60. CERCIS, RED-BUD, JUDAS-TREE. (Ancient name of the ori- 

 ental species : the Itlnglish name from the old notion that this was the tree 

 whereon Judas hanged himself) 



C. Canadensis, American Red-bud. Wild from New York S. (but 

 probably not in Canada as the name implies) : a small, handsome tree, orna- 

 mental in spring, when the naked branches are covered with the small but verj 

 numerous tiowcrs, of the color of peach-blossoms or redder ; the rounded leaves 

 are somewhat pointed, and the pods scarcely stalked in the calyx. 



C. Siliquastrum, European R. or Judas-Tree. Barely hardy N., 

 except as a shrub ; has larger flowers, pod raised out of the calyx on a short 

 stalk, and almost kidney-shaped leaves. A seeming variety of this inhabits 

 Texas and California.

 leaves used in place of true, oriental Senna. Fl. summer, in all ours yellow. 



§ 1. Smooth herbs, in rich or alluvial soil, with rather large leaflets, deciduous 

 stipules, floioers in short axillary racemes or crowded in a panicle, and the 

 10 stamens unequal, some of the upper anthers imperfect. 



C. Marilandica, Wild Senna. The only common sort at the north, 

 3° -4° high, with 6-9 pairs of narrow-oblong blunt and mucronate leaflets, 

 a club-shaped gland on the common petiole near the base, bright yellow petals 

 often turning whitish when old, blackish anthers, and linear flat (at first hairy) 

 pods. 2/ 



C. oecidentMis, Western S. or Styptic- Weed. Common S., nat 

 from South America: l°-5° high, with 4-6 pairs of lance-ovate acute leaf-

 5' long. (T) 



C. obtusifdlia. From Illinois and Virginia S. ; with 2 or 3 pairs of ob- 

 ovate leaflets, a pointed gland between the lowest, the pale flowers in pairs, and 

 slender curved pods 6' - 10' long. ® 



§ 2. Loio and spreading, smooth or roughish hairy herbs, in sandy or dry barren 

 soil, with persistent striate stipules, and 10 — 20 pai}'s oj" small linear-oblong 

 oblique or unequal-sided leaflets, which are someivhat sensitive, closing when, 

 roughly brushed ; a cup-shaped gland below the lowest pair : flowers clus- 

 tered in the axils. 

 C. Chamsecrista, Large-fl. Sensitive or Partridge Pea. Flowers 

 pretty large, showy, on slender pedicels, with the petals often purple-spotted at 

 base, a slender style, and 10 unequal stamens, some of the anthers usually yel-

 showy flowers, the short-clawed broad and jagged-edged petals 1' long and red- 

 dish-orange, and the crimson filaments 3' long. 



63. GYMNOCLADUS, KENTUCKY COFFEE-TREE. (Name from 

 Greek words for naked branch, the branches being very stout, and when the 

 leaves have fallen appearing destitute of spray.) 



G. Canadensis. The only species, a fine ornamental and timl>er tree, wild 



from W. New York S. and especially W., with rough bark, twice-pinnate leaves
