No. 2. Originating at the very base of the first one, and oppo- 

 site or oblique to it. 



Streptocarpus Dunnii, Hook. f. 



Cotyledons perfect and normal after germination, rotund, entire, 

 growing until they reach a certain size (still very small) when one 

 ceases and the other develops into a large leaf as described below. 



Stem very short, fleshy, and scarcely distinguishable from the 

 base of the leaf. 



Leaf developed from one of the cotyledons, solitary, radical, 

 simple, ovate, elongate, obtuse, obscurely crenate, very persistent 

 and becoming large, ovate, acuminate, obtuse, cuneate at the base, 

 but compressed there and appearing cordate where it suddenly 

 widens, lobulate, ultimately oblong, coarsely dentate, alternately 

 penninerved, the nerves not entering the lobes directly, but uniting 

 with a strong branch of the nerve immediately above, and forming 

 a span which is less than a right angle, reticulate, rugose, fleshy, 

 densely covered with short fleshy adpressed pale grey hairs with a 

 few reddish ones intermixed, cinereous above, rufous beneath from 

 the intermixture of pale and red hairs, with prominent projecting 

 nerves and prominently reticulated. 



Ultimately the leaf is oblong, obtuse, slightly narrowed upwards, 

 tapering at the base and appearing cordate by the contiguous sides, 

 doubly dentate or lobular-dentate with gland-tipped teeth, alter- 

 nately incurvi-penninerved, strongly rugose and reticulate, glandular- 

 pubescent on both surfaces, cinereous above, rufous or reddish 

 beneath, twelve to thirty-six inches long and nine to twenty inches 

 at the broadest.

FrvAt and Seed. The ovary is superior, two-celled, with 

 two parallel, distant or contiguous, but distinct placentas, 

 adnate to the septum, but sometimes though rarely one-celled 

 with two parietal bifid placentas. The ovules are numerous, 

 horizontal, anatropous, and arranged in a single series or 

 rather irregularly in one to many series. The fruit is capsular, 

 dehiscing along the middle of the carpels or breaking away 

 from the septa ; or it is fleshy, indehiscent and more or less 

 filled with fibrous, spongy or pulpy placentas. The seed
