 (Journal of Botany. Vol. XLV. N«. 531. p. 114—116. March 1907.) 



In a recent memoir by Dr. K. Krause (Engler's Bot. Jahrb., 

 39, p. 516—571), in which a number of Tropical African Ritbiaceae 

 were described, certain publications of the author's (Journ. of Bot. 

 1905, p. 249 and 350 et seq.; Journ. Linn. Soc, 37, p. 298 et seq.) 

 were overlooked. This necessitates alterations as foUows: Oldenlandia 

 pedunctdata, K. Schum. and K. Krause = O. prolixipes S. Moore;

 Randia congestißora Krause = R. micrantha K. Schum. var. Zenkeri 

 S. Moore; Pentanisia crassifolia K. Krause is regarded as not distinct 

 from P. sericocarpa S. Moore; Plectronia niicroterayitha K. Schum. 

 and K. Krause = Canthium pseudoverticillatum \ P. longistaminea 

 Schum. and Krause = C. Kaessneri S. Moore ; Coffea Engleri Krause = 

 Tricalysia jasminiflora Benth. and Hook, f.; Pavetta lasiorhachis

Pearson, H. H. W., Notes on South African Cycads. 1. 

 (Transactions of the South African Philosophical Society. Vol. XVI. 

 Part. 4. p. 341—354. Plates VI— VIII. 1906.) 



This paper deals with the natural history of four species of 

 Cycads, viz. Encephalartos Friderici Guilielmi Lehm., E. Altensteinii 

 Lehm., E. villosus Lehm, and Stangeria spec, and the author sum- 

 marises his results as foUows. Subterranean branching is a marked 

 feature of Encephalartos Friderici GuilieUni and Stangeria spec, and 

 plays a part in vegetative reproduction. The cones are lateral in 

 Position in E. Friderici Guilielmi and E. Altensteinii, the growth of 

 the stem in both cases being monopodial. In the former species, 

 which is subject to strong insolation, cones are much more abundant 

 than in either of the other species of Encephalartos, both of which 

 are shade-plants (esp. E. villosus). In E. Altensteinii plants more or 

 less exposed to sunshine not infrequently bear cones, but the latter 

 are rarety, if at all, found on plants in dense shade; the same 

 possibly applies to E. villosus. In E. Altensteinii branched specimens 

 seem to occur only in illuminated situations, and usually, if not 

 always, near water. There is a distinct probability that entomophil}' 

 occurs in E. villosus, whilst in Stangeria the position of the cones 

 points to the inefficiency of the wind as a pollinating-agent.
