SPECIES OF MESEMBRYAXTHEMUM.

t> 



Since writing the aLovo , Mr. N. S. Pillans has called my attention to some 

 "Notes on M^semhnjanthemum''^ by J. Britten in the ' Journal of Botany' 

 for 1917, wliere, on p. 73, Mr. Britten also remarks that Af. Iceve^ Ait. and 

 ilA li^ve^ Tliunh. cannot he one and the same species, hut adds no information 

 tluit I have not already given in the ahove account. 



§ CORNICULATA. 



M. DlssiMlLEj N. E, Br. As the plant fi^i'urod and described as being 

 il/, raUdam^ Haw. by Salm-Dyck (from wliom both Sonder and Berger have 

 copied their descriptions) is a totally different species from the true M, validum 

 of Haworth (see p. 121) with solitar}^ yellow flowers having 17-20 stigmas, 



.-^ ■^ 



and belongs 



to quite a different group, I 



j)ropose the above change of 



name for it, the following being its synonymy : — AJ- dissimile^ N. E. Br. 

 M. validuni, Salin-Uyck, Mesemb. §15jfig, 8: Sonder in Fl. ('ap. voh ii. 

 p. -lOO : Berger, Mesenib, p, 138; fig. 2 4, III (copied from Salm-Dyck), not 



of Haworth. 



SoLFTii Afiiica. Locality and collector unknown. 



§ CRASSULINA. 



M, iN'VALTDU.Ar, JV, E, Br. A change of name for tlie plant wrongly 

 called 2L hicomptum in modern books. — J/, invalulvm^ N. E. Br. M, incomptum 

 (including yww. Eckhmis)^ Salm-Dyck, ]\Iesemb. § 5(), figs. 4 & 4/3 : Sonder 

 in Fh Cap. vol. ii, p, 451 : Berger, Mesemb, p. 73, not of Haworth, 



South Africa, Locality unknown. Probably introduced by Eclion, 



This is a plant with weak stems or branches 1--2 feet long, and is totally 

 unlike the true il/. incomjjtum of HaAVorth (see p. 131), 



Salm-Dyck wrongly quotes Burchell as the introducer of tliis plant, for 

 evidently some mistake has been made, as it is certainly not the same species 

 as Burcheirs plant, and I suspect that as the variety Ecklo)Us was introduced 

 by Ecklon, that which Salm-Dyck calls typical ]\E Uicompiwn was sent by 

 him aUoj and some mistake made as to the labels, which often happens in 

 larore trardens- I see no difference between the two plants represented 

 by Salm-Dyck on the two plates quoted "other than any two specimens of 

 one plant might show. 



§ CYMBIFORMIA. ^ 



L 



M. Lehmaxni, Eckl. ^ Zeyli. Since the pablication of my descrii.tion of 

 M. sexpartitum tlie plant has altered its character and become exactly like 

 M. Lehnannl^ so that it nmst be placed as a synonym o£ the latter. AAlieii
