nouveau genre Choristega v. T. avee deux especes: Ch. bahajeusis 

 (Korthals) v. T. et Ch. alveolata v. T. (St. alveolatum v. T.). 



Le genre ancien Lepostegeres a pour type le L. genufiißorus 

 Blume, et l'auteur y Joint une nouvelle espece de Borneo, L. Teys- 

 manni v. T. Le genre nouveau Choristegeres v. T. est seulement 

 represente par le Loranthus centiflorus Stapf, qui devient le Ch. ceti- 

 tijlorus v. T. 



Ainsi constituee, la famille des L£pidariac6es comprend trois 

 tribus, huit genres, dont cinq nouveaux, et dix-sept especes, dont 

 trois nouvelles. Toutes ces plantes habitent la Malaisie, et comme 

 le Gui croissent en parasites sur la tige des arbres, bien qu'abon- 

 damment pourvues de chlorophylle. J. Offner.

 1 — 113 with index. 



The first part of this important bulletin is concerned with forest 

 types and produets and is copiously illustrated with 28 plates and 

 maps. The author distinguished 10 t3^pes of forest, as follows: Lauan, 

 Lauan-hagachae, Yacal-lauan, Lauan-apitong, Tanguile-oak, Molave, 

 Pine, Mangrove, Beach and Mossy types. The first five are charae- 

 terized b)>' the presence of trees belonging to thej family Dipterocar- 

 paeeae which cover 75 percent of the virgin forest area and con- 

 taining approximately 95 percent of the total amount of Standing, 

 timber in the islands. Throughout the Molave type, the molave 

 (Vitex parviflora) is fairly well distributed, but many other tree 

 species are admixed, such as dungon [Tanielia sylvatica), supa 

 (Siudora supa), etc. The mangrove forest type is literally that of 

 the sea. A majority of the stand is composed of trees belonging to 

 the famil3 r Rhizophopaeeae. The Beach type is that of sandy 

 beaches with Pandanus, Barringtonia speciosa, Casuarina equiseti- 

 folia, as conspieuous elements. The Pine type is characteristic of 

 the highlands. In central and northern Luzon, Pinus insulans pre- 

 vails; in Mindoro, Pinus Me/kusii is found. The Mossy forest type 

 Covers 8 percent of the land area of the Philippines on the high 

 and very rough mountain regions. In this part, the uses of the 

 native woods are considered, as also the weight and hardness, lum- 

 bering, minor forest produets, etc. 



Part II deals with the prineipal forest trees of the islands. It 

 is illustrated by 103 plates of the tree species, which aecompany 

 descriptions of the forestal and botanic peculiarities of the native 

 forest trees. Photographs of bark and habit are helpful details of 

 the repert. Harshberger. 



Winkler, HL, Chlamydacanthus Lindavianus H. Winkl. — Eine 



neue Art einer bisher monotypischen Gattung. (Rep. 

 Spec. nov. IX. p. 523—524. 1911.) 



Die neue Art aus Deut seh- Ostafrika unterscheidet sich von 

 der typischen Chlamydacanthus Art durch höher verwachsene und 

 mehrblütige Brakteolen, die nicht zweispaltige, sondern scheiben- 

 förmige und nach der Mitte zu trichterartig vertiefte Narbe. Ferner 

 sind die Theken der vorderen Antheren ungleich und in verschie- 

 dener Höhe inseriert. Es sind nicht 2, sondern 4 Samen vorhanden. 



Die Diagnose der Gattung muss also in diesen Punkten erwei- 

 tert werden. \V. Herter (Tegel).
