NOTES ON SOME TROPICAL AFRICAN RUBIACEiE 115 



of noticing a few oversights which have crept into the memoir in 

 question. The citations are given in order, 



Oldenlandia pedunculata K. Schum. & K. Krause has already 

 been described as 0. prolixipes S. Moore (I.e., p. 351). 



0. Kaessneri K. Schum. & K. Krause. The locality for this is 

 Sultan Hamoud (not lt Hamond," as printed), and the number is 

 given as 665. The only specimen of the genus from this place is 



referred by me (/. c. p. 350) to 0. Wiedemanni K. Schum., ex descrip- 

 tione, and as this specimen answers to Dr. Krause's description, and 

 its number is 653, it is clear that there is an error in the citation 

 of the number. I have examined the plant again, and still find it 

 to agree with the description, though, as Dr. Krause has access to 

 the type, he is better able to elucidate the point than I am. Perhaps 

 he will kindly look iuto the matter again. In any event the name 

 O. Kaessneri has already been used for Kassner 957 (/. c, p. 249). 



Randia congestiflora K. Krause is R. micrantha K. Schum. 

 var. Zenkeri S. Moore in Journ. Linn. Soc. xxxvii. p. 304. The 

 plant seems to me to be much more like R. micrantha than R. 

 sphcerocoryne K. Schum., with which Dr. Krause compares it. 



Pentanisia crassifolia K. Krause. This I cannot think distinct 

 from P. sericocarpa S. Moore. Dr. Krause gives as the points of 

 difference between the two, the form, size, and texture of the leaves, 

 and the length of the flowers. But the lower leaves of the single 

 specimen of P. sericocarpa are almost exactly, judging from the 

 description, as those of P. crassifolia, only a little smaller, while 

 the upper ones are narrower indeed, though almost as long (the 

 longest, I find, measure 3-5 cm.). As regards the texture of the 

 leaf, that I unfortunately did not record ; the leaves are distinctly 

 fleshy. Then P. crassifolia is said to have corollas with a tube 

 1*0-1 -8 cm. long., and my measurement for P. sericocarpa is 1-0 cm, 

 Lastly, the lobes of the corolla of my species are 4-5 mm. in length, 

 while those of Dr. Krause's are only 2-0-2*5 mm. ; but it should be 

 remembered that my measurement was taken from corollas expanded 

 after thorough soaking, and, moreover, I find that in the dry state 

 the lobes of corollas just opening measure only 2-5 mm. Both 

 specimens were found at Salisbury, Rhodesia, by Dr. Rand and 

 Professor Engler respectively. 



Plectronia microterantha K. Schum. & K. Krause has already 

 been described under the name of Canthium pseudoverticillatum 

 (I. c. p. 352). It is founded on Kassner 883. 



P. longistaminea K. Schum. & K. Krause is C. Kaessneri S. 

 Moore (/. c. p. 351). 



Coffea Engleri K. Krause. A figure is given of this ; it is un- 

 doubtedly Tricalysia jasminiflora Benth. & Hook. f. Miss Gibbs, 

 who found the plant in the same place, viz. the Matopos, where it is 

 abundant, drew my attention to this oversight. I believe there is 

 no Cojfea native to the Matopos ; at least Miss Gibbs, who botanized 

 there with such success in 1905, did not come across one. 



Pavetta lasiorhachis K. Schum. & K. Krause {Zenker 2259 and
