StECiES OF mese:\ibuyanthemum. 



121 



M. YALIDUM, Haxv. Branches stout, rigid, decumbent. Leaves long, palo 

 green, with a rough margin. Flowers subternate, with the keels of the 

 bracts entire. Petals rosy, with a red mid-line. ~ .lA validum^ Haw. in Phil. 

 Mag. 1826, p. 329. 



South Africa. Locality unknown^ introduced by Bowie. 



This species is entirely omitted from tijo monograph of Sender and of 

 Berger^ because they have i^oth ct^pied the unaccountable error made by 

 Salni-Dyck^ who figured and described a totally different plant with solit.ary 

 yellow flowers as being the d/, validum of Hawortli, which, although there is 

 not a drawling of it at Kew, is evidently, as Haworth states, closely allied to 

 M. Tigidlcaide^ Haw, and not in the least like the plant figured and described 

 by Salm-Dyckj Sender, and Berger under that name (see M. dissimile.ls. E. 

 Br., p. 105). In comparing M, validum with M. rigidiccudey Haworth states 

 that it differs in having shorter, more contiguous and more erect branches, 

 paler leaves that are always shorter (not sometimes longer) than the inter- 

 nodes, entire bracts not lacerate on the back^ and fewer, less pedunculate 

 flowers. 



§ SPINULIFEEA. 



M. VIGILANS, L. Bolus. Mrs* Bolus desires that the above name should 

 replace that of M, hesperantimm for the Bechuanaland plant described by her 

 in 1915 under that name, because the same name had been used by Dinter 

 and Berger in 1914 for a A^ery different species belonging to the section 

 BolahrifoUa, Therefore its synonymy will be : — J/, vigilans^ L. Bolus. 

 M. hespcrauthum^ L. Bolus in Ann. Bolus Herb. vol. i. p. 190 (1915), not of 

 Dinter and Berfjer. 



Bechuanaland. Gaberones, Rogers, 



§ TKICHOTOMA. 



M. MACKOiinizuM, 7/ai6\ This 'name Avas published by Haworth in 1826, 

 and was changed to M. m^garJnzitm by Don in 1834^ because another species 

 had been described by De Candolle under the name of AL macrorldzum^ and 

 all authors have subsequently upheld Don's name. But Haworth's name 

 was published two years earlier than that of De Candolle, and therefore must 

 be restored and another name given to the plant described by De Oandolle as 



r)ne^ N. E. Br., 



M, macrorldzum^ for which I propose that of M. napifor)ne^ 



see p, 110. 



The synonymy of Elaworth's plant will therefore*be as follows :~M. macro- 

 rldzum Haw. in PhiL Mag. 1826, p. 331 : Salm-Dyck, Mesemb. § 49, 

 fig. 3, M, megarhizitm^ Don, Gen. Syst. vol. iii. p. 145 (1834) : Sender in 

 PI. Cap. vob ii. p. 441 : Berger, Mesemb, p. 101.
