PULSE FAMILY. Ill* 



1. Gr. Canaden'sis, Lam. Leaflets 7-13 on the subdivisions, ovate, 

 petiolulate, the lowest a single pair ; flowers in axillary racemes. 



CANADIAN GYMNOCLADUS. Kentucky Coffee-tree. Kentucky Mahogany. 



Stem 50-80 feet high, branching. Leaves 2- 3 feet long, bipinnately branching ; leaf- 

 lets rather alternate, entire, about 3 inches in length. Flowers greenish white. Legumes 

 6-10 inches long, and 1-2 inches wide, somewhat falcate ; seeds nearly orbicular, a little 

 compressed, over half an inch in diameter. 



Rich woods : W. New York to Illinois and south-westward ; also in cultivation. Fl. 

 May. Fr. October. 



Obs. This fine tree has been introduced into the Eastern States, from 

 the West ; and although not equal to some others, as a shade tree, is 

 worthy of a place in all ornamental plantations. The timber is valuable, 

 possessing a fine and close grain ; qualities which adapt it to the use of 

 the cabinet-maker. 



19. GLEDIT'SCHIA, L. HONEY LOCUST. 



[Named in honor of John Gottlieb Gleditsch, a German Botanist.] 



Flowers polygamous. Sepals 3-5, equal, united at base. Petals as 

 many as the sepals, or fewer by abortion or by the union of the two 

 lower ones. Stamens as many as the sepals and opposite them, or by 

 abortion fewer. Legume stipitate, often intercepted internally between 

 the seeds, dry or with sweet pulp around the seeds. Seeds oval. Trees : 

 the super-axillary branchlets often converted into simple or branched 

 spines. Leaves even-pinnate or bipinnate (often both forms on the same 

 tree.) Flowers small, somewhat spicate. 



1. G, triacan'thos, L. Spines stout, mostly triple ; leaflets linear or 

 lance-oblong, somewhat serrate ; legumes oblong, much compressed, 

 somewhat falcate and undulate, many-seeded, the intervals filled with 

 sweet pulp. 



THREE-THORNED GLEDITSCHIA. Honey-locust. Three-thorned Acacia. 

 Fr. Le Fevier a trois Epines. Germ. Der Honigdorn. 



Stem 30-50 or 60 feet high, and 2-3 or 4 feet in diameter. Leaflets about an inch or an 

 inch and a half long. Flowers yellowish green. Legumes 6-12 or 15 inches long, and an 

 inch or more in width, thin and wavy, or somewhat twisted. 



Pennsylvania to Louisiana : often cultivated. Fl. July. Fr. September -October. 



Obs. The light foliage of this tree gives it a pleasing aspect, but it is 

 not a good shade tree. It is in frequent cultivation as an ornamental 

 tree, and seems to be nearly naturalized around New- York. It has been 

 used with success in some localities for hedging, its formidable thorns 

 compensating, by their utility, for the beauty which a hedge with such 

 light foliage must lack. The thorns are knocked off by the winds and, 

 being often so compound that however they may lie, some points will 

 stick up, prove very troublesome by wounding the feet of cattle.
