1442. Gagnepain, F. Barringtonia et Decaspermum nouveaiix. [New species of Bar- 

 ringtonia and Decaspermum.] Bull. Mus. His. Nat. [Paris] 26: 72-74. 1920. — Barringtonia 

 Eberhardtii, b. edaphocarpa, and Decaspermum cambodianum from southeastern Asia are 

 described as new. — E. B. Payson. 



1443. Gagnepain, F. Un genre nouveau de Composees, Blumeopsis. [Blumeopsis, a new 

 genus of the Compositae.] Bull. Mus. Hist. Nat. [Paris] 26: 75-76. 1920.— Blumeopsis is pro- 

 posed as a genus new to science and to it is assigned one species, B. Jlava {Blumeaflava DC.), 

 from southeastern Asia. — E. B. Payson. 



1444. Gamble, J. S. The Indian species of Mimosa. Bull. M sc. Inf. Kew 1920: 1-6. 

 7 fig. 1920. — Seven species of Mimosa are recognized as occurring in British India. These 

 species are contrasted by means of a key and figures illustrating the characteristics of the 

 leaflets. The following species are described as new to science: M. himalayana, M. Barheri, 

 M. Prainiana. — E. Mead Wilcox. 



1445. GoDFERT, M. J. Epipactis viridiflora Reich. Jour. Botany 58:33-37. PL 553. 

 1920. — This is supplementary to a paper in Jour. Botany 57: 37-42. E. viridiflora var. lepto- 

 chila Godfery is contrasted with E. latifolia All., which most continental authors consider a 

 mere form or var ety. In the first portion of the paper, differences in vegetative organs are 

 considered; and in the second portion differences in reproductive organs are taken up. The 

 root systems of the two are very different. Also the leaf arrangement is different; in E. viri- 

 diflora it is distichous, while in the other species the leaves are in a six-ranked rosette. 

 Many differences were found in the flowers, most of which are llustrated in the plate. These 

 differences lie in the form of the top of the ovary, the sessile or stalked acute or obtuse anther, 

 and the projection of the pollinia. The rostellum in one species is minute and withered; 

 in the other, large and persistant. The more conservative nature of floral variation is 

 noted; hence the importance of the differences mentioned. The relation of structure to repro- 

 duction in Anacamptis pyramidalis is taken as an example of the above statement, and out- 

 lined. These differences between E. viridiflora and E. latifolia are correlated with remarkable 

 functional changes. E. latifolia is pollinated by wasps, and the pollen is not friable, but is 

 carried as a pollinium. Self-fertilization seems impossible. In E. viridiflora var. lepto- 

 chila the viscid gland is reduced and inoperative, and "fertilization" by insects does not occur, 

 or at least is rare. It is shown how the contents of the anther slide down onto the viscid 

 surface of the stigma, producing self-fertilization. In E. viridiflora var. dunensis, the pollen 

 is very friable even before the flower opens. E. viridiflora was originally fertilized by insects, 

 but has lost that function. Muller believed that cross-fertilization in E. viridiflora occasion- 

 ally occurred, due to aphids; but the author thinks this very exceptional. MtJLLBR studied 

 the two species most minutely, and said that we have here two form cycles which differ by 

 thoroughly essential characters, and have the same claim to be considered distinct species 

 as any two species of a genus.— if. M. Wiegand. 



1446. GuiLLAUMiN, A. Contribution a la Flore de la Nouvelle-Caledonie. [Contribution 

 to the Flora of New Caledonia.] Bull. Mus. Hist. Nat. [Paris] 26: 77-84. 1920 In continua- 

 tion of previous simila;r lists, species belonging to many families are listed, and various col- 

 lections of them are cited with the collectors' numbers and stations at which they were taken. 

 The following species are described as new: Utricularia canacorum Pellegrin and Litsea 

 ripidion. — E. B. Payson. 



1447. Hayata, Bunzo. Icones Plantarum Formosanarum nee non et contributiones ad 

 fioram Formosanam. [Icones of the plants of Formosa, and materials for a flora of the island, 

 based on a study of the collections of the botanical survey of the Government of Formosa.) Vol. 

 IX. 155 p., 8 pi., 55 fig. Bureau of Forestry, Government of Formosa: Taihoku. March 25. 

 1920.— The present volume continues the results of studies on the formosan flora and includes 

 the families Ranunculaceae to Araceae, arranged in the sequence of Bentham and Hooker. 

 The following new species and varieties are proposed: Clematis garanbiensis, Illicium leucan-
