Michoacan or Guerrero : at 1500 metres altitude in the Sierra 

 Madre, January 20, 1899, Langlasse, no. 767 (type, in Gray Herb.). 

 A handsome species nearest related to 8. Rosei Fernald, but abun- 

 dantly distinct in the pubescence of its branches, calyx and corolla, 

 as well as the small calyx and the glabrous style. 



Hyptis (Hypenia§ Longiflorae) Langlassei, n. sp.,fruticosa circa 

 2 m. alta ; ramis glabris rufescentibus ; foliis crassis coriaceis glabris 

 lanceolatis acuminatis basi subcuneatis, superioribus 1-1.7 dm. longis 

 2-3.5 cm. latis acute dentatis ; panicula trichotoma ramis 1.5-2.7 dm. 

 longis cymulas item semel vel bis trichotomas 2-7 cm. longas laxe 

 patentes gerentibus, rhachi glanduloso-puberulo ; bracteis ovato-lanceo- 

 latis acuminatis integris puberulis, inferioribus 2.5 cm. longis, supe- 

 rioribus 1 cm. longis; pedicellis demum 4-11 mm. longis; calyce 

 campanulato anthesi 4-5 mm. fructifero 8-9 mm. longo glanduloso- 

 puberulo et glanduloso-hispido, pilis brevibus albidis squamosis ; labiis 

 patentibus lanceolato-aristatis ; corolla sanguinea puberula 2 cm. longa, 

 tubo infundibuliforme, galea 2-3 mm. longa lobis rotundis labiam inferi- 

 orem subaequante; staminibus stiloque exsertis glabris. — Michoacan 

 or Guerrero : in granitic soil at 1800 m. altitude, Sierra Madre, Feb- 

 ruary 10, 1899, Langlasse, no. 854 (type, in Gray Herb.). Closely re- 

 lated to //. Nelsoni Fernald, of the mountains of Jalisco, which has the 

 leaves broad and clasping at base, the pubescence much finer (that of 

 the calyx merely a fine puberulence), and the hardly aristate calyx-lobes 

 much shorter.
