ally somewhat resembling Gardoquia mexicana, but with the definitely 

 bilabiate lip of Calamintha. 



Cunila tornentosa. Stem tall (probably 8 dm. high), sharply quad- 

 rangular, freely paniculate-branched, densely tomentose above and on 

 the younger parts: leaves lanceolate to ovate-lanceolate, acuminate, 

 sessile of short-petioled, entire or sparingly appressed-serrate, above 

 puberulent, beneath densely white-tomentose, 2 to 5 cm. long, 1 to 1.5 cm. 

 wide : racemes dense, spiciform, 1 to 4 cm. long, solitary or in o's, ter- 

 minating the short branches: pedicels slender, about equalling the calyx : 

 calyx 2 to 3 mm. long ; the tube twice or thrice as long as the lance-sub- 

 ulate teeth, densely villous especially within the throat : corolla villous, 

 slightly exceeding the calyx : stamens mostly included. — Oaxaca, 

 between Pluma and San Miguel Suchistepec, alt. 1,850 m., March 21, 

 1895 (E. W. Nelson, no. 2495). 



Hyptis (Cephalohyptis) madrensis. Stems procumbent, puberu- 

 lent (densely short-pilose-hirsute on the younger parts), freely brandling ; 

 iuternodes 0.5 to 1 dm. long : leaves thickish, oblanceolate to elliptic- 

 obovate, coarsely crenate-dentate above, the subcuneate entire base nar- 

 rowed gradually to a short petiole, appressed-pilose on both faces, dark 

 green above, pale beneath, 2.5 to 5 cm. long, 1 to 2 cm. broad : peduncles 

 axillary, 3 to 5 cm. loug: fruiting head 2 cm. in diameter : bracts folia- 

 ceous, lanceolate to oblong, eutire or coarsely dentate, I cm. or less long : 

 calyx villous, the long subulate teeth setulose. — Tepic, foothills of the 

 Sierra Madre, near Pedro Paulo, Aug. 3, 1897 (J. N. Rose, no. 1958). 

 Resembling, apparently, II. Parkeri, Benth., of South America but dif- 

 fering from that in its pubescent leaves and calyx. 



H. (Minthidium) Pringlei. Stem 1 m. (?) high, freely branching, 

 more or less pubescent with pilose or somewhat strigose hairs: leaves 

 lanceolate, acute, subsessile or short-petioled, entire, essentially glabrous, 

 2 cm. or less long : flowers axillary, 2 to G in a fascicle: pedicels slender, 

 glabrous, becoming 2 mm. long in fruit: calyx glabrous, campanulate, in 

 anthesis 1.5 mm., in fruit 3 to 4 mm. long, cleft one-third to the base 

 into narrowly deltoid subacuminate lobes: corolla slightly exceeding the 

 calyx. — San Luis Potosi, Tamasopo Canon, Aug. 5, 1890 ( 0. G. 

 Pringle, no. 3223). Related to H. verticillaris, with which it has been 

 confused, but with axillary flowers. 



H. (Minthidium) axillaris. Similar to the preceding: leaves lan- 

 ceolate or rhombic-lanceolate, 7 cm. or less in length, acuminate, coarsely 

 and irregularly serrate above the middle, entire below and cuneate to 

 petioles 1 cm. or less long, puberulent above, pilose beneath on the
