Brickellia scoparia (DC.) Gray, var. subauriculata, var. nov., 

 foliis basin versus paulo ampliatis ad 7 mm. latitudine subauriculatis, 

 auriculis brevissimis rotundatis, margine revolutis. — Hills of Zacatecas, 

 Mexico, 25 October, 1888, Pringle, no. 1766 (type, in Gray Herb.); 

 also en route from San Luis Potosi to Tampico, December, 1878, to 

 February, 1879, Palmer, no. 1077. The hitherto unpublished herba- 

 rium name of this variety has been on some plant-labels attributed to 

 Dr. Gray, but this seems to have been an error. So far as can be as- 

 certained from the material and records at the Gray Herbarium, Dr. 

 Gray regarded Palmer's no. 1077 as typical B. corymbosa, and the 

 Pringle plant was not collected until after Dr. Gray's death. Under 

 these circumstances it seems undesirable, as it is unnecessary, to em- 

 ploy a parenthetical authority in this case. 



Kuhnia adenolepis, sp. nov., perennis, caulibus saepe 2 gracilibus 

 e caudice lignescenti oriuntibus erectis summa parte minutissime pube- 

 rulis 6-8 dm. altis teretibus obscure striatulis purpureis ; foliis alternis, 

 infimis ante anthesin delapsis, intermediis anguste lanceolatis integer- 

 rimis louge attenuatis 6-7 cm. longis 7 mm. latis saepe falc9.tis paten- 

 tibus utrinque viridibus glabris puncticulatis basi 3-nerviis ; foliis 

 superioribus gradatim minoribus, eis ramorum floriferum parvis line- 

 aribus ; capitulis paucis 2-3 in ramis gracilibus elongatis bractiferis 

 solitariis terminalibus erectis vel leviter nutantibus 12-13 mm. diame- 

 tro 18 mm. altis ca. 10-r2-floris ; involucri squamis viridibus albido- 

 striatis multiseriatim imbricatis, saltim exterioribus cum gland ulis 

 nigresceutibus subsessilibus eleganter ciliolatis ; corollis gracilibus 

 apicem versus atropurpurascentibus, dentibus limbi brevissimis sub- 

 erectis ; styli ramis nigresceutibus clavellatis conspicue exsertis ; pappi 

 setis valde plumosis leviter fulvescentibus. — Chapala Mountains, near 

 Guadalajara, Mexico, 13 December, 1889, C. G. Pringle, no. 2933 

 (type, in Gray Herb.). A species of graceful habit and seemingly 

 unique in its curiously glandular-ciliolate involucral bracts. 



LiATRis TENUIFOLIA Nutt., var. laevigata (Nutt.), comb, nov., quam 

 forma typica conspicue robustior ; foliis 4-8 mm. latis coriaceis; capitulis 

 saepe sed non semper paulo majoribusetiam ad 9 mm. longitudine. — 

 L. laevigata Nutt. Trans. Am. Phil. Soc. vii. 285 (1840). L. tenuifolia 

 Nutt. /5 Torr. & Gray, Fl. ii. 70 (1841). Lacinaria laevigata (Nutt.) 

 Small, Fl. S. E. U. S. 1175 (1903). Laciniaria laevigata (Nutt.) Small, 

 1. c. 1339. — To this variety may be referred Mr. Nash's nos. 1669 and 

 2599 from Eustis, Florida, while Prof. Hitchcock's no. 154 from Marco, 

 Florida, represents a transition to the more slender typical form. It is
