 Fall von "Rhizanthie" aus Kamerun. [Paraphyadanthe Mildbr., a new genus of Flacourtiaceae. 

 An interesting case of "rhizanthy" from Kamerun.] Notizbl. Bot. Gart. Berlin 7 : 399-405. 

 Fig. A-0. 1920. — The new genus Paraphyadanthe, with two species and one variety, produces 

 flagelliform runners from the base of the trunk which extend to a distance of 10 meters or 

 more along the surface of the ground, bear scale-like leaves, and produce the flowers either 

 directly or at the summit of erect scaly branches. The vegetative portion of the plant is a 

 small tree, up to 9 m. high. The genus is closely related to Oncoba and Xylotheca. The fol- 

 lowing are the new species and variety described: P. flagelliflora, P. flagelliflora y&x. hydro- 

 phila, and P. coriacea. — H. A. Gleason.

 1920 (cont. from Jour. Bot. 57:91. 1919). — 3. Plantae Rogersianae. — V. Under the Legu- 

 minosae thirteen species, subspecies and varieties are treated, the following being new: Crota- 

 laria cataractarum Baker fil.. South Rhodesia; C. acervata Bak. fil., Belg. Congo; C. macro- 

 tropis Bak. fil., Belg. Congo; C. rigidula Bak. fil., North Transvaal; C. homalocarpa Bak. 

 fil., S. Rhodesia; C. longistyla Bak. fil., S. Rhodesia; C Harmsiana Taub. var. congoensis Bak. 

 fil., Belg. Congo; Indigofera gonioides Hochst. var. rhodesica Bak. fil., S. Rhodesia; I. dimidi- 

 ata Vog. var. laxior Bak. fil., Transvaal; and /. Burkeana Benth. form. All the new species of 

 Crotalaria belong to the section Eucrotalaria. The Leguminosae were elaborated by 

 Edmund Baker. Under the Compositae four species are treated of which the following are 

 proposed as new: Stoebe Mossii, Cape Colony; S. affinis, Cape Colony; Metalasia Rogersii, 

 South Africa. Under the Convolvulaceae notes are given on Merremia kentrocaulos Rendle 

 var. pinnatifida N. E. Br. In the Solanaceae, Solanum Rogersii is described as new. 4. Phyl- 

 lanthi ex Rhodesia species nova. Phyllanthus Eylesii is proposed as new. 5. Acanthaceae 

 Papuanae a cl H. 0. Forbes lectae. Nine species are listed and the n. comb. Graptophyllum 

 Gilligani (= Justicia Gilligani Bail.) is made. — K. M. Wiegand. 



2222. OSTERHOUT, Geo. E. A new Oreocarya from Colorado. Bull. Torrey Bot. Club 47: 

 211. 1920. — Oreocarya procera from Glenwood Springs, Colorado, is described as a new 

 species. — P. A. Munz. 



2223. Pennell, I'rancis W. Soil preferences of Scrophulariaceae. Torreya 20: 10-11. 

 1920. — Instead of the expression "potassic soil," used by the author in his published studies 

 of the Scrophulariaceae, "non-calcareous and non-magnesium soil" should be substituted. 

 The chemical composition of soils and its relation to plant-distribution demand the attention 

 of field-botanists. — J. C. Nelson.

 Jahrb. 56 (Beibl. no. 123) : 23-30. 1920 (cont. from Bot. Jahrb. 42:50-72. 1906).— Report 

 on grasses collected by Dr. A. Weberbauer in Peru, Ecuador, Bolivia, Argentina, Brazil, 

 etc. The following species, varieties and names are proposed as new: Stipa depauperata, 

 and vars. glabrata and humilis, S. Hans-Meyeri, S. Hieronymusii, S. pachypus, Oryzopsis 

 rigidiseta, 0. Neesii, (Piptatherum obtusum Nees), Piptochaetium laeve (Piptatherum laeve 

 Nees), Sporobolus mirabilis, Eragrostis carazensis, Dissanthelium minimum, Poa gymnantha,

2225. Radlkofer, L. Gesamtiibersicht uber die Sapindaceen Papuasiens. [Survey of 

 the Sapindaceae of Papuasia.] Under the general heading: C. Lauterbach. Beitrage zur 

 Flora von Papuasien. VII. Bot. Jahrb. 56 : 251-316. 4 fig- 1920. — The limits of Papuasia 

 are outlined, and it is noted that of the 14 tribes in the Sapindaceae only three are not rep- 

 resented, — Sapindeae, Koelreuterieae, and Cossignieae. Tribes Paullinieae and Thou- 

 inieae are mainly American, while Tribe Aphanieae is almost entirely Asian and Papuasian. 

 The range of the other tribes is given, together with the size and general distribution of the 

 noteworthy genera in each. The total number of genera represented is 26. Sixteen of these
