8. G. Drummondii, Torr. & Gray (Schizocarya, Spach). Glabella 

 vel puberula ; bracteis caducis ; calycis segmentis tubo duplo longi- 

 oribus, fauce cum basi styli tomentosa ; appendicibus staminum petalis 

 antepositorum cseteris manifeste brevioribus ; indusio stigmatis quadri- 

 partite superne libero ; fructu glabro superne conico-pyramidato in- 

 feme in collum angustum pedicelliforme contracto. — Texas and New 

 Mexico. 



* * Fruchis 171 pedicellum manifeslum clavato-attenuatus vel contractus. 



9. G. FiLiPES, Spach (Monog. Onagr. p. 59). Puberula vel gla- 

 brata, habitu et foliis G. angustifolice ; calycis segmentis tubo elongate 

 clavato paulo longioribus ; stylo basi subglabro ; fructu parvo superne 

 ovate-pyramidato apice obtuso basi in pedicellum clavatum contracto. — 

 Virginia and Ohio to Florida and Arkansas. — This species is most 

 nearly related to G. angustifolia ; but besides its pedicellate fruit, 

 which makes it necessary to refer it to this section, the anthers are 

 oblong-linear. 



10. G. SINUATA, Nutt. Glabra ; caule superne nudo ; foliis prje- 

 sertim infimis sfepe sinuato-pinnatifidis ; calycis segmentis tubo brevi- 

 obconico 2-3-plo longioribus; stylo basi creberrime villoso; fructu 

 glabro immature fusiformi obtusangulo, costis inter angulis obsoletis. — 

 Arkansas and Texas. 



11. G. viLLOSA, Terr. Canescenti-pubescens, caule nunc villoso; 

 calycis segmentis tubo brevissime obconice quadruple longioribus ; 

 fructu glabro evato-oblongo tetraquetro inter angulos acutissimos ecos- 

 tate. — Texas and Arkansas. — Root truly perennial. 



12. G. MACROCARPA, sp. nov. Caulibus e radice perenni ramu- 

 lisque pube hirtella scabris ; foliis parvis integris margine hispidulis ; 

 calycis segmentis tubo paulo longioribus ; fructu (baud maturo) 

 canescenti-puberule fusiformi, obtusangulo costis validis inter angulos 

 percurso. — Southwestern Texas. Wright (No. 1879), Bigelow ; — 

 referred to G. villosa in PI. Wrightiange, 2. p. 59, and in Bet. Mex. 

 Bound. Survey, No. 375. 



Leaves rather thick, obtuse, with the revolute margins hispidly 

 ciliate; lower ones 10 hnes long, 1 to 2 lines wide, with one or two 

 strong teeth on either edge ; upper ones entire, and gradually reduced 

 to bracts. Fruit and pedicel together 8 lines long, subterete, strongly 

 4-costate. Inflorescence racemose, or in older specimens in a con- 

 tracted panicle.
