brids, and produced numerous cleistogamous flowers, most of which, 

 however, were quite sterile, turning yellow after a few weeks; in those 

 that produced seeds the average number was 4|. The intermediate 

 character of the foliage is shown in plate 67 (fig. a) from a plant in 

 cultivation September 13. The leaves of the parent species (figures 

 b & c) are from herbarium specimens of plants growing with the hy- 

 brid and collected by Miss Mulford. Mixed with the live plants sent 

 by her in September, 1904, were also five plants of V. scptemloha and 

 one of V. fimbriatula, showing that the three forms grew in close prox- 

 imity to each other. 



14. V. cucui.LATA X SAGITTATA. — I would SO dispose of the col- 

 ony of plants discovered by Mr. Witmer Stone, and described as V. 

 emarqinain (Tinicum, Pa., April 25 & June 21, 1903, Proc. Acad. 

 Phila., 1903, p. 685). Last August I visited with him this station; 

 the particular colony seen two years before had disappeared in a dense 

 growth of briars and sprouts, after a recent chopping; but about 200 

 meters away a plant was found quite like those formerly collected, 

 growing with what I regard as the parent species. These plants dif- 

 fer from the ordinary V. emarginata in having blue, not violet, petals 

 (Mr. Stone says "between campanula blue and mauve of Ridgway"), 

 in having on the spurred petal "scattered hairs" rather than a dense 

 beard, and in having leaves with sharper coarser teeth at the base. 

 The last character suggests V. mgittata; the two others, V. cucuUata. 

 The cleistogamous flowers in the August plant are also decidedly like 

 those of the latter species, and the contour of the leaf is a fair com- 

 promise. The specimens of both collections show impaired fertility. 



15. V. CUCULLATA X SEPTEMLOHA. — (F. BriUoniana X cucid- 

 lata, House, Torr. Bull, xxxii. 255, pi. 17. V. notabilis, Bicknell, 

 Torreya, iv. 131). I have had a specimen from ?vIilltown, N. J., 

 growing in the garden since June, 1904, and visited the station in 

 August of that year. Mr. BickneU's exact description and Mr. 

 House's excellent drawing leave but little to be added. Mr. Stone 

 also (1. c, p. 680) collected it at Spririgdale, N. J. in 1903, and sur- 

 mised it then to be the hybrid here indicated. I place here also speci- 

 mens of Mr. E. S. Steele, Berwyn, Md., May 15, 1902; and of Prof. 

 Greene, Stony Run, Md., ApriJ 30, 1898. 



16. V. CUCULLATA X (?) ENL\RGiNATA. — This is probably the 

 disposition to be made of Mr. BickneU's V. lavandulacea (Torreya, 

 iv. 130). The beautiful specimens sent me were collected at three
