This species is related evidently to C scorzonerifolia, IIBK., but 

 differs in being glandular-pubescent throughout with longer hirsutish 

 hairs intermixed, in having shorter narrower leaves, somewhat smaller 

 flowers, and in having the upper floral bracts as well as the calyx-lobes 

 orange- to scarlet-colored. From C. Uthospermoides, HBK., with which 

 it has been confused also, it differs in having the leaves more dilated at 

 the base, the upper stem-leaves more attenuated, in being less hispid, and 

 finally in having an ovate acuminate capsule. 



Castilleja hirsuta, Mart. & Gal. Bull. Acad. Brux. xii. pt. 2, 29 

 (1845); Walp. Rep. vi. 651; Hemsl. Biol. Cent.-Am. Bot. ii. 4G0. C.ob- 

 ovata, Beuth. DC. Prodr. x. 528 (1846). To this species are referred 

 specimens collected by Mr. C. G. Pringle in a barranca below Trinidad 

 Iron Works, altitude 1525 m., 13 June, 1904, no. 8935 (hb. Gr.). Mr. 

 Pringle's specimens agree well with the original characterization of the 

 species except there is a tendency for the leaves to become incised-dentate 

 or laciniate. 



Lamourouxia brachyantha, n. sp. Stem about 1 m.high, branched 

 above, yellowish green, somewhat hirsute below, densely stipitate-glaudu- 

 lar above : leaves sessile, oblong-lanceolate to ovate, 1 to 3 cm. long, 

 0.5 to 1 cm. broad, acute, sharply and somewhat unequally dentate, half- 

 clasping the stem, glandular-hirtellous on both surfaces : inflorescence 

 racemose-paniculate ; bracts of the inflorescence similar to the stem- 

 leaves but smaller : flowers in anthesis 2 to 2.5 cm. long, short-pedi- 

 cellate : pedicels 3 mm. long: calyx about 12 mm. long, 4-lobed to the 

 middle ; lobes ovate, acute, unequally dentate, aud as well as the pedicels 

 glandular-hirtellous : corolla 18 to 20 mm. long, bilabiate ; posterior lip 

 or galea conspicuously hooded, overarching the stamens, 2-lobed with the 

 lobes soon becoming reflexed ; lower or anterior lip recurved, 2-plicate- 

 ventricose in the throat, 3-lobed with oblong rounded lobes : stamens 

 4, fertile ; the posterior pair with smaller anthers : ovary glabrous below, 

 above as well as the persistent style pubescent : capsule ovate, short- 

 acuminate, about 1 cm. long. — Mexico. State of Mexico : rocky hills, 

 Lecheria, Valley of Mexico, altitude 2285 m., 1 July, 1904, C G. Pringle, 

 no 8815 (hb. Gr.). This species belongs to the § Hemispadon, Beuth., 

 and according to the revision of the genus by Robinson and Greenman 

 in the American Journal of Science 1. 169, it should be placed next to 

 L. rhinanthifolia, IIBK. The short corolla with its strongly hooded 

 galea combined with the ovate dentate calyx-lobes serve to distinguish 

 L. brachyantha from all other known species of the genus. 



Hygrophila Pringlei, u. sp. Stems simple or branched, 6 to 10 dm.
