Helianthella scabra, n. sp.—Stems several, 6-8 dm. high, 
from a woody, perennial root, somewhat cymosely branched 
above and bearing many rather small heads: leaves dark green, 
coriaceous, prominently nerved, linear-lanceolate at base to nearly 
linear in the inflorescence, hispidulous-scabrous (occasionally 
glabrate above), acute or obtuse; radical leaves 15-25 cm. long, 
attenuate into a petiole two-fifths the length of the blade; cauline 
5-1ocm. long, short-petioled to sessile, first pair opposite: 
peduncles whitened with minute pubescence; involucral bracts 
more or less pubescent, in about three series, mostly lanceolate 
and shortly acute; ray flowers 8-10, neutral ray flowers bearing 
orange-yellow ligules over 1 cm. long, oblong, entire or cleft at 
apex, somewhat recurved; disk flowers purple with pubescent 
teeth; chaffy bracts of involucre nearly equaling disk, truncate 
and ciliate pubescent at apex: pappus of several short. lacerate 
squamellae and two awnlike elongated ones; achenes flattened 
but scarcely winged, from densely long pubescent in the marginal 
flowers to sparsely pubescent in central ones. 
This species seems to be most closely related to the little known H. micro- 
cephala Gray; from it, however, it is apparently easily distinguished by the 
very much larger size, the relatively longer ligules, and the different character 
of the pappus of the new species. Collected at Naturita, August 11, 1914, 
where it grows in gulches and ravines; no. 591. 
CHAENACTIS SCAPOSA Eastwood (Chamaechaenactis scaposa 
[Eastw.] Rydb.).—Nos. 267 and 305 of my collection may best be 
referred to this species, at least until more is known of the variability 
of C. scaposa. My plants differ principally from the type as 
described by Miss Eastwoop in having leaves that are pubescent 
but not at all hirsute on the upper surface; pappus that is qudle as 
long as the achene; and an achene that is appressed long-pubescent 
rather than villous. The original description does not mention 
the existence of rows of many small, superficial dark dots on the 
achene such as the Naturita specimens possess. Collected on 
gypsiferous hillsides, April 30 and May 15, 1914. It is interesting 
to note that the flowers of this plant have a peculiar, “heavy” 
fragrance that reminds one somewhat of Abronia fragrans.
