glaucum, Hook. Fl. Bor. Am. Scorzonella glauca, Nutt. — At Mark 

 West's Creek, 1864 ; also Cloverdale, Sonoma Co., and Eel River, &c. 

 Mendocino Co., in moist meadows, 1866-7, Bolander. The size of 

 most of these specimens and the breadth of the leaves made it doubtful 

 if they belong to tiie species indicated by Sir Wm. Hooker; but a 

 comparison made by Prof. Oliver with the solitary specimen preserved 

 in the Hookerian herbarium (the leaves of which are not "canaliculate " 

 but only longitudinally folded) assures me that they do. The leaves in 

 the California plant are from 4 to 12 inches long, and from 1 to 2^ 

 wide, the midrib strong and broad. In specimens from Klamatli Co., 

 Oregon, Dr. Kronkrite, they are narrower, approaching to " linear- 

 acuminate," and the head scarcely larger than in S. laciniata. In 

 Bolander's, the larger heads are an inch in diameter ; the achenia fully 

 2 lines, and the pappus nearly half an inch in length. The Californian 

 forms in general, being remarkably stout and tall, and so broadly- 

 leaved, may be distinguished as var. procera. 



Calais Bolanderi: subscaposa e radice tuberoso-fusiformi ; cauli- 

 bus basi parce ramosis scapisve gracilibus 1 - 2-pedaiibus ; foliis linearl-

 achenio duplo longiorem productis. — Swamps at Fort Bragg, Mendo- 

 cino Co., Bolander. — Leaves 8-14 inches long (including the taper- 

 ing base or petiole), or those on the lower part of the stem 3-6 inciies 

 lonj^, 3 to 6 lines broad, more commonly entire; some denticulate or 

 coarsely toothed, or, in one specimen, laciniate-pinnatifid. Involucre 

 scarcely over half an inch in length. Achenia rather slender, barely 

 2 lilies long, about thrice the length of the somewhat rigid paleaj of the 

 pappus. The species is interesting from being, as it were, intermediate 

 between Eucalais and Scorzonella* 



HiERACiUM Bolanderi: H. venoso q,^x\q ; foliis omnibus radicali- 

 bus sessilibus spathulato-oblongis vel oblanceolatis vix denticulatis infra 

 glaberrimis glaucescentibus (nunc purpureis) supra marginibusque pilis 



* Htpocii^ris glabra, Linn., occurs in collections made by Dr. Kellogg and 

 Dr. Gibbons in the vicinity of San Francisco, perhaps recently introduced from 

 Europe.
