RYDBERG: Rocky MOUNTAIN FLORA 327 
macrophylla. In the latter the outer involucral bracts are elon- 
gated and reflexed; the former has the involucre*of B. Careyana 
with appressed bracts. I doubt that B. terebinthacea is found east 
of northwestern Idaho. 
It is a kind of puzzle to me, to determine what rule Professor 
Nelson followed in making these reductions. The specific name 
terebinthacea (1833) is much older than macrophylla (1841), and even 
where Nuttall transferred the former from Heliopsis to Balsamor- 
rhiza it has page priority. If united, B. terebinthacea should be 
the species and B. macrophylla the variety. 
Balsamorrhiza floccosa Rydb. and B. tomentosa Rydb. were 
reduced to synonyms of B. incana and B. sagittata respectively. 
It may be admitted that they (especially B. tomentosa) are closely 
related to the species to which they are referred, but I doubt 
if the authors of the New Manual have seen authentic material of 
either. Inthe Bulletin of the Torrey Botanical Club, November, 
1900, I gave a synopsis of the Rocky Mountain species of this 
genus, and have not found any material change to make since that 
time. 
“Gymnolomia linearis sp. nov. 
Perennial with a rootstock or slender caudex; stems 3-4 dm. 
high, terete, strigose; leaves opposite, short-petioled, narrowly 
linear, 3-4 cm. long, 2-4 mm. wide, entire, hirsutulous, indistinctly 
3-nerved, sparingly hispid-ciliate at the base; heads long-pedun- 
cled; involucres about 6 mm. high, 12-15 mm. broad; bracts 
linear-lanceolate, canescent-strigose; rays 10-12 mm. long, 3-4 
mm. wide 
This species resembles Gymnolomia longifolia and G. annua in 
leaf form and general habit, but it isa perennial. From G. multi- 
flora it differs in the narrow leaves and the slender perennial base, 
which would be classified rather as a rootstock than a caudex. The 
type number was included in G. multiflora by Robinson and Green- 
man* as a narrow-leaved form. The other specimens cited by 
them as belonging to this form, I have not seen, but probably 
they should be included in G. linearis.
