556 PAPAVEBACEAE 



8p. (/) Sometimes we have very interesting specimens which bear on the same plant both 

 moniliform carpels with rounded beads and carpels in which the beads are short-eylindric 

 instead of rounded, aJl seed-bearing: San Diego (ocean cliffs), K. Brandegee Ip. Cf. P. 

 sphaerooarpus Greene, (g) In other cases the fruiting carpels are unusually long (9 to 11 

 lines), the carpels each with an obvious dorsal keel: Sutter plains, Jepson; Antioch to Marsh 

 Creek, near the coal mines, K. Brandegee a. Cf. P. emarginatus Greene, (ft) The fruiting 

 carpels are sometimes twisted and either sterile or fertile: Ocean View, San Francisco, K. 

 Brandegee 12p, 13p, 14p, 15p. Cf. P. contortus Greene, based on a spm. from Lake Co., or 

 Colusa Co., Curran. (i) There is frequently a tendency to extreme hairiness of carpels. This 

 variation seems correlated with extreme hairiness of stems and buds, especially when young: 

 Springville, Tulare Co., Purpus 1749. On the other hand the reverse correlation is not true, 

 since Purpus 5000 (Erskin Creek, Kern Co.) has very hairy buds and stems, but glabrous 

 carpels. 



It is possible that further collections and field studies may show some of the specific segre- 

 gates, listed below as reductions, to be of varietal rank, but it is more likely that accumulation 

 of knowledge concerning the range and kind of variation will destrdy this possibility. No other 

 Californian species seems so inviting for a study of fluctuating variability, particularly in 

 intensive garden cultures^ It is probable that such work would reveal the most unexpected 

 surprises.

 e. San Diego Co., Jepson 8734. 



Var. crinitus Greene. Peduncles and buds with longer hairs, often densely pilose; buds 

 globose; petals yellow, often with pink or greenish tips Tehachapi Mts. south to the Cuya- 

 maea Mts. : Tehachapi, Greene; Coahuilla Valley, Riverside Co., Jepson 1470. This variety 

 is not definitely different from the species but merely represents a terminus of a line of 

 variation. 



Var. horridulus Jepson n. comb. Petals spreading nearly rotately from a turbinate or 

 almost cylindric base 3 to 4 lines long; carpels white when young with a dense covering of 

 stiffish hairs, the hairs rapidly deciduous and the carpels soon becoming only thinly hairy. 

 Southern Sierra Nevada foothills from Fresno Co. to Tulare Co., 3500 to 5000 ft.: ridge n. 

 of Pinehurst, Fresno Co., Otiley 1438, Newlon 202 ; e. of Springville, Tnlare Co., Purpus 1749. 

 The following spms. have carpels destitute of the heavy coat of hairs just described, being in 

 pubescence similar to the ordinary form of Platystemon californicus, but they have turbinate 

 corollas in various degrees or intergrades: Pleasant Canon, Panamint Mts., Hall $ Chandler 

 6958; Erskine Creek, Kern Co., Purpus 5000; Leonis Valley, betw. Manzana and Gorman, 

 Davy 2659. These facts evidence that the corolla character is more constant than the 

 pubescence character, although the latter is the more striking. In those plants (as first cited 

 above) where both characters are found intensified we have a state which is really an extreme 

 in a series of variations. 



Var. nutans Brandegee. Fruits nodding. Coast of Southern California; San Diego, T. 

 Brandegee; Santa Cruz IsL, T. Brandegee.
