Var. lindleyi Jepson. Si'otted Blush. Petals 10 to 17y2 lines long, almost uniformly with 

 a large central blotch. — Mostly along the coast, 100 to 2500 feet, from Sonoma Co. to Del Norte 

 Co. North to Washington. June-July. In Sonoma Co. the spot on the petals is inside; towards 

 the interior of Humboldt Co. we find it on the outside (Redwood House, M. S. Baker 68), but on 

 the inside along the coast line (Capetown, Jepson). In other localities colonies show both spotted 

 and unspotted petals. The capsules are thickened at the middle in Sonoma Co., but this char- 

 acter occasionally appears in northern plants also. Indeed, there is a fluctuating tendency for 

 the capsule to Ihicken at the middle or above in all of our species. 



Locs.— Windsor, Sonoma Co., Jepson 9206; Willits, Jepson 12,357; Ft. Bragg, W. C. 

 Maiheu-s; Bear Hiver, Humboldt Co., Jepson 2141; Shelter Cove, Humboldt Co., Tracy 4998; 

 laqua, Humboldt Co., Tracy 7739; betw. Three Creeks and Eedwood Creek, Humboldt Co., Jepson 

 2130; Ragged Hill, Crescent City, Jepson 9406. Other similar large-flowered specimens without 

 the characteristic petal blotch range southward to San Mateo Co.: Moss Beach, Alice King; 

 betw. Salada and Mussel Rock, Ncwlon 251. 



Var. concolor Jepson. Simple or with a few branches from the base, 8 to 12 (or 24) inches 

 high; leaf-blades narrowly linear to lanceolate; buds sometimes nodding; petals uniform crim- 

 son, 5 to 71/^ lines long; capsule slender, minutely canescent, tipped with a beak 1 to 2i/^ lines 

 long. — Hillslopes and flats, 1900 to 5200 feet: North Coast Ranges from Napa Co. to Trinity 

 Co. ; Sierra Nevada from Eldorado Co. to Modoc Co. May-July. This variety is closely similar 

 to G. arcuata Jepson in foliage, flowers and fruit and seems to differ only in pubescence of capsule.
