148. Godfrey, M. J. Epipactis viridiflora Reich. Jour. Bot. 57:37-42. 1919.— E. viri- 

 iiflora Reich, var. leptochila is described as new. The validity of E. viridiflora, E. violacea, 

 and E. latifolia as species is pointed out, through a very detailed side by side comparison of 

 characters. Interesting notes on the pollination and hybridization are given. The var. 

 leptochila is compared with forma dunensis of Wheldon and Travis and forma vectensis of Rev. 

 T. Stevens. The intermediates may be of hybrid origin, and therefore would not invalidate 

 the specific distinctness. — K. M. Wiegand.

150. Hutchinson, J. Primula chasmophila. Balf. f. Curtis's Bot. Mag. IV, 15: PL 

 8791 (colored). 1919. — A new species for the name of which Professor Balfour is responsible.

 Cystisus proliferus var. palmensis Christ, and "Gacia," C. stenopetalus Christ, as fodder 

 plants, and incidentally gives a synoptical summary of these species and their immediate 

 allies. Five species are characterized; one of these, Cystisus Perezii, endemic to the islands 

 of Grand Canary and Hierro, is new to science. C. proliferus var. palmensis Christ is raised 

 to specific rank. — J. M. Greenman. 



152. Hutchinson, J. Taxotrophis and Balanostreblus. Bull. Misc. Inf. Kew 1918: 147-

 title, and also presents a revision of the species. Seven species of Taxotrophis are recognized, 

 and of these T. caudata, T. laxiflora, and T. Balansae of India are new. Balanostreblus is 

 monotypic, being represented by one species, B. ilicifolia Kurz, from Burma. — /. M.

 a second, //. pilosa, is a new combination in this genus. — J. M. Greenman. 



154. Hutchinson, J. Cordia Myxa and allied species. Bull. Misc. Inf. Kew 1918: 217- 

 222. 3 fig. 191S. — A brief historical account is given of Cordia Myxa L. and the two allied 

 species C. obliqua Willd. and C. crenata Del., supplemented by a full bibliography and dis-

 sipes Wall. var. cholaense, Chola Valley, East Sikkim;*S. dasyphyllum, L. var. Suendermanni, 

 Spain; S. rubroglaucum, Yosemite Valley, Calif.; »S. anoicum, origin not known; S. Mairei,

157. Prain, D. The genus Chrozophora. Bull. Misc. Inf. Kew 1918:49-120. 191S.— A 

 detailed history of the Euphorbiaceous genus Chrozophora is given, and this is followed by a 

 synoptical revision of the species. The genus is widely distributed in the Old World and, as 

 at present defined embraces eleven species and several varieties. — J. M. Greenman.
