Gray, Fl. 9. p. 41. Var. corollis minoribus. — Rocky soil 
on the plateau above New Braunfels. June. 
(621.) Hepyorts (HovsrowiA) Humrrusa (n. sp.): annua, 
dichotome ramosissima, depressa, glutinoso-puberula ; foliis 
lineari-lanceolatis imis in petiolum attenuatis mucronatis 
crassiusculis ; stipulis dilatatis scariosis setaceo-dentatis ; flori- 
bus in dichotomiis solitariis binisve breviter pedunculatis ; 
tubo coroll: infundibuliformis lobis oblongis supra puberulis 
sublongiore lacinias calycis 4-partiti subulato-setaceas paulo 
supérantibus ; capsula pendula didyma puberula basi tantum 
calyci accreta ; seminibus in loculis paucis ovoideis. — Open 
gravelly banks of streamlets, near Fredericksburg. May. 
' (Also in sandy prairies at Austin, Mr. Charles Wright.) — 
Stems 3 or 4 inches long, fastigiate, very leafy, in cultivation 
(in the Cambridge Botanic Garden) close pressed to the 
ground, and forming a dense patch, flowering through the 
simmer. Lower leaves somewhat spatulate, an inch long; 
the others linear and smaller. Corolla pale purple or nearly 
white, 3 lines long; the lobes more or less downy inside. 
Stigma two-lobed. The flowers are dicecio-dimorphous, after 
the manner of the genus and its allies; one plant having the 
linear anthers deeply included, and a long style with the 
stigma exserted; the other with a short, included style, and 
with the stamens inserted in the throat of the corolla. Both 
forms are abundantly fertile. The seeds are not hollowed on 
the inner face. — 'T'his species is intermediate in characters 
between Houstonia, Amphiotis, and Ereicotis, and should 
perhaps stand in a separate section, along with H. rubra, 
although the latter is in some respects quite a different plant. 
I was mistaken in stating (in PI. Fendl. p. 61), that H. rubra 
had been met with in Texas. No. 621 is the form with sub- 
exserted stamens, and short style. 
(622.) The same species with subexserted style and 
included stamens. Sandy prairies on the Pierdenales. May.
