crowded ascending-spreading leaves 6-7 lines long and 1 line thick, which appear to have 
been nearly terete “and very obtuse at the apex, a and are described by Thunberg as `` scarcely 
trigonous. Like some other species from the same region, the dried leaves have numerous 
dot-like blisters formed by crystalline particles of some salt or lime. Pedicel terminal, 
solitary, bractless, about 5 lines long. Calyx 4-lobed, according to Thunberg, but the 
lobes cannot be EE seen on the specimen. The flower seems to be in a closed condition, 
and measures about 5 lines from the base of the. calyx to the tips of the apparently lax 
petals, which are white, according to Thunberg. 
M. fastigiatum, Thunb., “ Fl. Cap.,” p. 413. 
One sheet containing two good specimens, collected on very dry hills near the Olifants 
River, towards the ‘north, in the Van Rhynsdorp Division. 
De Candolle, and following him Sonder, and Berger have maintained the name 
M. fastigiatum, Haw., which was published in 1795, and given to the four-years older 
M. fastigiatum, Thunb. the new name of M. papulifer um, even overlooking the fact that 
Haworth had also long before bestowed a new name upon it. Thunberg’s name, however, 
must be maintained, and as no good description of the plant exists. the following is an 
account of Thunberg” s type aaa a 
_M. fastigiatum, Thunb., ‘Nov. Act. Acad. Leop.-Car. es ’ Vol. VUIL, ASE 
7 (1791). 
Ma erectum. Haw., Mis. . Nat.” p. 53 (1803). 
M. papuliferum, D. C., “ Prodr.,” Vol. HI, p. 448 (1828). 
An annual 14-23 inches high, and as dried, broadly obconic in outline and 2-3 inches 
in diameter across the flat top, densely covered with watery papillae on stems, leaves, and 
calyx. One specimen is divided at the base into two, and the other into three main branches, 
each of which at about half an inch above the base is divided into two or three branches 
1-3 inch long: each of these either bear one to three flowers at the apex or divide once 
more before ‘doing so, the whole forming a flat-topped cvme. All the branches thicken 
upwards in an obconic manner. The leaves have disappeared from the lower nodes, and 
the few that remain are much shrivelled, 5—7 lines long and 1 line thick; they seem to have 
been nearly terete, or perhaps more or less flattened above, obtusely rounded at the apex. 
The flowers seem to be nearly sessile or bat shortly pedicellate. Their structure | have 
not examined, but Thunherg deseribes the calyx as 5-lobed; the lobes as being ovate, 
obtuse, purple, and the corolla is snow-white. | 
I find that there are much larger specimens of this plant at the British Museum, 
collected by Masson. 
The plant later described as M. fastigiatum. by Haworth, requires to have a new 
name ; therefore, | propose for it that of—- 
M. plenifolium, NE Br. 
M. fastigictm, Haw., ` Obs.,” p. 210 (1795); not of Thunberg. 
M. filiforme, Thunb., “ Fl. Cap.,” p. 417. 
One specimen, collected at Hantam. 
This plant is not a Mesembryanthemum, but is a species of Galenia, and may therefore 
bear the following name : 
Galenia filiformis, N.E.Br. 
Mesembryanthemum filiforme, Thunb., `` Prodr.,” p. 89 (1800), and ` Fl. Cap..” p. 417. 
Aizoon microphyllum, Bartl., in `` Linnaea,” Vol. VIT, p. 541 (1832). 
This plant was left undetermined by Sonder, and it seems to be distinct from @alenia 
herniariaefolia, Fenzl., under which Sonder places Aizoon microphyllum as a synonym. 
It was evidently covered with minute watery papillae when alive, and the shrunk cells 
in some places have somewhat the appearance of pubescence, but I do not perceive any 
real hairs upon this or on (. herniariaefolia, sach as Sonder mentions in his Key to the 
species of Galenia.
