Planta quam typica multo robustior, foliis carnosulis, ciliatis, 

 late obovatis seu late oblanceolatis, basin versus cuneato-attenu- 

 atis, apice plerumque trilobatis nee omnibus integris. Scapus 

 5-13 cm. altus, inflorescentia ad 8-flora.

 {K. Jimbo I 1891). 



Obs. The present variety resembles var. Idzouroei, which 

 comes between the typical form and this new variety ; it is, how- 

 ever, smaller in habit, 1-3-florous as in the type. The leaves in 

 the typical form are entire, in var. Idzouroei usually trilobate, and 

 often mixing entire ones.

Obs. Prof. Miyabe followed A. Gray {of. Proc. Am. Acad. xx. 

 p. 11) in uniting S. Tilingiana Eegel to the present species. The 

 close resemblance as well as the similar geographical distribution 

 of both the species render the supposition not unreasonable. So 

 far as I can decide from Eegel's original specimen collected by 

 Tiling, I agree with Engler in separating S. Tilingiana from 

 S. rejiexa. The two species are very similar in appearance, but 

 S. Tilingiana has nearly entire or little repand leaves and capsules 

 not split more than half-way down. Franchet considered our 

 plant to be a variety of S. virginiensis Michx., which, though it 

 has a close relation to our plant, is, as A. Gray already pointed 

 out, quite a different species. Boissieu followed Franchet's
