form in essentials, altliough tlie short branches are sometimes much congested, (b) It varies 

 slightly in villosity; a state slightly more villous than the usual form is Navarretia hirsutissima 

 Brand. No form of Navarretia atractyloides is, however, set off by a distinctive pubescence char- 

 acter, (c) The corolla is usually purple, though occasionally white or yellow (var. flavida Jepson), 

 which are not exceptional color variations amongst Polemoniaceous annuals, (d) The leaf de- 

 velops marked eccentricities but the eccentricities lie within the limits of a fairly definite type. 

 The leaf may vary much in one particular, namely in breadth, even on one individual ; the body or 

 raehis varies from 1 to 4 lines in breadth and bears fine or coarse teeth or lobes, or it may be 

 filiform with filiform lobes ; but with all this the subulate or aristate or lanceolate or spiny lobes 

 follow a rather constant pattern. A special leaf form is discussed below. The preponderance of 

 fundamental resemblances and the unimportant character of differences makes Navarretia atrac- 

 tyloides one unit as here described.

A marked but inconstant leaf form is var. hamata (Greene) Jepson: leaves mostly small, 

 the raehis varying from filiform to 1 line broad with spreading spines, the three terminal spines 

 divaricate or often spreading horizontally. — It occurs within the range of the species as follows : 

 Judsonville, Contra Costa Co., K. Brandegee ; Pacific Grove, Heller 6782 (passing into the ordi- 

 nary form) ; Oak Park, San Luis Obispo, E. P. Vnangst; San Marcos Pass, Santa Ynez Mts., 

 Hoffmann; Santa Catalina Isl., T. Brandegee ; Eainbow, San Diego Co., Parish 4466; Escondido, 

 Chandler 5353; Del Mar, San Diego Co., Jepson 1609; San Diego, Orcutt 1454. The two first cited 

 specimens show leaf forms intermediate to the usual leaf form. Plants from the Pajaro Hills, 

 n. Monterey Co., Chandler 378, exhibit both the leaf types usual to N. atractyloides and that leaf 

 type characteristic of var. hamata, even on one individual. The plants from this station are 

 worthy of comment in that the ovate spiny-margined base of the leaf is contracted at apex into 

 a narrow peduncle-like process which bears at apex a circle of 3 horizontally divergent spines 

 equally spaced. So much for the variable var. hamata. Contrariwise, collections referable to 

 N. atractyloides may bear occasional leaves with the shape and spine-pattern of var. hamata.

22. N. viscidula Benth. (Fig. 377.) Stem erect, divaricately or somewhat 

 proliferously branched, sometimes spreading or subprostrate, sometimes dwarfish 

 and simple, 1 to 8 (or 10) inches high; herbage viscid-pubescent; leaves % to 2^2 

 inches long, narrow, the lower with slender or filiform raehis and remote filiform 

 lobes, the upper with broader raehis and remote short-subulate lobes; bracts little 

 dilated, palmately parted, the lobes incisely toothed or entire, or ovate with 1 or 2 

 laciuiate teeth on each side; calyx-lobes entire (very rarely the longer lobe with 

 one tooth), the longer lobes as long or longer than the calyx-tube; corolla blue- 

 purple or rose-purple, rather large (5 to 7 lines long) , l^/^ to 2 times as long as the 

 calyx, the limb 2 lines broad, its lobes elliptic; stamens exserted from coroUa-throat ; 

 capsule-cells 1 to 6-seeded.
