This genus comprises the Buchnera viscosa Ait. and perhaps some other Cape plants 
which have been hitherto placed in Buchnera, without corresponding at all to any character 
given of that genus. It only differs from Nefflea in the glabrous stamina, and from my 
section Chaenostoma of Manulea, in the very short tube of the corolla and longer exserted 
stamina, thus forming the link that connects the Verbasceae with the Buchnereae. Ben- 
thani, MSS.

This genus must be confined to the M. muscosa, Br. The M. spathulata, Hook, must 
either be united to Peplidium or be considered as a separate genus. Bentham, MSS.

Calyx 5-sepalus sepalis parum inequalibus. Corollae tubus elongatus tenuis, post anthesin 
recurvus, limbus planus sub-bilabiatus. Stamina fertilia 2. Antherae biloculares. Cap- 
sula 4-valvis. — Species unica S. hispida: Herba perennis humilis rigida, foliis subpani- 
culatis margine revolutis, floribus axillaribus sessilibus. The genus is intermediate between 
Gratioleae and Buchnereae. The plant was gathered by Drummond at Apalachicola.

The specimens in Smith’s herbarium have the leaves by no means strictly opposite, and it 
appears doubtful whether the stipules that are assigned to this genus really exist.
