character of which must be slightly modified to receive it. The calyx is 5-parted and the 

 narrow upper lip of the corolla is eraarginate. The anther-cells are nearly parallel and placed 

 one above the other ; the lower one conspicuously mucronate, and the upper one less so. No. 

 1213 of Coulter's Mexican collection is apparently an undescribed species of this genus.

 Plant 3-4 feet high, entirely leafless where found by Mr. Thurber, but it may bear leaves 



early in the season. Flowers sessile in unilateral spikes, without either bracts or bracteoles. 

 Calyx at first somewhat pubescent, but at length nearly or quite sniooth. '^Corolla scarlet/' 



an inch or more in length; the tube slender; lower lip deeply 3-parted, the divisions linear 

 and narrow. Capsule ovate above the middle, tapering to a narrow base below; 2-seetled. 

 Besides the four species of Drejera here described, we have, from the collections of Dr. Gregg, 

 anotlier, which does not appear to have been noticed hitherto. It was found on the battle field 

 of Paso del Gallinero. The specimens are not sufficient for a full description, but the following 

 character will serve for its identification : 



Drfjera Greggil (n. sp.) : ramis bifariam pubescentibus ; foliis ovatis scabriuscule pubssccn- 

 tibus subulato-venosis ; floribus fasciculatis foliis longioribus; calyce incano pubescente, lobis 

 lanceolatis tubo subfequalibus. A stout shrub. Leaves 1-1^ inch long, somewhat roughly 

 pubescent on both surfaces ; petioles 1-2 lines long. Flowers dull purplish red, 1 J inch long ; 

 the segments of the lower lip nearly as long as the tube, and very narrow. Fruit not known.

 States, common; flowering throughout the summer. (No. 1458, IFH^A^, 396, 1850, and 501,1815, 



Lindheimer. Plant C to 12 inches high, sufFruticose, much branched. Leaves half an inch to 



one and a half inch long. Flowers three-fourths of an inch long, pale purple. This plant is 



not a Monechma, for the capsule is 4-seeded, and the habit is different. It is still further removed
