The ovate-cordate leaves have a very regularly crenate margin and do not 
show any trace of lobes. The surface of the lamina is somewhat wrinkled. 
The tomentum is composed of few-raved strigose hairs, which are especially 
well developed on the upper parts of the peduncles. M. Fiebrigii appears to 
be the nearest ally of this species ; it does not appear to be nearly related 
either to M. Purdiaer or to M. parnassiwfolium as has been suggested.

This plant was referred by Grisebach l с. to Sida parnassicfolia, В. lobulata, 
Wedd., with the added diagnosis “foliis circumcirca duplicato- v. inciso- 
crenatis.” It differs from M. nubigena in its more or less orbicular leaves, 
cordate at the base, in the absence of well-marked lobes, and in the broad 
blunt erenulations of the margin. M. Fiebrigii appears to be related to 
M. betoniewfolium, and it is possible that the latter may eventually prove to 
be a varietal form of M. Fiebrigi. In M. betonicæfolium, however, the leaf- 
erenulations are much more numerous, the sepals more ovate, and the 
involueral braets are broader. The two species are also separated on the 
character of the carpels.
