198 THE JOURNAL OF BOTANY 



T. jasminiflora are longer and protruding beyond the tube, and the 

 anthers narrow, very much acuminate ; finally, the styles and the 

 stigmas do not agree in shape. From the differences mentioned it 

 appears, then, that the identity of C. Engleri and T. jasminiflora 

 is impossible. Mr. Spencer Moore will be able to satisfy himself 

 when comparing the figure of C. Engleri — which I have since re- 

 examined and found correct in every detail — with the dissections of 

 the floral parts of T. jasminiflora as shown in Engler & Prantl 

 (Natiirl. Pflanzenfam. iv. 4, p. 81, fig. 29, F-H). I must object

the district of Mosambique, which the Matopos are generally 

 attached to (cf. Fl. Trop. Afr.), viz. C. racemosa Lour., zanzebaria 

 Lour., and 0. ibo Frohner. 



Another note of Mr. Spencer Moore refers to a specimen of 

 Oldenlandia collected in British East Africa by Kassner as n. 653 

 or 865,* and described by me as Oldenlandia Kdssneri. Having 

 learned since that the name 0. Kdssneri has been used for another 

 plant, I now propose to call my former O. Kdssneri 0. leptophylla. 

 At the same time 0. leptophylla cannot possibly be identical with O. 

 Wiedenmannii K. Sch. (not " Wiedemannii" as printed). 0. Wieden- 

 mannii, which Mr. Spencer Moore knew only ex descriptione, is a species 

 established by Schumann, who also recognized 0. leptophylla as a 

 new species, and had given it a special name. It seems very difficult 

 to believe that the same author should have published again as a 

 new species a plant formerly named and described by himself. In 

 fact, 0. Wiedenmannii and 0. leptophylla are species essentially 

 different : chiefly by the upper parts of the stem, the calyx and 

 ovary being rather densely hairy in 0. Wiedenmannii, completely 

 glabrous in 0. leptophylla ; also by the shape of the petals, different 

 in the two species : oblong and distinctly acuminate in 0. Wieden- 

 mannii ; broader, more ovate and rather obtusate at the apex in 

 0. leptophylla. I think there is no doubt left about the diversity of 

 the two species. 



A third note of Mr. Spencer Moore about Pentanisia crassifolia, 

 described by me, will perhaps prove to be better founded. I was 

 induced to create this species by its leaves being very thick, nearly 

 fleshy, remarkably different in that respect from all other species 

 of the genus so far described. As Mr. Spencer Moore now declares 

 that his P. sericocarpa shows the same quality, unfortunately not 

 mentioned by him in his original description, I think both species 

 identical, although a few small differences in the dimensions of the 

 floral parts seem to remain. 



[Dr. Krause is certainly correct in his view that Coffea Engleri 

 K. Krause is not the same plaut as Tricalysia jasminiflora Benth. & 

 Hook. fil. In fact, I now find that the specimens from Rhodesia 

 referred by me to T. jasminiflora (Bulawayo, Hand, 637 ; and 



* As for the number so far doubtful, Mr. Spencer Moore declares it to be 

 653, whereas the specimen of the Berlin Museum is distinctly 655. He is 

 right, then, in supposing that there is an error, but it is not with me.
