As the above described plant must take precedence for the name M. ovatum; that in” 
Thunberg’s Herbarium now bearing that name requires to be renamed, and as I find it 
to be identical with a plant described by Berger, the following will be its synonymy :— 
M. Haeckelianum, Berger in “ Engler Bot. Jabrb..” Vol. XLV. p. 224 (1910). 
M. ovalum, Thunb., ` Fl. Cap.,” p. 417 (1828), not of ` Nov. Act. Acad. Leop.-Car- 
Kphem.,”’ Vol. VIL, Append., p. 8 (1791). 
M. elongatum, Eckl. & Zey., ` Enum. Plant. Afr. Austr.,” p. 321 (1836), and in 
‘ Linnaea,” Vol. XIX, p. 658 (1847). 
M. angulatum var. ovatum, Sond. in `` Fl. Cap., Vol. TH, p. 454, partly (1862). 
Root-stock perennial. Stems probably annual ascending or perhaps prostrate with 
ascending branches, up to 18 inches long and 14 line thick, angular, glabrous, and apparently 
smooth, with internodes up to 2 inches long. Leaves opposite, 313 inch long, 3-9 lines 
broad, lanceolate or ovate, acute, tapering into a petiole at the lower third, entire, glabrous, 
apparently smooth, fleshy. Flowers solitary in the forks of the stems or axillary, Pedicels 
11 inch long. moderately stout, glabrous, bractless. Calyx very unequally 4-lobed, the 
two larger bes G6—10 ae long and 3-4 lines broad, lanceolate or ovate- lanceolate, acute, 
leaf-like, the two smaller 45 lines long, with a membranous ovate basal part and a subulate 
point. Petals numerous, aie 6 ies long and }—} line broad. Stamens numerous. 
Style 1-3 line long, stout : stigmas 4, short, apparently flat, acute. 
Valley and hills of the Zwartkops River, in the Uitenhage Division, Zeyher No. 2624, 
and without locality, but probably from the same region, a flowerless specimen in Herb. 
(Thunberg). 
Sonder in ` Fl. Cap.” p. 454, quotes the plant named JZ. oratwm in Thunberg’s 
Herbarium and Zeyher No. 2623 under M. angulatum var. ovatum as both being the same 
plant, whereas they are entirely different, the JM. ovatum, Herb. (Thunberg), being 
M. Haeckeliamuan just described, and Zevher No. 2623 being M. angulatum, Thunb, 
M. papulosum, Linn. f., ` Suppl...” p. 259 (1781). 
One sheet containing three specimens in fruit. This species is not mentioned in 
Thunberg’s ` Flora Capensis,” nor is there any indication of locality on the back of the 
sheet. But as it was described by Linnaeus fil. from a plant cultivated in Upsala Botanic 
Garden, it may have been raised from seed obtained from these fruiting specimens, or these 
specimens may have come from Upsala Garden; and as they accurately agree with the 
description of Linnaeus fil., they must be accepted as the type of the species, for there 
is no specimen of the plant among those from the Herbarium of the younger Linné, and 
as he described many species from Thunberg’s specimens, these may even possibly be those 
from which he described. He quotes, however, M. Aitouis, Jacq. as a synonym of 
M. papulosum. This is an error, for M. Aitouis has angular (not terete) stems, quite different 
leaves, straight (not deflexed) pedicels, and broad obovate (not subulate) tips to the calyx- 
lobes. JM. Aitouis is also an eastern species from the Uitenhage Division, whilst 
M. papulosum grows near Capetown, for it is identical with Wolley Dod No. 2864, from 
the shore between Sea Point and Camps Bay. The plant is an annual, covered with large 
papillae, and is well marked by the peculiar curvature just below the calyx of the 6-8 lines 
long pedicels, causing the flowers to nod. The petals are small and yellow, `` half as long 
as the shorter calyx-lobes.” 
M. pinnatifidum, Thunb.. ` Fl. Cap.,” p. 427. 
Two sheets; one contains a specimen from Upsala Botanic Garden. The localities 
given by Thunberg are Mountains of Roode Zand, near Tulbagh Waterfall, and on the 
Paardeberg. All belong to 
M. pinnatifidum, Linn. £., “Suppl...” p. 260 (1781).
