The Flora of the Cayuga Lake Basin 279 



Dry open woods just s. of Esty Glen (A. J. E. & L. II. MacDaniels) ; one-half mile 

 n. of Esty Glen; Farley Point (£>.) ; Utt Point. 



S. N. H. to Minn., southw. to Fla., La., and e. Kans. ; rare on the Coastal Plain. 



3. L. intermedia (Wats.) Britton. (See Rhodora 26:29. 1924. L. frntescens of 



Gray's Man., ed. 7. L. violacea, form, no. 211 of Cayuga Fl.) 



Dry sandy or gravelly open woods, in noncalcareous soils ; frequent. Aug.-Sept. 



On the hills w., s., and s. e. of Ithaca in woods with ericaceous plants and chest- 

 nut, on the ravine crests and cliffs along Cayuga Lake, and in the sandy soils n. 

 of the lake; rare or absent in the McLean region and on the clays and richer soils 

 back from the lake shores. 



S. Me. to Minn., southw. to Fla., 111., and Tex. ; common on the Coastal Plain. 



Forms occur [hillside near White Church (D.) ; bank of ravine n. of Enfield 

 Glen (D. !) ; Cascadilla woods (D.\) ; Junius] which agree more or less closely 

 with L. Nuttallii Dark (L. violacea, form, no. 213 of Cayuga Fl.) and with L. 

 Stuvei Nutt. (form, no. 214 of Cayuga Fl.). These specimens do not constitute 

 distinct categories, but present various combinations of the characters of L. inter- 

 media and L. hirta. In one instance the Stuvei and Nuttallii types were growing 

 together and were accompanied by both the species mentioned above. In this region, 

 therefore, the so-called L. Nuttallii and L. Stuvei are to be considered hybrids of 

 L. intermedia and L. hirta. Along the coast, however, the real L. Stuvei is appar- 

 ently a different plant and a distinct species. 



4. L. hirta (L.) Hornem. Bush Clover. 



Dry gravelly or sandy open woods and banks, in noncalcareous, usually acid, soils ; 

 common. Aug.-Sept. 



Distribution similar to that of the preceding species. 



S. Me. to Minn., southw. to Fla., La., Ark., and Tex. ; common on the Coastal 

 Plain. 



5. L. capitata Michx. 



Dry sandy or gravelly banks, in acid soils ; rare. Aug. 20-Sept. 20. 

 "Wild bank beyond the Fleming S. H." (D.\), that is, behind the Valley Ceme- 

 tery, s. w. of Ithaca. 

 Me. to Minn, and Kans. southw. to Fla. and La. ; common on the Coastal Plain. 



16. Vicia (Tourn.) L. 

 a. Flowers sessile, axillary, in groups of 1-3. 

 b. Leaflets of the upper leaves gradually acute. 1. V. angustifolia 



b. Leaflets of the upper leaves truncate or refuse, mucronate. 



la. V . angustifolia, 



var. segetalis 

 a. Flowers racemose or spicate, secund, on well-developed peduncles. 

 b. Flowers 2-4 mm. long; seeds 4 (rarely 3-6) ; racemes 1-6-flowered. 



2. V. tetrasperma 

 b. Flowers 6-18 mm. long; seeds 6 or more; racemes 2^40-flowered. 

 c. Plant appressed-pubescent or glabrous. 

 d. Flowers 8-40, each 6-12 mm. long ; leaflets inconspicuously veined, strigose. 

 e. Calyx lobes very unequal, the lower ones subulate, the upper ones 

 almost obsolete; racemes dense, the flowers 15-40, deep blue or purple; 

 leaflets linear or elliptic-linear, mucronate; stipules usually with a 

 strong lobe above the base, otherwise entire. 3. V. Cracca 



e. Calyx lobes nearly equal, short-triangular ; racemes loose, the flowers 

 8-20, pale ; leaflets elliptical, scarcely mucronate ; stipules entire, or 

 with a small tooth-like lobe at the base. 4. V. caroliniana
