392 LEGUMIlNUriiE. Hoffmanseggia. 



stipules. Flowers deep rose-color, appearing before the leaves : pedicels 

 fascicled along the branches, 4-8 together. 



Tho legume of Cercis is wholly similar to that of Calpurnia and Bowdichia, 

 and its aflinity with Cladrastis is evident. 



1. C. Canadensis (Linn.) : leaves broadly ovate-cordate, acuminate, hairy 

 along the veins beneath. — Linn. ! spec. 1. p. 374 ; Michx. ! Jl. 1. p. 265 ;

Banks of rivers, &c. from (Canada, according to Pursh) New Jersey ! 

 Pennsylvania ! and Ohio ! to Louisiana ! and Florida ! March-April. — Tree 

 15-30 feet high, vdth somewhat geniculate branches. Flowers small, pur- 

 plish, acid to the taste : pedicels filiform. — Red-bud. Judas-tree. 



Tribe IX. CASSIE^E. Bronn ; DC. (excl. gen.) 



Corolla regular or mostly irregular, not papilionaceous. Stamens 

 10, or sometimes fewer, distinct: anthers sometimes of 3 forms. 

 Legume continuous (not jointed), l-celled, often intercepted between 

 the seeds, dehiscent. Seeds frequently with a small quantity of 

 albumen. Embryo straight.— Trees, shrubs, or herbs. Leaves 

 (usually abruptly) pinnate or bipinnate, not stipellate. 



54. HOFFMANSEGGIA. 



HofFmanseggia & Pomaria, Cav. ic. ; DC. — Melanosticta, DC. ? 



Sepals 5, united into a short obconic base, somewhat equal. Petals 5, 

 obovate, on short claws, somewhat unequal, spreading, the upper one con- 

 cave, one or more of them often glandular at the base. Stamens 10 : fila- 

 ments mostly hairy or glandular, and thickened or dilated towards the base, 

 nearly equal : anthers oval, nearly unifonn. Style as long as the stamens, 

 somewhat thickened toward the apex. Legume oblong or linear, often fal- 

 cate, compressed, dry, 2-valved, 2-seeded. — Low perennial herbs or sufFru- 

 tescent plants, often dotted with black glands. Leaves abnqitly or unequally 

 bipinnate. Kacemes opposite the leaves : flowers yellow. Glands either 

 sessile or pedicellate. 



We unite Pomaria and HofFmanseggia of Cavanilles without hesitation. There 

 appears to be no essential difference in the flowers, and both have the pinnae of 

 the leaves either equal in number or with a terminal one, the racemes opposite the 

 leaves, &c. Our H. Drummondii differs from HofFmanseggia proper, chiefly in 

 the broader and shorter pods, and in wanting the glandular tufl at the base of the 

 4 lower pet;ils ; and from Pomaria in the straight filaments, the little tuft at the 

 base of the larger upper petal, and the pedicellate glands. The plant which in 

 the account of Dr. James's Collection v/as referred to Pomaria glandulosa, Cav. 

 (HofFmanseggia glandulosa, T. ^- Gr.) is certainly a difFerent, though nearly allied 

 t^pecios; the stipules being entire, and the leaves not abruptly pinnate (as inadyer- 

 tcntly described), the legume more lunate, &c. There is nothing in the character 

 of Melanosticta, DC, to distinguish it from the present genus.
