ferns. I have specimens from Santo Domingo (Weinland, 33), 

 Cuba (Wright, 799) and Porto Rico (Garber, 41). 



Mr, Davenport informs me that Mr. Curtiss has collected a large 

 stock of this fern, and will distribute it in his fascicles for 1882, 

 which will probably contain also Asple?iiu7n serratum^ Taenitis lance- 

 data and the royal palm, Oreodoxa regia, 



■ 37. Pellaea densa. Hooker. — The range of this fern is greatly 

 extended by Prof. 0. D, Allen and his son, Mr. J. A. Allen, who 

 found it on Mount Albert, in Low^er Canada, July 30, 1881. It grew 

 exposed to the sun on the steep walls of ravines at 2,000 to 3,000 

 feet elevation. Mt, Albert is near West Longitude 69^ 30', N. Lat, 

 47^ 15'. The same plant is No. 819 of Mr. Cusick's Oregon distri- 

 bution. 



38. Phegopteris calcarea. Fee. — A second station for this very rare 

 plant is at Decorali, Winneshiek Co., Iowa, where it was found last 

 season **in the crevices of the north side of a limestone bluff" by 

 Mr. E. W. Holway. My specimens were kindly sent by Mr. J, C 

 Arthur, of Charles City, Iowa. 



39. Aspidium aculeatum^ var. scopiilinum^ Eaton. — This has been 

 reported in the Bulletin from Utah, by Mr. M. E. Jones. The 

 Messrs. Allen collected it July 26, 1881, on the side of a rocky ravine 

 on Mount Albert, Lower Canada. Mr. Suksdorf sends it also from 

 Mt. Adams, Washington Territory. Some of Mr. Lemmon's plants 

 seem to show so gradual a transition of this into A, mohrioideSy that 

 it would look as if the latter would have to be considered an extreme 

 form oiA, aculeatum, 



40. Aspidium irifoliatum^ Swz, — Mr. Curtiss has now distrib- 

 uted fine specimens of this tropical fern. Mr. Davenport has re- 

 ceived from Dr. Engelmann a specimen collected long ago in West- 

 ern Texas by Lindheimer. That region of Western Texas has 

 scarcely been visited by botanists for many years, and not a few of 

 our rarest ferns are found principally there, 



41. Woodsia obtusa^ var. glandulosa, is the name suggested by 

 both Mr. C. E. Faxon and myself for the form called W, Pluminerae 

 by Mr, Lemmon, The involucre is exactly that of W, ohtusa^ the 

 habit scarcely differs, and the glandular pubescence is so variable, 

 often almost lacking, that no reliance can be placed upon it for a 

 specific distinction. This fern has been badly mixed by collectors 



with W. Mexicana, The affinity of the latter is rather with W. 

 scopulina, 



^ 42. Ophioglossum vulgatum, L. — Falcon Valley, Washington Ter- 

 ritory, Suksdorf, 1881. Mr. Davenport kindly sends me this, and 

 with it very immature plants of what is probably the same thing from 

 near San Diego, just collected by Dr. Parry, 



Torenia Asiatica is a pretty little hot-house plant of trailing 

 habit, which will thrive excellently well out-of-doors during the 

 summer. It has a prismatic calyx, two-lipped, and with sharp angles. 

 The corolla is '* short, funnel-form or tubular, with an inflated throat, 

 4-lobed, the upper lobe (sometimes slightly notched) outermost in 

 the bud." The extreme portion of all but the upper lobe is of a deep
