7. Hymenopappus luteus Nutt. Trans. Am. Phil. Soc. (II.) 7:
374- 1841
Dr. Gray in his Synoptical Flora referred this species to H.
filifolius, which, however, does not fit Nuttall’s description. Many
years before he had named Fendler’s specimens H. luteus. These
agree fairly well with Nuttall’s description, except as to the pap-
pus, which in them is much more prominent than in any of the
other species. Nuttall States that the scales of the pappus of H.
luteus are very short and hidden by the hairs of the achenes.
In 1897 Prof. Aven Nelson collected a Hymenopappus on
Green River, which he intended to describe as new, especially as
the type specimen was without pappus. A closer examination re-
vealed, however, that some of the specimens really had some
small scales. These agreed perfectly with Nuttall’s description..
Nelson’s specimens and my own, collected two years before, also
on Green River, are the only ones that perfectly agree with Nut-
tall’s description of H. luteus. His type $yas collected on thé
Ham’s Fork of the Colorado of the West. What the present
naipe of Ham’s Fork is or its exact location I have been unable
to find ; but from the route that Nuttall took it is undoubtedly
some stream of the Green River system.
