incurvo retuso; inferiore patentissimo basi contracto trilobo, lobis 

 lateralibus rotundatis, medio latiore emarginato-subbilobo. Stamina 4, 

 inferioribus paullo longioribus didynama, sub labio superiore incurvo- 

 adscendens, fere parallela : anthera muticae, biloculares ; loculis sub- 

 parallelis connectivo transversim dilatato demum sejunctis basi fasci- 

 culo pilorum instructis. Stylus glaber, cruris subulatis sequalibus. 

 Nuculaa loeves, globosoe". — Suffrutex Rosmarini facie, ramosissimus, 

 tenuiter canescens, foliosissimus ; foliis angusto-linearibus margine revo- 

 lutis, in axillis nunc fasciculatis ; cymulis 2 - 7-floris laxis in axillis 

 subsessilibus ; corolla albo-purpurea extus pubescente; calyce fructi- 

 fero declinato, dentibus (rarius tubo) pilis patentissimis birsutis. 



Conradina canescens. Calami ntha canescens, Torr. & Gray ex 

 Benth. in DC. Prodr. 12, p. 229, & Chapm. Fl. p. 318. — Dry sands 

 along the beach and in pine woods of Western Florida, from Appala- 

 chicola to Pensacola and Mobile : called " Wild Rosemary." — A well- 

 marked genus in habit and character, much better distinguished from 

 Calamintha than is Ifelissa, in foliage, inflorescence, &c, not unlike 

 Dicerandra. The essential character is in the corolla, which is widely 

 ringent, and abruptly bent backwards on its tube. 



The genus is dedicated to the memory of Solomon W. Conrad, the 

 associate of Muhlenberg and the other Pennsylvanian botanists of the 

 last generation, the publisher of Muhlenberg's Catalogue and his 

 Descriptio Uberior Giaminum, &c, — himself a botanist of no mean 

 acquirements. Long ago the Gerardineous genus which now bears 

 the name of Macranthera, Torr., was dedicated to Mr. Conrad by Nut- 

 tall (in Jour. Acad. Philad. 7, p. 88) ; but the earlier-published Ges- 

 neriaeeous Conradia of Martius, in memory of Conrad Gesner, retains 

 this name. By means of a moderate change in the orthography, we 

 may arrange to connect the name of our American Conrad with this 

 striking plant of our own country. 



POLIOMINTFIA, Nov. Gen. Labiatarum. 



Calyx tubulosus, 13 - 15-nervius, striatus, aequalis, dentibus 5 a?qua- 

 libus, fauce annulato-villosa. Corolla tubo recto pi. m. exserto, intus 

 piloso-annulato ; limbo breviter bilabiato ; labio superiore erecto sub- 

 piano emarginato ; inferiore trifido patente, lobo medio emarginato- 

 bilobo. Stamina fertilia 2 (iuferiora), paralltle adscendentia, apice 

 nunc incurva, antheras loculis divaricatis : filamenta 2 superiora ste- 

 rilia brevissima. Styli cruri subinaaquales. Nuculae lseves. — Suffru-
