MANAGEMENT CONSIDERATIONS: Eriogonum caespitosum is a very low 

 plant with most of its foliage very close to the ground. It is 

 probably not used by livestock, although trampling could be 

 detrimental to the plants. Current management practices are 

 probably not detrimental to the populations of this plant. 



Halimolobos virgata (Nutt.) Schulz 



Twiggy halimolobos 



DESCRIPTION: Twiggy halimolobos is a short-lived perennial with 

 1-few, simple or branched stems, 10-35 cm (4-14 in) high, arising 

 from a taproot and rootcrown. Spatula-shaped leaves, 2-6 cm (1-2 

 in) long, with broadly serrated margins are clustered at the base 

 and scattered on the stem, becoming smaller upward. The 

 uppermost leaves clasp the stem at the base. Foliage is covered 

 with a mixture of simple and branched hairs. Flowers on 

 ascending stalks are arranged in a narrow, open inflorescence at 

 the top of the stem. Each flower has 4 separate sepals, 2-3 mm 

 long; 4 separate, white petals, 3-4 mm long, with purplish veins; 

 and 4 long and 2 short stamens. The glabrous linear capsules 

 (siliques) , 2-4 cm (ca. 1 in) long, are borne on arching- 

 ascending, hairy stalks up to 12 mm long. 



This nondescript plant is similar to many species of Arabis. It 

 may be distinguished by the combination of petals less than 4 mm 

 long, branched pubescence, and siliques that are nearly round in 

 cross-section rather than flattened. H. perplexa does not have 

 clasping stem leaves. A hand lens or microscope and technical 

 key are essential for determ.ination.
