54 Rhodora [March 



"Crevices of rocks in open woods with parent forms," Granny Hill, 

 Lexington, Mass., Sept. 20, 1903, Robinson ii- Gnrumnu. Dr. Rob- 

 inson first recognized and called my attention to this hybrid; last 

 spring Dr. Greenman kindly i)rocured for me about twenty living 

 jjlants; I visited the station in August. The leaves vary consider- 

 ably in relative width and in lobation, as do those of V. palmafa; 

 and those produced in late summer and autumn are often uncut or 

 slightly lobed, as though anticijiating the earliest vernal leaves. 

 Additional stations are: "pastures," Portsmouth, X. H., July 15, 

 1894, Charles A. Daris; "moist woods imder pines," Kensington, 

 N. H., July 2, 1<S99, .1. .1. Eaton; Niles Place, Ledyard, Conn., June 

 24, 1900, Mrs. C. B. Craves; East Lyme, Conn., 1904 k 1905, several 

 colonies, Mws A. M. Ryan. (See pi. 70.) 



19. V. FIMRRIATIM.A X PAPILIONACEA. — {V . papiHonacca ahrrrans 

 Stone, 1. c, p. 683, pi. xxxvii, fig. 4-6). This is hardly distinguishable 

 from hybrid no. 3 (Uhodora, vi. 215). I', sororia is separated from 

 V. papilionacea chiefly by pubescence; but both hybrids inherit pubes- 

 cence from V. fimhriatvla, and the other parent must be determined 

 chiefly from its presence with the hybrid. No. 19 seems to occur fre- 

 quently along the Atlantic border. 



20. V. I'Ai.MATA X SAGITTATA. — Differs from T. sagiiiaia in having 

 wider pubescent leaves, more or less lobed near the middle, in having 

 cleistogamous flowers with appressed eiliate auricles, and in having a 

 brown-spotted summer capsule on much shorter peduncles. It differs 

 from V. palmata, var. dilatata in having ovate-oblong leaves with 

 coarsely toothed or incised basal lobes, and in having long slender 

 cleistogamous flowers on ascending peduncles. In each case the 

 departure is in the direction of qualities jiossessed by the other parent. 

 The autumn leaves are cordate and uncut; capsules few-seeded — 

 nineteen in the four cajisules examined; both parent species near by. 

 — This hybrid was collected by Mr. House in May and June, 1904, 

 near New Brunswick, N. J., nos. 39, 53, 6S. 1 have had a specimen 

 in the garden since June 15, 1904, and have twice visited the station. 

 I place here also two specimens in the Gray Herbarium: Centreville, 

 Del.. May 19, 1877 and Oct. 27, 1878,^. Covivions; near Garrison's, 

 N. Y., May, 1886, Ed. S. Denton. The last has a more deeply cut 

 leaf than the two others, as though from typical V. palmata; Dr. Gray 

 has written on the sheet "V. palmata, Iv toward sagittata." 



21. V. PAPILIONACEA X SAGITTATA. — Not uulikc the last described
