2 — 3. Probably sucb leaves develop only in old plants. In quite young |)lants 

 the pinnæ are sometimes quite entire, ovate or nearly circular, the veins free: such 

 forms have been referred to D. cordata. — Some forms are nearly destitute of 

 stellate hairs. 



The following specimens are typical, if such a term may be used here.

3. var. angusta n. var. 



P'ronds rather uniform, often radicant, very short-stalked, linear, often con- 

 siderably narrowed downwards. Pinnæ distant, small, rarely more than IVacm 

 long, often only Vs cm, scarcely '/- en broad, obtusely rounded at the apex, the 

 margins entire or slightly crenated, rounded or auricied at base; secondary veins 

 once or twice forked, free or united near the edges. 



Very characteristic by the long, very narrow, flaccid leaves, which are often 

 rooting as in eiireptans. It approaches D. cordata, from which it differs by its di- 

 ,stant pinnæ, thinner texture, long proliferous apex and pubescence.

4. var. conformis n. var. 



Differs from var. eureptans by its mostly uniform leaves, which have the ge- 

 neral habit of the short-stalked mostly sterile leaves of eareptans, but the stipites 

 .are rather long and the lamina often much larger. Long-stalked, difl'erently shaped 

 leaves are not to be found, but often the radicant leaves are somewhat narrower 

 than the non-radicant ones. — All leaves long-stalked, stipe often as long as the 

 lamina or even longer. Lamina mostly lanceolate in outline, often 20 cm or more 

 long but as a rule shorter, 5 — 8 cm broad, shortly narrowed downwards. Pinnæ 

 very short-stalked the lower ones mostly rather shortened, distant, the largest up 

 to 5 cm long, often cut V;i or more to the costa and cordate at base. — It is less 

 proliferous than eiireptans, still one or two radicant leaves are to be found in most
