notched, abruptly narrowed into the claw ; wings and keel petals 



with blades 2 mm. long. 



In sand, Nueces Bay, Texas. 



Related to Baptism bracteata but with glabrous foliage. The 

 broad cuneate leaflets are not known in the related species. The 

 pedicels are much longer and the calyx-segments abruptly pointed

and not acuminate as they are in B. bracteata. The ovary, too, is 

 glabrous or nearly so. 



The type was collected by Mr. Heller along Nueces Bay, 

 Texas, on April 3, 1894. Number 1523. 



V POLYGALA LeWTOXII. 



Birennial. Foliage glabrous, bright green. Stem much 

 branched at the base ; branches numerous, ascending or decum- 

 bent, 1-2 dm. long, simple, sharply-angled : leaves clustered, 

 crowded, fleshy, spatulate or linear-spatulate, 1-2 cm. long, acute 

 or acutish, wrinkled in drying : racemes 1-5 cm. long, loosely- 

 flowered : pedicels slender, 1-2 mm. long : sepals various, dorsal 

 broadly oblong, anterior narrowly-oblong, both 2 mm. long, obtuse ; 



wings deep pink, inequilateral, half-rhombic, 4.5-5.5 mm. long: 

 corolla deep pink : petals about 4 mm. long, the keel more finely 

 lacerate than in P. polygama : style from the truncate top of ovary, 

 ascending, cucullate above the middle, tufted appendage and stig- 

 matic gland not approximate : capsule oblong-prismatic, 5 mm. 

 l° n g> glabrous : cleistogamous racemes slender, few-flowered ; 

 pedicels slender, 1 — 1 . 5 cm. long, curved. 



In sand, peninsular Florida. 



A unique species of a low habit, related to Polygala polygama. 

 It may be distinguished by its small, fleshy, clustered leaves. Ail 

 the parts of the flower are diagnostic, the oblong outer sepals and 

 the half-rhombic inner sepals are very different from the correspond- 

 ing organs in P. polygama. In P. Lewtonii we find a narrowly 

 oblong pod about thrice as long as broad, while in its relative we 

 have a broad pod whose length only slightly exceeds the breadth. 

 Cleistogamous flowers do not seem to be produced as freely as in 

 the case of P. polygama, and the pedicels varying from 1-1.5 cm. 

 in length have nothing similar in the latter species. 



'Triadenum longifolia. 



Perennial. Foliage deep green, glabrous: stems erect, 3-6 

 dm. tall, simple below the inflorescence : leaves opposite ; blade-
