1. MESEMBBYANTHEMUM, Linn. ; Benth. et Hook. f. 

 Gen. Plant, i. 853. 



Calyx-tube adnate to the ovary ; limb 5-(l-8-)lobed, usually un- 

 equal. Petals oo, linear, inserted in the calyx-tube. Stamens oo, 

 multiseriate. Ovary inferior 5- (4— 20-)celled; styles as many as cells, 

 longitudinally stigmatose ; ovules oo. Capsule dehiscing- loculicidally 

 at the apex ; seeds' minute. — Herbs or frutescent, erect or procumbent, 

 leafy, fleshy. Leaves usually opposite, simple^ thick and fleshy, very 

 various in form; exstipulate. Flowers conspicuous, white, yellow or 

 rose. 



A large genus, principally South African, with a few scattered members in Austral- 

 asia and northwards to the Mediterranean. 



Two forms, or perhaps two species of Mesembryanthemum, are in the Kew Herbarium, 

 collected by Schimper in Abyssinia, but I prefer at present not to attach names to 

 them. I hey are both low herbs with branching woody 6tock and strongly papillose, 

 trigonous, or cylindric-trigonous leaves. Flowers in one form distinctly pedunculate, 

 with obviously unequal calyx-lobes (No. 1783 and part of 788); the other with subses- 

 sile flowers (No. 503). Eichard also notices two species, which he does not describe at 

 length nor name, collected by Petit (Fl. Abyss, i. 316), one papillose, the other not. 



1. M. dimorphum, Welw. mss. (§ Upapulosa, probably section 

 Juncea). Glaucous glabrous decumbent tortuous herb, at length, after 

 3 or 4 years, rigid pubescent with much reduced leaves, copiously 

 flowering- ; decumbent branches terete, nearly the thickness of a goose- 

 quill. Leaves opposite, subterete, 1st and 2nd year f-1 in. long-, 

 narrow-linear when dried ; of older plants very narrow tortuous, J-^ 

 in. Flowers small whitish terminating short unilateral leafy ramuli. 

 Calyx-lobes subequal, rotundate or ovate, obtuse, nearly as long as 

 petals. Styles 5. Capsule 5-valved.

2. M. dactylinum, Welw. mss., (§ Epapulosa, Calamiforme) . Small 

 very succulent annual herb 1-3 in. high, simple or with a short forking
