THE NATIVE AND CULTIVATED VICIEiE AND 

 PHASEOLE^ OF OHIO. 



Gertrude Bartlett. 



In the following study of the native, introduced and cul- 

 tivated Vicieae and Phaseole^ of Ohio, an attempt has been made 

 to find the most evident differences so that the species may be the 

 most easily determined, and also to give a phyletic arrangement 

 in so far as this is possible in plants so closely related. 



The species of the Ohio State Herbarium were studied for 

 characters and distribution, and most of the cultivated species 

 were grown in the greenhouse, in order that definite data might 

 be obtained, both of the vegetative parts and flowers. The 

 actual measurements were taken from herbarium specimens and 

 from the living plants and compared with those of Britton's 

 Manual. The keys are based upon leaf, stem and flower char- 

 acteristics present at the time of flowering. The habitat is 

 usually given, also the distribution by Counties as represented 

 in the Ohio State Herbarium. Economic notes and other miscel- 

 laneous facts are added, because of the great importance of these 

 plants in agriculture and household economy. 



FABAT^, VICIE^ AND PHASEOLE^, 



Erect or trailing herbs, or climbing vines either twining or 

 with tendrils, ours always herbaceous. 



Leaves compound, pinnate or trifoliate, rarely reduced to 

 one leaflet, alternate with stipules frequently having nectar 

 glands. Leaves often ending in a simple or branched tendril, 

 or in a short point. Roots with large or small tubercles. Flowers 

 bisporangiate, hypogynous, pentacyclic pentamerous except the 

 gynecium, zygomorphic, the two outer lower petals, more or less 

 united forming a structure called the keel, which encloses the 

 stamen column. Calyx of five united sepals, its lobes sometimes 

 obscured. Stamens diadelphous, sometimes monadelphous. Car- 

 pel one with two lateral sutures, one of which is the placenta. 

 Ovules one to many. Fruit a legume, dehiscent by two valves, 

 often twisting spirally or indehiscent. Seeds with little or no 

 endospemi. Cotyledons large and thick. 



KEY TO THE TRIBES. 



1. Leaves evenly pinnate with tendrils or bristles, or if 

 odd-pinnate, then the stem 4-angled or with leaflets 9-25 and 

 deeply serrate. Vicieae. 



1. Leaves odd-pinnate without tendrils, the leaflets not 

 serrate and the stem round, or roundish, frequently twining. 

 Phaseolese.
