racemes, associate this plant closely with Hnittixiu l<tn<-e<>tt<i" . A very 

 superficial examination of the characters involved would have convinced 

 Mr. Holzinger that he was in error, even if he had chosen to regard the 

 principles of geographic distribution as of no consequence. Hirptixin 

 [<iii<-tol<itii is a plant of the southeastern Atlantic coast from South Car 

 olina to Florida, and is not known from the Gulf states. Its leaves are 

 by no means sessile, but distinctly petiolate, the petioles in many cases 

 a centimeter or more in length, while the leaflets, instead of being short 

 and obovote as in H. Te.mna, are elongated, and unmistakably lanceolate 

 in outline. The stems, moreover are glabrous in lanceolata. The near 

 est ally of B. Texana is probably B. laevicauUx, a species which is glab 

 rous throughout, however, even to the pod. Excellent fruiting speci 

 mens were obtained by Mr. Ball near Alexandria, La., June :j, 189!) (No. 

 546), growing on hillsides under scrub oaks. 



Stylosanthes biflora hispidissima (Michx), n. comb. 



Styloscmihes hisjnda var. b. hispidissima Michx., Fl. Bor. Am. 1:75 

 1803. 



This form differs from the type in the long hirsute pubescence with 

 which the stem and often the foliage is clothed. Michaux's character 

 ization of the variety as "universe hispidissima" leaves little doubt as 

 to its identity. The plant is more prostrate in habit and diffusely 

 branched than the ordinary form of *S'. biflora. Mr. Ball's specimens 

 were collected at Alexandria, La., June 10, 1899 (No. 621). 



Prunella vulgaris scaberrima n. var. 



Stems purple; herbage and inflorescence densely hispid and scabrous- 

 pubescent with white hairs; otherwise similar to P. rulyari*. 



Type in U. S. National Herbarium, collected by Mr. Ball at Alexan 

 dria, La., June 9, 1899 (No. 607). The plant is there common in dry 

 soil. 



Physalis rigida n. sp. 



Perennial, from a thick root; stems tufted, erect, rigid, sulcate, more 

 or less branching, 3-3| dm. high, hispid-pubescent with flat hairs, par 

 ticularly above; leaves firm, ovate-lanceolate, obscurely repand-dentate, 

 acute at apex, tapering to base, densely pubescent when young, scabrous 

 above when mature, 4-6 cm. wide; petioles slender, 1^-4 cm long: flowers 

 small, 1-1| cm. broad, on slender hispid-pubescent pedicels; flowering 

 calyx densely pubescent, its lobes ovate-triangular, acute; limb of corolla 

 yellow, the throat dark purple; fruiting calyx nearly smooth, ovoid, ob 

 scurely 10-ribbed, 2|-3 cm. long, truncate or somewhat depressed at base; 

 pedicel refiexed, hispid-pubescent, about 2 cm. long.
