Neither of the specimens belong to M. wmbellatum, Linn., and | am unable to say 
to which of the localities he gives the various specimens belong. He states that they 
grew in the Karroo between Olifants River and the Bokkeveld Berg, and in the Karroo 
beyond Hartequas Kloof. 
M. uncinatum, Thunb., ` Fl. Cap.,” p. 420. 
One sheet, containing four specimens, three of which belong to M. wncinatum, Linn.., 
Sp. Pl.” ed. 1, p. 483 (1753) ;. M. uncinellum, Haw., ~ Rev.,” p. 125 (1821). 
These specimens are identical with Rehmann No. 2844 (from Verkeerde Vley, in the 
Ceres Division). 
The foarth specimen is a scrap of M. villosum, L. (M. Eekloms, Salm Dyck, `` Mesemb..,’’ 
$ 49, fig. 5). evidently accidentally mixed with the other specimens. 
Thunberg collected JM. wneinatum on the Karroo between the Olifants River and 
the Bokkeveld Mountains. 
M. verruculatum, Thunb., “ Fl. Cap.,” p. 435. 
One sheet, containing three specimens, all belonging to different species, neither of 
which is M. rerruculatum, Linn. 
Thunberg gives two descriptions, and states in one (description a) grows in the 
Karroo between the Olifants River and the Bokkeveld, and the other (deseription G) at 
Hantam. 
The lower specimen on the sheet, which seems to fit description `` a,” has been marked 
“3” by Sonder, and quoted by him as being JM. veruculoides, Sond. But it is not the 
plant described by him under that name, his description having been made from a plant 
collected by Zeyher. Thunberg’s specimen is not determinable. 
The middle specimen on the sheet is M. glaucum, Linn. 
The upper specimen is different from either of the others, and consists of a piece of a 
stout, prostrate, leafy, purple stem without flowers. It is identical with Wolley Dod’s 
specimens Nos. 2420 and 3663 (from Lion’s Head, near Capetown), which I have not 
identified. | 
Besides these enumerated above, Thunberg’s Herbarium contains four sheets that 
are unnamed by Thunberg, one of them being named by Sonder. The following is my 
identification of these :— 
M. caninum, Lam., “ Encycl.,” Vol. II, p. 487 (1786). 
One sheet, labelled on the back as from Upsala Botanic Garden. 
M. noctiflorum, Linn. 
One specimen, labelled “ Caroo infra Bockland.” | 
A EE ee is without information on the sheet, may possibly be M. spectabile, 
Haw., “ Obs.,” p. 385 (1795). 
M. eee in op Pi. ed. N, p. 483 (1759). 
M. Ecklonis, Salm Dyck, `` Mesemb.,” § 49, fig. 5 (after 1836). 
One specimen, stated on the back of the sheet to have been collected at the Cape of 
Good Hope. 
It is correctly named M. Ecklonis by Sonder. which so exactly agrees with the original 
description of M. villosum under the name of “ Mesembr -yanthemum caule foliisque 
pubescentibus * in Linnaeus, “ Hortus Oliffortianus,” p. 216, as quoted in his `` Species 
Plantarum,” that 1 have no doubt whatever of its identity with that plant, although there 
is no specimen of M, villoswm in the Linnean Herbarium,
