Very closely related to M. cinerea; its smaller firmer leaflets and its much 

 larger buds and flowers give it however, in all stages, a facies of its own. 



The authors of the species had, they write, considerable hesitation about giving 

 specific rank to this plant which they think may perhaps after all be only a variety 

 of M. cinerea. Dr. King has very kindly examined the specimens with the writer 

 and likewise agrees in thinking that Sir H. Collettand Mr. Hemsley were justified in 

 according it specific rank. It is of tener a climber than a tree ; fruits are still 

 unfortunately wanting. 



15. MlLLETTTA GLAUCESCENS KuYZ. 



Add to localities of F. B. I. : — Sikkim ; Terai at Panchenai and 

 Chunbati, Gamble 689 ! 2240 ! Malay Peninsula ; Perak, Wray n. 168 ! 

 Ridley ! Scortechini ! 



Both in Sikkim and in Perak this is an erect tree. Its affinities are altogether 

 with M. pubinervis, M. Hemsley ana, M. Wrightiana, M. dehiscens and M. decipiens. 

 Like these species it has a 2-callose standard and ought perhaps to be removed from 

 the section in which it is placed in the F. B. I. 



The following key may assist in explaining the relationships of the species 

 of the group to which M. glaucescens belongs, all the members of which have 

 exstipellate leaves, and all of which except M. glaucescens itself have densely 

 silky ovaries. 



Standard pubescent on the back, (flowers pink) : — 

 Leaflets 5-7, thinly adpressed-silky beneath, 



ovules 2... ... ... ... 1. Millettia (sp. borneensis.) 



Leaflets 7-9 with only a few sparse hairs on 

 midrib beneath : — 



Ovules 4 ..♦ ... ... 2. Millettia decipiens. 



Ovules 5 or more ... ... ... 3. Millettia dehiscens. 



Standard glabrous on the back, (ovules 6) : — 

 Standard longer than broad, flowers yellowish- 

 white or white : — 

 Petals yellowish-white with purple veins, calyx 



black-purple, stipules and bracts small ... 4. Millettia pubinervis. 

 Petals white flushed with pink, calyx green 

 tinged with claret, stipules and bracts 

 large ... ... ... ... 5. Millettia Hemsley ana. 



Standard as broad as long, flowers blue : — 



Pod thin without lenticels, sutures not winged 6. Millettia Wrightiana. 

 Pod thick woody lenticular, sutures winged ... 7. Millettia glaucescens. 

 The Bornean species mentioned occurs in Mr. Haviland's collection from that 

 island, of which a complete set is present in the Calcutta Herbarium. No fruit has 

 been collected and as it has only 2 ovules it is not possible to predict with certainty 

 whether it may prove a Millettia or a second species of Pongamia, though the 

 probabilities are somewhat against its belonging to the latter genus. In any case 

 the writer is precluded from employing a distinctive name for the species since 

 Mr. Haviland has expressly requested that none of his probably new species shall 

 be named in Herb. Calcutta. The field-ticket of the specimen in question bears 

 the marks " c. k. q. g."
