CATALOGUE OF SPECIES. 159 



1883); Mineral Park, Mohave County, Arizona (Mr. and Mrs. Lemmon, June, 1881); 

 Yucca, Arizona (Jones, 1884) ; and Mount Trumbull, Arizona (Palmer, 1877, Noa. 3311 

 and 3342). 



Phacelia ivesiana Torr. Bot." Ives Exp. 21 (1860). Type localities, "Diamond 

 River," northwestern Arizona; "sandy hills, Oray be, "northeastern Arizona; "banks 

 of the Colorado," at Pyramid Canon. 



In the Vegas Wash, Nevada (No. 421), and near Hot Springs, Panamint Valley 

 (No. 684). Specimens from Oregon, Washington, and Idaho, which have been 

 referred to this species, do not belong to the typical form of it. In geographical 

 range, therefore, the plant is conlined to the arid Lower Sonoran region of Arizona, 

 Utah, Nevada, and California. 



Phacelia lemmoni Cray, Syn. Fl. ii. pt. i. 417 (188G). Typo locality, "N. W. 

 Arizona, on plains, at Mineral Park." 



In the Vegas Wash, Nevada (No. 1893), opposite the gypsum cliffs. The corollas 

 of these plants are purple instead of white, as in the type specimens. 



Phacelia magellanica (Lam.) Joura. I list. Nat. i. 373 (1787), under Hydrophyllnm. 



The name Phacelia circinata must be replaced by P. magcllanica. The specific 

 name circinaia was originally published in 1813 1 as "Aldceea circinata" with a note 

 by Schleehtendal: "Planta haec sub nomine Heliotropii pimiati et Hyilrophylli 

 magellanici nota est. Celeberrimus Willdenow earn ad novum hocce genus imiau- 

 dovit, eujus illustrationem inchoatam mors praematura interrupit." The question, 

 therefore, whether Aldea circinata is identical with Hydrophyllnm magellanicum does 

 not arise, for the former was founded upon the latter. The date of publication of 

 Heliotropium pinnatum is 1794. The case is therefore one of clear priority of the 

 specific name magellanica, but the plant of South America may not be identical with 

 that of the Tinted States, and the name magellanica applicable, therefore, only to 

 the former. 



In No. 1739, from Waueoba Canon, Inyo Mountains, the leaves are densely canes- 

 eent with appressed, hispid hairs, while No. 1551, from nearly the altitude of tim- 

 ber-line in the Sierra Nevada, is appressed-hispid, but green. 



Phacelia pachyphylla Gray, l'roc. Anier. Acad. six. 88(1884). Type locality, 

 "dry alkaline lakes near Calico Mines, Mohave Desert," California. 



In Furnace Creek Canon (Nos. 216, 357, 455), Johnson Canon (No. 567), and Sur- 

 prise Canon (No. 703). 



Our specimens differ from the ones that have been collected heretofore in their 

 uniformly much larger corolla and correspondingly longer filaments and styles. 

 The corolla is purple, 10 to 15 mm. long, and of about the same breadth. If this char- 

 acter is constant the plant should constitute a new species, but it is possible that 

 under different conditions of moisture the size of the corolla may vary widely. 



Phacelia pedicellata Gray, Syn. Fl. ii. pt. i. 160 (1878). Type locality, "Lower 

 California." 



In the Funeral Mountains, between Ash Medows and Furnace Creek (No. 436). 

 Our specimens have attained a height of 28 to 40 cm., have stout, brandling, brittle 

 steins, sometimes 1 cm. thick at the base, are densely glandular-hairy, when fresh 

 have the rank odor of crushed onions, and, while drying, gave the characteristic 

 brown stain of Phacelia more abundantly than did any other species. The pub- 

 lished description of the leaves may be somewhat extended. They are oblong 

 in outline, pinnatoly compound with 3 to 9 oblong pinnae, the lower, in the fully 

 developed leaves, stalked and lyrately pinnatifld into 2 to 5 lobes. The upper pinnae 

 are sessile and often confluent, while all are doubly pinnatifid-crenate.
