1. Wisteria macrostachya Nutt. (Kraunhia macrostachys (T. & G.) 

 Small of Britton and Brown, Illus. Flora, ed. 2.) Kentucky Wisteria. 

 Map 1231. I collected this species in a second growth wooded ravine May 

 19, 1918. There were several vines supported by low trees and shrubs 

 about 10 feet high. My specimen has pubescent branches and branchlets ; 

 4 leaves, 15-23 cm long, all with 9 leaflets ; leaflets slightly pubescent on 

 both sides, more or less acuminate; inflorescence 21 cm long; pedicels 

 about 10 mm long, glandular ; calyx tube glandular, about 4 mm long, the 

 longest lobes about 2 mm long ; spur of wings of corolla about as long as 

 the claw; pod glabrous.

3733. ROBINIA L. 



Branchlets, petioles, and pods glabrous; flowers white 1. R. Pseudo-Acacia. 



Branchlets and petioles bristly; pods hispid; flowers pink or purplish. (See excluded 

 species no. 394, p. 1066.) R- hispida. 



1. Robinia Pseudo- Acacia L. Black Locust. Map 1232. This species 

 has been freely planted since pioneer times and has escaped in all parts 

 of the state. It was, no doubt, a native in the southeastern part of the 

 state near the Ohio River.

la. Astragalus canadensis var. longilobus Fassett. (Rhodora 38: 94.

 I have it from Elkhart, Gibson, Kosciusko, and Warrick Counties. All

3774. CORONlLLA [Tourn.] L. 



1. Coronilla varia L. Crownvetch. Map 1234. This weedy peren- 

 nial has been reported from Boone, Grant, Lagrange, Lake, and Marion 

 Counties. A clump of this species was found in a waste place in Bluffton, 

 Wells County, and, its weedy nature being unknown, was planted in our 

 field for observation. We soon learned by its rapid spread from under- 

 ground stems that it would be a pest but kept it until it flowered in order 

 to ascertain its identity. We then destroyed it but neglected to preserve a
