'"). V. Howellii. Glabrous throughout, short caulescent, 2 

 or vj inches high: leaves I or 2, thickish, about 1 1/^ inches long, 

 with ovate outline, pinnatifid, the oblong segments irregularly cus- 

 jjidate-toothcd and lobed, with revolute margins: umbel 8 to 0- 

 ra} ed (sometimes with 1 or 2 sessile umbellets), with no involucre, 

 and involucels exceedingly prominent, being exactly like the 

 leaves and forming the principal part of the foliage of the plant; 

 rays fi to 8 lines long; pedicels about a line long: calyx-teeth 

 prominent: fruit (immature) oblong, glabrous, a line long: oil- 

 tubes several in the intervals,

Tliis interesting alpine Vehia closely resembles 1'. Parish iiC k 11. 

 in foliage. Its dwarf liabit and remarkable involucels well characterize it. 



<*>. V. vestita. Acaulescent, 2 to 4 inches high, densely 

 clothed throughout with white soft spreading hairs: leaves pin- 

 nately compound, with numerous crowded confluent oblong seg- 

 ments: umbel 10 to Lj-rayed, with no involucre, and involucels of 

 numerous lanceolate bractlets; n;ys 4 to <S lines long; fruit 

 sessile or nearly so, the sterile pedicels i\ to i) lines long: fruit 

 ovate-oblong, pubescent, 2 to %]4 lines long, \% lines broad, with 

 inconspicuous ribs: oil-tubes 8 to 4 in the intervals, 8 on the com- 

 missural side. (Fig. \Jt().)~Dcu'cya vcstiia Watson, Proc. Am.

 elongated roots, with radical pinnate leaves, no involucre, involu- 

 cels of few small bractlets, and yellow flowers. — IJased upon

The fact that this can be made an outlying member of several genera 

 and a satisfactory member of none suggests the propriety of i-solating it 

 and thus making more consistent generic groupings. It bi-ings trouble into 

 every genus undei- which it can be placed, and thus seems to prove its 

 right to generic independence. First placed under 7't/«6c/'./a by Gray, it 

 differs from that genus ciiieHy in its numerous small oil-tubes, instead of 

 solitary large ones, and ir^ not having an involute seed-face, deferred to 

 Eulophiis by Benthani & Hooker, its deeply and narrowly sulcate seed^ 

 face at once contradicts the broad and shallow sulcus of that genus, to say
