FLOWERING PLANTS AND FERNS OF ARIZONA 805 



flowers axillary, mostly in whorls, the lower flowers often solitary; 

 corolla small, blue and white, deeply 2-lipped; filaments glabrous; 

 capsule few-seeded. 



1. Collinsia parviflora Dougl. ex Lindl., Edwards's Bot. Keg. 13: 

 pi. 1082. 1827. 



Gila and Yavapai Counties, 4,000 to 6,000 feet, moist soil along 

 streams, February to May. Canada to New Mexico, Arizona, and 

 California. 



Miss Newsom doubtfully refers to this species a collection in the 

 Chiricahua Mountains, Cochise County (Lemmon 3073) in which " the 

 corolla-throat is open, the upper lip not at all reflexed, the tube slender 

 and not gibbous, and the plant quite conspicuously glandular." 



7. SCROPHULARIA. Figwort 



Coarse perennial herbs; stems tall, erect or nearly so, leafy; leaves 

 opposite, petioled, the blades ovate to lanceolate, serrate or laciniate; 

 flowers numerous, small, in ample loose terminal panicles; corolla 

 greenish or dull red, short and broad, short-lobed; capsule 2-vaived; 

 seeds many. 



Key to the species 



1. Leaf blades (at least the lower ones) prevailingly triangular-ovate and cordate 

 at base, coarsely and irregularly, often doubly, dentate or laciniate. 



1. S. CALIFORNICA. 



1. Leaf blades prevailingly lanceolate to ovate-lanceolate, mostly truncate, 

 cuneate, or subcordate at base, usually more evenly and shallowly serrate- 

 dentate or crenate 2. S. parviflora. 



1. Scrophularia californica Cham., Linnaea 2: 585. 1827. 



Pinal Mountains, Gila County, about 4,000 feet (Harrison 2090), 

 June. Central Arizona, Oregon, and California. 



Although from far outside the main area of this species, the speci- 

 men cited closely resembles many from California and Oregon. 



2. Scrophularia parviflora Woot. and Standi., Contrib. U. S. Natl. 



Herbarium 16: 173. 1913. 



Scrophularia glabrata Davidson, South. Calif. Acad. Sci. Bui. 1: 



26. 1902. Not of Aiton, 1789. 

 Scrophularia davidsonii Pennell, Notul. Nat. Acad. Nat. Sci. 



Phila. 43: 8. 1940. 



Southern Coconino County and Hualpai Mountain (Mohave Coun- 

 ty), to Cochise and Pima Counties, 5,000 to 8,000 feet, common in 

 rich soil in coniferous forests, July to October, type of S. glabrata from 

 Metcalf, Greenlee County (Davidson in 1902). Western New Mexico 

 and Arizona. 



The stems reach a height of 1.2 m. (4 feet) or more. This species 

 apparently intergrades, in Arizona, with S. californica Cham., which 

 it resembles in its relatively lax inflorescence, but is more like S. 

 lanceolata Pursh in the shape of the leaves. The type of $. glabrata, 

 as compared with the type of S. parviflora, has the herbage more finely 

 puberulent, the leaves thinner and more coarsely toothed, and tin 4 

 flowers smaller (barely 5 mm. long).
