' Tlio other siwciraoua of tliia form of S. perfoVafa in tlm Naiion.al ITcrbariinu aro: No. G79, of M.'x- 

 lean Boundary Survey; De. Palmer's No. IGg, from Indian Territory; and a plant coUocted by C 

 Thomas in tho Rocky Mountanis, in 1809. Tho Mexican Ponn.lary i.huit w.a.s first named Dvsmieodon 

 ovatum Nutt., but was sub.seaucutly clianged to Specularia bijlora Gray, with a question mark. TIio 

 other two plants were both found v itli Specularia perfoliata. 



Tho capsules of this form are about J longer than in (ho cmnmon form ; tho seeds, on (he other hand, 

 are i smaller, and more oval, tho ratio of the two diameters bcins as 3 to 2. Spreularla leptocarpa h.as 

 seeds of about this shape, but just double this length. Tlio e.'eds of SpecuUna hijlora tho Syu. V\. 

 11, 11, describes as lenti. ular, but on oxaiuiuing some ripo seeds of Keverchon's Texan plant under this 

 name, I find it to bo oval, and of about the same size as in the plant.s under consideration. Tlie cliar- 

 nctoristic diftcrenco between .S:ppo!ffrtfiaijc):/-o;;af(i and 6i/Ior(i is in the leaves, which are bro.aderand 

 more amplexicaulo in S.jfjo/oJ.afa, narrower and more distant on tlio stem in S. &i/ora, but still am- 

 ploxicanlo; the length of tho capsule varies some in both, so does tiie position of the valves, certainly 

 in perfoliata: the Syn. Fl. ii. 11, places those " at or below tho middle," but both tho liguro in IIIJK.

 niiddlo. Tho plants under considcrati.m Iiave the valves of tho capsules above tho middle, but have 

 tho leaves of «. p«r/oiiaia. On the other h.and. Mr. F. V. Coville colloctod a plant in Pennsylvania 

 which ha..^ (he more slender aspect, in leaves .and stem, of S. biriora. Tliero is other material in t lie 

 National II. m barium tending to show tliat Specularia perfoliata and hijlora arc only variatiims of oiw 

 good species, variable in width of lo.af, length of capsule, and position of valv.iiur openings on the 



same.
