Pentach^ta Orcuttii. p. aurece subsimilis ; capitulis parvu- 

 lis ; involucro villoso-pubesceute, bracteis viridioribus ; ligulis bre- 

 vioribus ; pappi setis 8-10 capillaribus basi baud dilatatis caducis ! 

 — Vallecito, in the northern part of Lower California, C R. Orcutt, 

 May 4, 1886. 



Franseria camphorata, Greene, Bull. Calif. Acad. i. 192. Var. 

 LEPTOPHYLLA. Gracilior, tomento tenuissimo evanescente ; foliis 

 minoribus tenuisectis, lobis minimis. — Near San Fernando, Lower 

 California, Orcutt, 1886. The resinous atoms which give the bal- 

 samic odor are much more manifest than in Pahner and Greene's 

 type, the tomentum being minute and evanescent. The minute coat- 

 ing of stipitate glands on the fertile involucres well characterizes the 

 species. 



Verbesina dissita, Gray, Proc. Am. Acad. xx. 299. Fine flow- 

 ering specimens, from " La Grulla," sliow tlie species with larger heads 

 and more showy rays than was supposed, and require the following 

 modifications of the character: foliis papilloso-scabridis, superioribus 

 SiBpe alternis, inferioribus nunc basi lata sessilibus ; capitulis latis 

 semi- vel sub-poUicaribus ; involucro campanulato, bracteis obtusis, ex- 

 timis subspathulatis brevioribus, interioribus linearibus acutiusculis ; 

 ligulis 8-10 obovato-oblongis subpollicaribus liBte aureis. 



Gentiana linearis, Frcel., var. latifolia. Robusta ; foliis om- 

 nibus basi hand contracta arete sessilibus, imis oblongo-linearibus, su- 

 perioribus ovato-lanceolatis, summis flores capitatos involucrantibus : 

 appendicibus plicarum coroll^e latis aut acutatis aut subtruncatis lobis 

 ssepius dimidio brevioribus ; bracteis (etiam formae typic^e) nunc tenu- 

 issirae scaberulis. — Of G. lineai-is, var. lanceolata, it is said in the 

 Synoptical Flora that it " approaches narrow-leaved forms of G. albaP 

 The variety here characterized is the form from Lake Superior which, 

 in the work referred to, I had referred to G. alba, though there is no 

 proof that it has the yellowish-white corolla of that species ; and I 

 have some reason to suppose that it is also G. rubricauUs of Schweinitz 

 from the same region. It now comes to us from New Brunswick, ten 

 or twelve miles north of St. Stephen, in Charlotte Co., where it was 

 discovered in July and August last by Mr. J. Vroom and Mr. W. F. 

 Ganong, with flowers as blue as those of G. Saponaria (which has 

 quite different plicae), and with foliage like that of G. Andrewsii. 

 Although completely connecting forms are wanting, I must conclude 

 that we have here only an extremely broad-leaved variety of G. line- 

 aris. It was collected at Lake Superior first by Prof. W. D. Whitney ;
