There is very little doubt that this is the plant Doctor Gray had before him, not- 
withstanding that the name applies much better to some of the other species. There 
is also little doubt that this is a plant which Doctor Torrey included in his H. dentata 
in the Botany of the Mexican Boundary Survey, a reference in which others have 
followed him, although the two plants are very unlike. The leaves of H. oblongifolia 
are not oblong; the lower cauline leaves are ovate to elliptic, acute and decurrent, 
entire, with occasionally a few inconspicuous teeth; the upper ones are lanceolate and 
acute. Doctor Gray calls attention to these facts in the descriptions cited above.

We have not seen types of either H. sancta Small or H. ciliata Nutt. and can not be 
sure that they are the same plant. What we take to be H. sancta seems to be the 
common plant of this genus in the region about Santa Fe, the type locality of the 
other species, and is reported by Doctor Rydberg from southern Colorado. Through 
the kindness of Dr. J. H. Barnhart we have learned that there is every reason to be- 
lieve that H. ciliata Nutt. was published a short time before H. ciliata Benth. Thus 
H. ciliata Nutt. would seem to be the proper name for the Santa Fe plant, with H. 
sancta as a synonym, providing Doctor Rydberg and we have been correct in referring 
this southern Colorado and northern New Mexico plant to the latter species.
