Hygrophila Vanderystii, Justicia fistulosa, and Rhinacanthus minimus. (2) Vaupelia A. 

 Brand. This, a genus of Borraginaceae, was removed by Brand from the Cynoglosseae 

 to the Lithospermeae. The close relationship of Vaupelia and Cystistemon Balf, f. was 

 also noted by Brand. As now understood Vaupelia, ranging from Somaliland to Angola, 

 contains six species. In the "Flora of Tropical Africa" V. macr anther a was wrongly merged 

 in Medxisa. A seventh and new species, V. hispidissima from Angola, is added in the 

 present paper. It is related to V. Medusa Brand. — K. M. Wiegand.

 States with special reference to the economic species. U. S. Dept. Agric. Bull. 772. 307 p., 

 20 pi., 174 fig. Government Printing Office: Washington, 1920.] TorreyaZO: 84-88. 1920.— 

 In several respects this book marks an advance over our previous knowledge. A new sequence 

 of tribes is proposed, by which the bamboos are placed first, as showing the least differentia- 

 tion in floral structure, followed by the tribes Poatae and Panicatae. The tribes Oryzeae 

 and Nazieae are placed with the Poatae. A new tribe, Zizanieae, is cut off from Oryzeae 

 on the basis of the unisexual spikelets. Munroa is placed with the Chlorideae. THodia is 

 restored. The name Aira is taken up for Deschampsia, and Aspris is substituted for Aira. 

 Agrostis alba L. becomes A. palustris Huds., and A. alba var. vxdgaris Thurb. becomes A. 

 capillaris L. The synonj^my is complete for all generic names based on American species. 

 The reason for selecting the species taken as the type is stated in all cases. Each genus is tech- 

 nically described, and all economic species mentioned. With two exceptions, all the illus- 

 trations are new. One new species (Epicampes patens) is described, and 14 new combinations 

 are formally made. — J. C. Nelson.

1472. Pennell, Francis W. Scrophulariaceae of the central Rocky Mountain states. 

 Contrib. U. S. Nation. Herb, 20: 313-381. 1920.— This paper, the first of a series, discusses 

 the genera Verbascum, Linaria, Collinsia, Scrophularia, Chionophila, and Penstemon, as 

 represented in the central Rocky Mountain region, including Wj'oming, Colorado, Utah, and 

 Idaho east of the 113th meridian. It is introduced by a description of the physical features 

 of the area and a list of localities at which specimens have been collected by Dr. Pennell. 

 Full descriptive keys are given in genera of more than one species, and a list of specimens ex- 

 amined is given under each species. The paper is largely taken up with a revision of the
