MESEMBRYANTHEMUM, L. 
M. acinaciforme, Thunb., “ Fl. Cap.,” p. 422. 
This name appears in both Thunbere’s `` Prodromus” and his ` Flora,” but no 
specimen exists in his Herbarium representing that name as used by him. There is, 
however, a specimen named * M. forficatum”’ by Thunberg, which is the true M. acinaciforme, 
Linn., and that name is also written upon the sheet as `` acinaciforme, Mus.” 
M. albidum, Thunb., “ Fl. Cap.,” p. 423. 
The specimen consists of two well-preserved flowering branches of JM. albidum,. L. 
The locality of this species is not mentioned.

Thunberg collected this near the Sundays River in Uitenhage Division, and his 
specimens are identical with those of MacOwan, `` Herb. Austr. Afr.” (1873) from near 
Grahamstown. It is somewhat remarkable that this very distinct plant has not previously 
been identified with Jacquin’s excellent figure.
