 oribus. — Rocky banks of the Sacramento below Mount Shasta, Cali-

AcTiNOLEPis Lemmoni. Tenella, laxe ramosa, triuncialis, lana 

 tenui floccosa decidua demum glabrata ; foliis parvis alternis fere linea- 

 ribus obtusis integerrimis caruosulis ; capitulis (lin. 3 longis) peduncu- 

 latis angustis ; involucro e bracteis 6-7 oblongis ; receptaculo piano ; 

 ligulis 4-6 lato-ovalibus tridentatis roseo-albis discum vix superan- 

 tibus ; acheniis clavatis hirsutis ; pappo nullo. — Mohave Desert, S. E. 

 California, on the borders of Arizona, Lemmon, 1880. 



Laphamia Lemmoni. Parva, ramosa, depressa, subcinereo-pu- 

 bescens ; foliis omnibus oppositis cordato-rotundis (cum petiolo fere 

 a^quilongo semipollicaribus) 5-7-lobatis incisisve nunc fere partitis, 

 lobis obtusissimis ; pedunculis capitulo baud longioribus ; involucri 

 bracteis lineari-oblongis vel subspathulatis obtusissimis subplanis ; 

 ligulis nullis ; corollis disci luteis ; styli ramis elongato-subulatis ; 

 acheniis compressiusculis pube brevi densa subcinereis ; pappo uni- 

 (raro bi-) aristellato stepe evanido. — Near Camp Lowell, Tucson, 

 Arizona, Lemmon, 1880. — Depressed-spreading, only 2 or 3 inches 

 high; the heads 4 lines high. The usually solitary bristle of the 

 pappus is exceedingly slender, about the length of the proper corolla- 

 tube and half that of the achenium ; rarely there are two contiguous 

 ones, in many flowers none at all or a mere rudiment. Assuming a 

 form with incisely lobed leaves as the type, a marked variety, sent under 

 a separate number, from the same station, is to be indicated, viz. : — 



Var. PEDATA. Foliis plerisque pedatipartitis vel bipalmatifidis. — 

 With the typical form.

 pollicem longis) obtusiusculis basi in petiolum attenuatis utrinque
