534. ScHELLENBERG, G. Connaraceae africanae. III. [Connaraceae of Africa. III.] 

 Bot. Jahrb. 55:436-456. 1919. — The paper is made up of the descriptions of new species, 

 and the designation of new combinations found necessary in the preparation of a mono- 

 graph of the famil}' soon to appear in "Das Pfianzenrcich." The new species are: Cnesiis 

 liberica, Liberia; C. Dinklagei, Liberia; C. cinnabar ina, Kamerun; C. longiflora, Lagos; 

 C. leucantha Gilg, Kamerun; C. calantha, Kamerun; C. gabunensis, Gabun; C. Zenkeri, 

 Kamerun; C macrophylla Gilg, Kamerun; Manotes Tessmannii, Gagun; M. Zenkeri Gilg, 

 Nigeria, Kamerun, etc.; M. rosea, Gabun and Kamerun; M. rubiginosa, Angola; M. 

 Soyauxii, Loango; Paxia calophylla Gilg. Kamerun; P. Zenkeri, Kamerun; P. cinnabarina, 

 Kamerun; P. lancea, Kamerun; Byrsocarpus Ledermannii, Kamerun; B. tomentosus, Dutch 

 East Africa, Rodesia, etc.; B. papillosus, Kamerun; Santaloides urophyllum, Kamerun; Jolly- 

 dora glandulosa, Kamerun. New combinations are as follows: Cnestis Mannii {Connarus 

 Mannii Baker); C. pseudoracemosa {Connarus pseudoracemosus Gilg); Roureopsis Thonneri 

 {Rourea Thonneri De Wild.); Spiropetalum Reynoldsii {Connarus Reynoldsii Stapf); Santa- 

 loides gudjuanum {Rourea gudjuana Gilg); S. splendidnm {Rourea splendida Gilg); S. baman- 

 yense {Rourea bamanganense De Wild.). Notes are given on Paxia my riantha (Baill.) Pierre, 

 Byrsocarpus orientalis Baill., B. Poggeanus (Gilg) Schellenb., and B. maximus Bak. — K. M.

535. ScHELLENBERG. G. Ucber die Connaraceen-Gattung Jaundea Gilg. [On the genus 

 Jaundea Gilg of the family Connaraceae.] Bot. Jahrb. 55: 457-463. 1919.— Gilg described 

 in 1895 a genus Jaundea based on a plant which he named J. Zenkeri collected by Zenker 

 near the station Jaunde in Kamerun. The new genus was included in Natur. Pflanzenfam. 

 where in one place it was spelled Yaundea, an unjustifiable spelling of the word. Gilg 

 admitted later that he was deceived by the young inflorescence and the position of the 

 anthers in the Zenker material, and that his name should be a syrtbnym of Rourea pseudo- 

 baccata. Later Schellenberg in his inaugural dissertation made Jaundea a section of 

 Byrsocarpus; but he now recognizes it as a genus containing the original plant of Gilg, but 

 having different characters and limits. As thus understood it contains a portion of the 

 species originally ascribed by Schellenberg to Jaundea as a section of Byrsocarpus. The 

 unimportance of certain biological characters from a taxonomic point of view is discussed, 

 as for instance the appearance of the flowers with or after the leaves. The nervation of the 

 leaf and the type of inflorescence are important in separating Jaundea and Byrsocarpus. A 

 diagnosis of the genus is given and the characters which separate it from Byrsocarpus are 

 tabulated. The species and forms included are as follows: Jaundea Baumannii {Rourea 

 Baumannii Gilg); J. congolana; J. Leskrauwaetii {Rourea Leskrauwaetii De Wild.); J. monti- 

 cola {Rourea motiticola Gilg); J. Oddoni {Rourea Oddoni De Wild.); /. pseudobaccata {Rourea 

 pseudobaccata Gilg); /. pubescens {Connarus pubescens Baker); J. pubescens iorma, glabrala. —

536. Schlechter, R. Die Gattung Cochlioda Ldl. [The Genus Cochlioda Ldl.] Orchis 

 13: 3-10. 1919.— (Concluded.) An extensive generic description is followed by a key to the 

 five recognized species of Cochlioda. Specific descriptions, synonomy, and the citation of 

 specimens are included. Symphyglossum is described as a genus new to science, and to it are 

 assigned the following species: S. sanguineum {Mesospinidium sanguineum Rchb. f.) and 

 S. strictum {Cochlioda stricta Cosn.). — E. B. Payson. 



537. Schlechter, R. Noch eimnal iiber Epidendrum pentotis Rchb. f. und Epidendrum 

 Beyrodtianum Schltr. [Again concerning Epidendrum pentotis Rchb. f. and Epidendrum 

 Beyrodtianum Schltr.] Orchis 13: 27-29. 1919.— The difference between these two similar 

 species is reiterated, and drawings are presented to show the floral structure of E. pentotis 

 Rchb. i.—E. B. Payson.
