154 MR. NUTTALL'S DESCRIPTIONS OF NEW 



POLEMONIUM. 



p. *viscosuM. Dwarf; every part covered with a short, viscid pubescence ; leaves nearly as long as the 

 short flower stems, segments rounded, ovate or subcordate, very small and short ; flowers in small 

 terminal clusters ; corolla much longer than the elongated lanceolate segments of the calyx ; ovaries 

 two or three in each cell. 



Stems thickish and rigid, somewhat csespitose. About four or five inches high, 

 the leaves on longish petioles. The leaves and calyx coA^ered with a short viscid 

 bitter pubescence, leaflets scarcely more than a line long, about the same breadth. 

 Calyx large, with lanceolate rather acute segments. 



Hab. On rocky ledges towards the sources of the Platte. Flowering in June. 

 (Nuttall.) 



GILIA. 



G. *MULTiFLoiiA. Biennial, crect and much branched from the base; stems low and pubescent; leaves 

 pinnatifid, mostly trifid, segments narrow linear and mucronulate, above simple ; flowers disposed in 

 sessile or pedicellate axillary clusters ; tube of the corolla about twice the length of the curved calyx ; 

 the segments of the corolla oblong and mucronulate ; stamens somewhat exserted. 



A biennial, about a foot high, or rather less. The leaves apparently thick and 

 slightly pubescent, the lower ones only trifid, the upper or greater number simple, 

 the primary leaves probably pinnatifid. Flowers violet blue, inclining to rose red, 

 the tube of the corolla about twice the length of the calyx, enlarging towards the 

 orifice, segments of the border oblong, spreading, minutely mucronulate. Stamens 

 exserted beyond the orifice of the tube, unequal in length, anthers round. Style long 

 and slender, with a small trifid stigma. Flowers disposed in clusters of from five to 

 ten up the greater part of the simple branches, some of the clusters sessile. Calyx 

 obconic-campanulate, membranaceous between the teeth, which are long, subulate, 

 and pungent. Capsule oval, not exserted, cells four to five-seeded. Seeds angular, 

 pale brown. Allied apparently to G. glomerijlora, but that appears to be a low shrub 

 with orange coloured flowers. 



Hab. Sandy hills along the borders of the Rio del Norte, New Mexico. 

 Flowering in August. 



G. LONGiFLORA. {Cautua longijlora, Torrey.) Found abundant in sandy places 

 along the banks of the Rio del Norte, growing beneath the shade of pine trees. 

 Flowering in August and September. A very remarkable and showy plant with 

 white flowers. Very few of the leaves are properly pinnatifid, being mostly trifid, a 

 few v^^ith two pair of segments. Tube of the corolla often as much as two inches 

 long. Leaves mostly trifid.
