is membranous at summit, and its oblong or elliptic short green 

 teeth are seemingly not a continuation of the tube, but are 

 inserted below the margin, on the outside, and often scarcely 

 exceeding its membranous rim. Unless these characters are dis- 

 tinguishing, it will have to take varietal rank. 



Gentiana strictiflora ( Ry db. ) . — ^ G. acttta strictiflora Ry db. 

 Mem. N. Y, Bot. Gard. i : 309. 1900 ; full citation given in the 

 same place, — This well deserves specific rank. It has quite as 

 good characters as the allied species G. acuta, G. tcnella^ and 

 G. heterosepala. Its large size, strict habit, numerous flowers, 

 and the distinctly ochroleucous corollas are wholly characteristic. 

 Common in moist swales on bottom lands. 



Gentiana calycosa xantha, n. var. — Habit of the species, 

 smaller, \^^ or less high : leaves about five pairs, longer than 

 the internodes ; the single flower smaller, yellow or yellowish- 

 white with numerous green dots. 



At first sight theseplants strike one as a decided novelty, but closer exam-

 green dots in the corolla are not wanting in the species itself, though much 

 obscured by the deep blue of that.

Phacelia corrugata, n, sp. — Biennial or more enduring, 3-5 "^"^ 

 high, slightly glutinous and more glandular-pubescent : stem 

 either branched or simple at base, the branches also sparingly 

 branched, moderately leafy, terminating in elongated naked 

 peduncles : leaves narrou^ly oblong in outline, somewhat alter- 

 nately ii-i5-lobed,the broad sinuses extending about halfway to 

 the midrib, each lobe with two to four rounded unequal lobules ; 

 petioles short or wanting : spikes very dense even in fruit, rather 

 tardily open ; pedicels very short (i"""): sepals linear-oblanceo- 

 late, sparsely hirsute, nearly as long as the corolla : corolla blue, 

 campanulate-funnelform, 1*=°^ or more long, as much in diameter 

 over the limb, lobes suborbicular, internal folds short and united 

 around the base of the filament : stamens and styles nearly twice 

 the length of the corolla ; the undivided base of the style pubes- 

 cent : capsule elliptical, about 5 """^ long: the seed oblong,
