hybrid, but quite glabrous and without lobes. Ivy Hill Cemetery, 

 Philadelphia (June, 1905, Mr. Stone sent living plants now in garden). 

 Sept. 6, 1905, Stone & Brainerd; along railway near Lester Sta., 

 Tinicum, Pa., Sept. 6, 1905, Stone & Brainerd; near New Brunswick, 

 N. J., Sept. 7, 1905, whh both parents, Brainerd; Curtis Street, South- 

 ington. Conn., May 28, 1899, C. II. Bissell, named by Mr. Pollard, 

 "F. sagittata, rank development"; roadside, East Lyme, Conn., Aug. 

 29, 1905, Miss A. M. Ryan. — The rank cespitose growth of the hybrid 

 is shown by the fact that eleven ample specimens were made from one 

 of the New Brunswick plants. In four capsules of the Ivy Hill plant 

 the number of seeds averaged 29; the plants from the other stations 

 are less fertile. The capsules of the Ivy Hill plants are nearly green 

 in color, those of New Brunswick brown-spotted; but the capsules of 

 V. papilionacea at these two stations differ in like manner. 



22. V. AFFiNis X SAGITTATA. — Leaves narrowly deltoid, the 

 upper half minutely and distantly serrate, the basal lobes rounded 

 and coarsely toothed, forming a broad sinus; cleistogamous flowers 

 and fruit intermediate. From two stations: Patuxent, Md., June 4, 

 1905, //. D. House, no. 972; Tinicum, Pa., Sept. 6, 1905, Stone & 

 Brainerd. — With the Patuxent specimen was mixed a plant of I '. 

 ajfinis, the form with minutely pubescent capsules; it was interesting 

 to see that the capsule of the hybrid had also this mark, which is not 

 found in any other species of our blue stemless violets. The Tinicum 

 plant was discovered at Mr. Stone's station for V. rrenulata, Greene, 

 a phase of V. affinis found in open bogs; and F. sagittata grew at no 

 great distance. 



23. V. PALMATA X SEPTE.MLOBA. — Differs from I', septemloba in 

 the direction of F. palmata, in its large less divided leaves with broad 

 middle lobe, in pedicels one half as long, in bearing pubescence on 

 petiole and veins of leaf, and in having summer capsule dotted with 

 brown; differs from F. palmata in the direction of ]\ septemloba, in 

 being less pubescent, in producing slim long-auricled cleistogamous 

 flowers on ascending pedicels, in having nearly green cleistogamous 

 capsules. — Discovered at Milltown, N. J., by Mr. House in June, 

 1904. A live plant sent at that time has attained to a large size in the 

 garden. About one fifth of the ovules mature into seeds; the leaves 

 in late summer become ranker and less divided. — In March, 1904, I 

 noticed in the National ^Museum two sheets of what seemed to be this 

 hvbrid from Stratford, Conn., ISIav 24, 1893, E. II. Eames. The
