stocksii, I. dalzellii, I. pulcherrima, Crota- 

 laria prostrata, Indigo/era Dalzellii, Smilhia purpurea, Spatholohus 

 purpureus, Canavalia stocksii, Dolichos bracteatus, Flemingia tuberosa, 

 Ammannia floribunda, Diccelospermum ritchiei, Peucedanum grande, 

 Diplospora apiocarpa, D. sphcerocarpa, Psychotria Jlavida, P. 

 canarensis, P. octosulcata, Cyathocline lutea, Blumea belangeriana, B. 

 malcolmii, Nanothamims sericeus, Senecio dalzellii, Jasminum flexile, 

 Ellertonia rheedei, Ervatamia heyneana, Beauraontia jerdoniaua, 

 Sarcostemma stocksii, Iioya retusa, Oianthus urceolatus, Frerea indica, 

 Canscora concanensis, Paracaryuw malabaricum, P. lambertinuni, 

 Sericostoma pauciflorum, Utricularia albo-ccerulea, U. arcuata, 

 Blepharis asperrima, Strobilanthes sesszlis, var ritchiei, S. heyneanus,
