MicHoacan or GUERRERO: at 1500 metres altitude in the Sierra 
Madre, January 20, 1899, Langlassé, no. 767 (type, in Gray Herb.). 
A handsome species nearest related to S. Rose 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 
2m. alta; ramis glabris rufescentibus ; foliis crassis coriaceis glabris ~

longis cymulas item semel vel bis trichotomas 2—7 em. 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-

or GUERRERO : in granitic soil at 1800 m. altitude, Sierra Madre, Feb- 
ruary 10, 1899, Langlassé, no. 854 (type, in Gray Herb.). Closely re- 
lated to H. 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.
