THE NATIVE AND CULTIVATED VICIEAE AND 
PHASEOLEiE OF OHIO. 
Gertrude Bartlett. 
In the following study of the native, introduced and cul¬ 
tivated Vicieae and Phaseoleas 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. 
FABATiE, VICIEiE AND PHASEOLE.E. 
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 
endosperm. 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.
