DESCRIPTION 



1. GENERAL NONTECHNICAL DESCRIPTION: Erioqonum 

 ovalifolium var. nevadense is a perennial with a 

 thick taproot and mat-forming. The perianth is 

 narrowed directly to the attachment with the pedicel, 

 without a stipe at base, glabrous on the outer 

 surface, segments are free or nearly so; bracts at 

 base of inflorescence only wholly foliaceous, usually 

 scale-like. The inflorescence is capitate with 

 yellow flowers. 



2. TECHNICAL DESCRIPTION: Erioqonum ovalifolium var. 

 nevadense as a caespitose perennial, forming mats up 

 to 3-4 dm. broad; leaves all basal, from pannose- 

 lanate and nearly white on both surfaces to less 

 heavily tomentose and often somewhat greenish, from 

 spatulate and less than 1 cm. long to slenderly 

 petiolate, the petioles 1-3 times as long as the 

 blades, which are elliptic to rhombic, oblong, oval, 

 or oblanceolate, 5-20 mm. long, and 3-15 mm. wide; 

 flowering stems leafless, 3-20 cm. tall, tomentose; 

 inflorescence a capitate cluster of several 

 involucres, 1-3.5 cm. broad, rarely the involucres 

 short pedunculate and inflorescence somewhat 

 umbellate, subtended by 3 or more linear-lanceolate 

 bracts or very rarely with one or more of the bracts 

 foliaceous; involucres narrowly turbinate to almost 

 cylindric, 3-5 mm. long, with 5 lanceolate, erect or 

 occasionally recurved teeth 0.5-1.5 mm. long; 

 perianth glabrous externally, yellow 3-4 mm. long, 

 nonstipitate, the segments free almost to the swollen 

 base, the outer ones oblong to obovate, often 

 slightly cordate at base, considerably broader than 

 the oblong to spatulate inner segments; flowers 

 commonly imperfect, yellow; filaments pilose at base; 

 ovary glabrous. 



3. LOCAL FIELD CHARACTERS: Erioqonum ovalifolium var. 

 nevadense is distinguishable by the rounded bright 



yellow flowers. The perianth is narrow and attached 

 directly to the pedicel without a stipe at the base. 

 The leaves are basal and oval shaped. 



GEOGRAPHICAL DISTRIBUTION 



RANGE: Erioqonum ovaliforum var. nevadense is 

 widespread throughout lower elevation from 4,000-7,000 

 feet. It is usually found in sandy soils. 



:. CURRENT SITES: Erioqonum ovalifolium var. nevadense 

 is found within the sand dune region of Centennial 

 Valley, the north side of Red Rock Lakes National 

 Wildlife Refuge. In Montana it is known from many 

 sites in southern Beaverhead County.
