12a. Lappula heterpspenna homosperma A. Nels. Bot. Gaz. 34: 29. 1902. 

 Larger than the species, paniculately and somewhat rigidly branched from 

 near the base upward: nutlets all similar and with the character of the cupu- 

 late ones of the species. Northern Colorado. 



4. PECTOCARYA DC. 



Small annuals with narrow subopposite leaves and minute flowers. Calyx 

 cleft to the base or nearly so and open in fruit. Corolla with crests nearly 

 closing its throat, the 5 short stamens included. Style minute with capitate

 strigose, branched from the base, the several stems filiform, spreading, 5-20 

 cm. long: leaves linear, imperfectly opposite, mostly less than 1 cm. long; 

 the floral one of the pair reduced or wanting: flowers single at the nodes: 

 nutlets geminate, very flat, irregularly and narrowly winged at the sides, sides 

 and apex bordered with hooked bristles, the dorsal disk slightly keeled and 

 glandular-hairy. Known only fro'm type locality, Point of Rocks, Wyoming. 



6. ERITRICHIUM Schrad. 



Dwarf, caespitose, mountain perennials with narrow leaves and small white 

 or blue flowers. Corolla rotate, with short tube, 5 crests in the throat, and 

 5 included stamens. Nutlets divergent, with sharp margin or winged by an 

 acute pectinate-toothed border. Omphalodes. 



Pubescence long and yillous . . . . . . . .I.E. argenteum. 



Pubescence short, sericeous- canescent . . . . . . . 2. E. Howardii. 



1. Eritrichium argenteum Wight, Bull. Torr. Bot. Club 29: 411. 1902. 

 Densely caespitose, only 2-4 cm. high, closely villous with long soft white 

 hairs: leaves narrowly ovate to narrowly lanceolate: flowers terminating 

 very short leafy shoots, becoming more or less racemose: nutlets with a 

 pectinate-toothed or spinulose dorsal border. Omphalodes nana aretiodes. 

 Alpine; in Colorado, Utah, Wyoming, and northwestward. 



2. Eritrichium Howardii (Gray) Rydb. Mem. N. Y. Bot. Card. 1: 327. 

 1900 v . Densely caespitose, sericeous-canescent with appressed pubescence: 

 leaves spatulate-linear, 7-15 mm. long, crowded on the tufted branches of the 

 caudex: stems short, with a few linear leaves, simple or dichotomous, few- 

 flowered: corolla larger (7-10 mm. broad): nutlets flattened dorsally, the disk 

 smooth or minutely papillose, the margin acutely angled. Omphalodes 

 Howardii. (Eritrichium elongatum Wight, Bull. Torr. Bot. Club 29: 408. 1902). 

 Wyoming, Montana, and westward in the mountains. 



6. ALLOCARYA Greene 



Small semisucculent somewhat hirsute annuals, with opposite (at least the 

 lower) linear leaves, and several to many slender usually depressed branches 

 from the base. Flowers, small, white, racemose, on turbinate-thickened pedicels. 

 Calyx 5-parted. Corolla salverform, yellow-throated. Nutlets 4, variable

Pruit ing racemes dense 2. A. Nelsonii. 



1. Allocarya scopulorum Greene, Pitt. 1: 16. 1887. Minutely strigillose- 

 bispid or the leaves glabrate above, branched from the base; the slender, 

 prostrate-spreading stems at length branched, 7-15 cm. long: leaves linear, 

 the floral somewhat elongated: calyx-segments not accrescent, linoar-lanceolatr: 

 nutlets with ovate nearly basal scar, slightly carinate ventrally and also
