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

 West's Creek, 18G4 ; also Cloverdale, Sonoma Co., and Eel River, &c. 

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

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

 if they belong to the 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 Klamath 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 acapisve gracilibus 1 - 2-pedalibus ; foliis lineari- 

 lanceolatis elongatis integerrimis imisve subdentatis nunc laciniatis ; 

 capitulis parvulis ante anthesin nutantibus; involucri squamis gradatim 

 imbricatis e lanceolata vel ovato-lanceolata attenuato-acuminatis ; ache- 

 niis breviter linearibus (vix basi hand apice angustatis) glabris vel 

 exterioribus puberulis ; pappi sordescentis paleis 8-9 brevibus ovato- 

 oblongis ex apice obtuso vel eroso-bidentato in aristam scabram 

 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 inches 

 lon£, 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 lines long, about thrice the length of the somewhat rigid palere of the 

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

 between Eucalais and Scorzonella.* 



Hieracium Bolanderi: H. venoso affine ; foliis omnibus radicali- 

 bus sessilibus spathnlato-oblongis vel oblanceolatis vix denticulatis infra 

 glaberrimis glaucescentibus (nunc purpureis) supra marginibusque pilis 



* Hypochjeris glabra, Linn., occurs in collections made by Dr. Kellogg and 

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

 Europe.
