Polemonium delicatum sp. nov. 



A small glandular perennial with slender horizontal rootstock. 

 Stem very slender, about i dm. high : leaves 3-8 cm. long ; leaf- 

 lets 5-1 1 pairs, very thin, ovate, ovate-lanceolate or oblong, 

 mostly acute, 3—10 mm. long: inflorescence usually branched; 

 branches 3— 4-flowered ; pedicels slender, 5—15 mm. long; calyx 

 glandular, 4—5 mm. long: lobes lanceolate, acute: corolla blue, 

 open-campanulate, about 7 mm. high and 8 mm. broad : stamens 

 about equalling the corolla. 



This is nearest related to P. parvifloruui Nutt., but is still 

 smaller and characterized by its slender pedicels, small flowers and 

 acute calyx-lobes. It grows at an altitude of over 3000 m.

Polemonium speciosum sp. nov. 



A low viscid-villous plant, cespitose with a perennial rootstock. 

 Stem 1—2 dm. high with 2—3 leaves : basal leaves numerous, 8—15 

 cm. long with wing-margined rachis ; leaflets opposite, 7-9 pairs, 

 ovate, 6—12 mm. long, acute: stem-leaves similar but smaller : in- 

 florescence capitate : calyx viscid-villous, 15—20 mm. long, cleft to 

 about the middle : lobes lanceolate, acute : corolla pale blue, deeply 

 campanulate-funnelform, 2—2.5 cm. long: limb about 1.5 cm. 

 broad. 



The form of the corolla, the dense capitate inflorescence and 

 the viscid pubescence place this species nearest P. viscosinn, and 

 P. comfcrtimi, but the leaflets are not verticillate, the corolla is 

 larger than that of the former and broader than in the latter.

Gilia Candida sp. nov. 



A glandular perennial with short caudex. Stems often more 

 than one, ascending or erect, simple, 4-6 dm. high, leafy : leaves 

 rather fleshy, divided into linear-filiform, .spinulose-tipped seg- 

 ments ; the upper gradually smaller: inflorescence a very narrow 

 panicle : branches usually very short and few-flowered : flowers 

 subsessile : calyx glandular-pubescent, about 8 mm. long ; its lobes 

 lanceolate, bristle-tipped : corolla white, or rarely pale pink, 2—3
