2. Tendency to strong foliation. Plants in sandy or moist soils show luxuriant leafy stems : 

 Humboldt Bay, Tracy 2046; Olema, Jepson 8283; Ingleside, Jepson 2328. 



3. Tendency to extreme crinitism. Plants of the interior towards the south, especially 

 in the southern Sierra Nevada and neighboring ranges, show a tendency to extreme hairiness 

 of stems, buds or fruits (especially when young) : Springville, Tulare Co., Purpus 1749. Cf. 

 P. Iwrriduluft Greene and P. villosus Greene. Continuous intergrades are represented by spms. 

 from Ft. Tejon, Hall 6290, Caliente, Kern Co., Jepson 6756, Caliente Creek, Davy 1934*. 



II. VARIATION IN REPRODUCTIVE ORGANS 



1. Calyx, (a) The flower buds are commonly obovoid but sometimes globose. The globose 

 character is not definitely correlated with other characters, (ft) The usual form of calyx is 

 moderately pilose with somewhat scattered hairs; sometmes it is very hairy (Erskine Creek, 

 Kern Co., Purpus 5000) or excessively hairy (Springville, Tulare Co., Purpus 1749). There 

 are regular intergrades from these extreme states to the ordinary form. 



2. Corolla. The corolla is commonly saucer-shaped but is sometimes rotate or turbinate 

 at base. The petals are commonly cream color. The following color variations may be noted: 

 (o) A deeper or yellow color occurs at apex, with this color sometimes repeated as a spot at 

 base. (&) The petals are yellow throughout: sand dunes, Little River beach (Humboldt Co.), 

 Tracy 4797. (c) The petals are sometimes lemon yellow with white 



base: Humboldt Bay, Tracy 2020 (which is, save for color, exactly 

 the same as Tracy 2034, same loo., petals creamy white through- 

 out), (d) The petals are pure white: Poso Creek, Greenhorn Range, 

 Hall $ Babcock 5016. (e) The petals are white with definite yellow 

 blotch at base: Poso Creek, Hall $ Babcock 5018. (/) The petals are 

 white with definite yellow blotch at base and another at tip: Poso 

 Creek, Hall fy Babcock 5069 (the three preceding numbers of Hall 

 & Babcock differ only in color of petals), (g) The petals are 

 sometimes deep rose pink outside on the upper half. (7i) The 

 petals are reddish tipped in spms. from Priest Valley, se. Monterey 

 Co., Jepson 2687, but a dupl. sheet shows the normal cream color. 

 Cf. P. purpuratus Greece; P. antoninus Greene; P. obtectus Greene 

 var. sanctorum Greene. The petals are normally entire; hoAvever 

 in spms. from near the coal mines betw. Antioeh and Marsh Creek, 

 K. Brandegee, some of them are weakly lobed, especially the outer. 



3. Stamens^ The filaments are usually dilated, the outer ones 

 broader than the inner (fig. 111). The following variations may 

 be noted: (a) The filaments are very broad and 3-toothed at 

 apex in a plant from Tiburon, K. Brandegee, but other plants in 

 same collection have narrower filaments which are not 3-toothed. 

 Cf. P. heterander Greene and P. subereus Greene. (6) The outer 

 filaments 'are moderately broad: Pt. Richmond, Hall 1654, and 

 Ocean View, San Francisco Co., K. Brandegee (in the latter the 

 outer filaments are obcordate or retuse). In many specimens the 

 outer filaments are often 2-toothed with the inner filaments entire. 



4. Carpels: (a) Many specimens have flowers showing a 

 'ondencv co produce two or three distinct pluricarpellary circles, 

 tie ^raiting carpels being extremely hairy (especially when imma- 

 ture). In some such specimens the beads of the fruit are not well 

 rounded but are more or less eylindric: Riverside, Brandegee $ 

 Wilder; Marysville Buttes, Heller 11246. In other cases the fruits 



have the beads well rounded: Coahuilla Valley, Riverside Co., Jepson 1470. Such double or 

 triple circles of carpels are teratological and are borne on plants with single or normal circles 

 and often show intergrade states. (&) Other specimens have flowers showing a tendency 

 to produce two distinct pluricarpellary circles, the fruiting carpels not at all hairy: San Felipe 

 Valley, e. San Diego Co., Jepson 8734; Hog Canon, San Bernardino Valley, Parish 5746 (in 

 one flower there are 3 carpellary circles) ; Oeeanview, San Francisco, K. Brandegee lOp. Such 

 extra circles of non-hairy fruits are likewise teratologicaL (c) Many specimens have torulose 

 carpels which are empty or 1 or 2-seeded and hairy (sometimes densely so) : Bardin's Switch 

 betw. Castroville and Monterey, K. Brandegee 2a, 2b, 2d, 2f , 2p, 3p, 4p ; Riverside, Brandegee 

 $ Wilder 2; Botanic Garden, Berkeley, plants from Lake Merced (San Francisco) seed, K. 

 Brandegee (anthers apparently never producing pollen). Cf. P. capsularis Greene; carpels 

 seedless except externally, that is within the cavity formed by union of the carpels, rarely 

 torulose and breaking into 1-seeded joints (ex. char.), (d) Moniliform carpels, usually glabrous 

 or nearly so, are frequently found, each bead denoting the position of a seed: Ocean View, 

 San Francisco, K. Brandegee 5p, 6p, 7p; betw. Antioeh and Marsh Creek, K. Brandegee. (e) 

 Again we have specimens in which the types of carpels in c and d are present as to shape and 

 seed, but conspicuously hairy (as of ten' in c) : Ocean View, San Francisco Co., K. Brandegee
