POPPY FAMILY

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

 Humboldt Bay, Tracji 2046; Olema, Jeitson 8283; Ingleside, Jcpson 2 i28. 



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

 in tlie soutliorn 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. liorridufus Greene and P. villosus Greene. Continuous intergrades are represented by spms. 

 from Ft. Tejon, Eall G290, Calient*, Kern Co., Jrpsoii 6756, Caliente Creek, Davy 1934. 



II. Variation in EEPRODUCTrvE organs 



1. Oalj-x. («) The flower buds are commonly obovoid but sometimes globose. The globose 

 character is not definitely correlated with other characters, (b) 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 liairy (Spring\'ille, Tulare Co., Purpus 1749)., There 

 aro regular intergrades from these extreme states to the ordinary fonn. 



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 : 

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

 base, (b) The petals are yellow throughoiit: sand dunes. Little Kiver beach (Humboldt Co.), 

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



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

 tlie same as Tracy 2034, same loc, petals creamy white through- 

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

 Ball cf- liahcDck 5016. (c) The petals are white with definite yellow 

 blotch at base : Poso Creek, Hall # Babcncl- 5018. (/) The petals are 

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

 Creek, Hall tf Babcork 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. (/^) The 

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

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

 Cf. P. purpurat us Greene; P. anfoiiiinis Greene; P. obtcctus Greene 

 var. sanctaruin Greene. The petals are normally entire; how'ever 

 in spms. from near the coal mines bet%v. Antioch and Marsh Creek, 

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



3. iStamcns. The filaments are usually dilated, tlie outer ones 

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

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

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

 same collection have narrow'er filaments which are not 3-toothed. 

 Cf. P. hctcrandcr Greene and P. subercus Greene, (b) The outer 

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

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

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

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



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

 tendency to produce two or three distinct pluricarpellary circles, 

 the fruiting carpels being extremely hairy (especially when imma- 

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

 rounded but aro more or less cylindric: Riverside, Brandcgee <f- 

 Wilder: Marysville Buttos, Heller 11246. In other cases the fruits 



have the beads well rounded : Coahuilla Valley, Riverside Co., Jcpson 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 

 Vallev, e. San Piego Co., Jcpson 8734; Hog Cauon, San Bernardino Valley, Parish 5746 (in 

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

 extra circles of non-hairy fruits are likewise teratological. (c) Many specimens have torulo.se 

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

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

 4' IVilder 2: Botanic Garden, Berkeley, plants from Lake Merced (San Francisco) seed, K. 

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

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

 torulose and breaking into 1-seedei] joints (ex. cluir.). (d) Moniliform carpels, usually glabrous 

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

 San Franci.sco, K. Brandcgee 5p, 6p, 7p; betw. Antioch and Marsh CVeek, K. Brandcgee. (e) 

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

 seed, but conspicuously liairy (as often in c) : Ocean View, San Francisco Co., K. Brandcgee
