Prain, D., Thespecies of Dalbergia of South-Eastern Asia. 

 (Annais of the Royal Botanic Garden, Calcutta. Vol. X. Part 1. 

 1904. p. I— 111, 1— IV and 1 — 114. Plates 1—91.) 



After an introductory preface the author first gives an historical 

 review of the delimiitation of the genus Dalbergia; this is foUowed 

 by a sketch of the diverse attempts at classifying the species of the 

 genus. The authors main subdivisions are as foUows: 



Subgen. I.: Sissoa: Vexilli lamina erecta; alae basi cuneatae 

 rarius truncatae, rarissime subhastatae; carinae petalis cuneatis vel 

 hastatis; stylo crasso, cylindrico, saepius brevissimo; staminibus ad 

 norman monadelphis. 



§ I. Triptolaemea: Flores minuti, saepius minutissimi; bracteolis 

 infra calycem saepius persistentibus vel subpersistentibus; inflore- 

 scentia saepe dichotome cymosa; petalis omnibus ungue brevibus; 

 stylo semper brevissimo (D. Albertisii Prain, D. parviflora Roxb. etc.). 



§ 2. Podiopetalum: Flores parvi, nonnunquam minuti, bracteolis 

 infra calycem deciduis vel caducis; inflorescentia cymosim panicu- 

 lata; petalis omnibus ungue longioribus; stylo crasso cylindrico, 

 rarissime perbrevi (D. confertiflora Benth., D. Sissoa Roxb. etc.). 



Subgen. 11.: Amerimnon: Vexilli lamina reflexa vel refracta; 

 alae basi hastatae vel sagittatae; carinae petalis hastatis; stylo elon- 

 gato tenui. 



§ 3. Endospermum : Vexillum plus minus refractum; petalis 

 omnibus ungue angustatis; staminibus ad normam monadelphis; 

 stylo subulato D. rostrata Grab., D. congesta Grab.). 



§ 4. Miscolobiutn : Vexillum reflexum vix tamen refractum; petalis 

 ungue vexillo cuneato excepto angustatis; staminibus ad normam 

 monadelphis; stylo subulato vel cylindrico (D. veliitina Benth., D. 

 oblusifolia Prain etc.). 



§ 5. Dalbergaria: Vexillum reflexum vix tamen refractum; pe- 

 talis ungue vexillo cuneato excepto angustatis; staminibus ad nor- 

 mam isodiadelphis; stylo cylindrico vel subulato. fZ). senV^a G. Don, 

 D. Balansae Prain etc.). 



Further sections are devoted to a discussion of the validity of 

 the name Dalbergia, which is considered as being the only one 

 applicable and covering the whole ränge of the species, and of the 

 distribution of the Asiatic species of the genus. The latter subject 

 is dealt with in some detail and ülustrated by tables and diagrams. 

 The section Triptolemea is mainly represented in Malaya, both 

 China, India and Indo-China having few members of this 

 group; Podiopelaliim has no representatives either in Malaya or 

 Papuesia, only one in India (D. Sissoo), three in China and 

 four in Indo-China. Endespennnm is the most widely spread of 

 all the sections, one species (D. toria) occurring in every province; 

 Miscolobiuin is chiefly 1 n d o - Chin ese, no representatives occurring 

 in Pap u asia. Dalbergaria attains its maximum distribution in 

 Indo-China to the east of theirrawady, where 13 (9 endemic) 

 species are to be met with. 



The greater portion of the paper is occupied with specific de- 

 scriptions, amongst which the foliowing new names occur; D. Mimo- 

 sella Prain (= D. lanceolaria Nav. and Fernand.); D. fusca Pierre 

 MSS. in Herb. Pierre (very near D. cultrata Grab., but with smaller 

 leaflets, persistently adpressed-pubescent beneath); D. Hoseana Vx-äXw 

 n. sp. (nearest D. malabarica Prain, but with fewer and thinner 

 leaflets and calyx-teeth much shorter than the tube); D. Fierreana 

 Prain n. sp. (with densely tawny-pubescent young branches and
