998. D. systilioides, Ren. & Card., Botanical Gazette, Vol. 

 XXX., p. 16. 



A full description in Latin is given besides the following which 

 is sufficient for our purpose. 



By the lid attached to the columella and persistent after the 

 opening of the capsule, this species resembles D. Systilius^ Schimp., 

 but is clearly distinct from it by the leaves of a more obscure 

 and more papillose areolation, with a distinct pellucid yellowish 

 border, the nerve stouter, brownish, not or very shortly excurrent, 

 and by the total lack of peristome; at least none of the capsules 

 we have been able to examine show the slightest trace o. this 

 organ. The pellucid border of the leaves shows some relation- 

 ship between D. systilioides^ Ren. & Card., and D. Porteri^ James, 

 but the latter has a much narrower capsule, with a highly conic 

 lid not adhering to the columella, and the peristome and annulus 

 are well developed.
