crown, with bifid lobes alternate with the oblong versatile anthers. 
Capsule sessile, subglobose-triquetrous. Seeds large. 
+ + Perianth salver-form ; segments 3-nerved : pedicels not jointed. 
9. Mitxa. Flowers white, greenish outside with stout green midveins, 
the tube narrowly turbinate. Stamens nearly sessile, in one row, 
naked: anthers basifixed. Capsule sessile, oblong-obovate. 
TrrpeE III. Leucocrinez. Acaulescent; flowers on subterranean pedicels 
in a sessile umbel, with elongated linear bracts, from a short rootstock : peri- 
anth salver-form, with linear tube and several-nerved segments: stamens in 
one row near the throat; anthers basifixed: capsule sessile, triangular-obovate ; 
seeds obovate, angled, several in each cell. 
10. Levucocrinum. Flowers white, very fragrant. Filaments fili 
form; anthers linear. Style slender and elongated, tubular, 
dilated at the summit. Leaves narrowly linear, surrounded at 
base by scarious bracts. Floral bracts sheathing the pedicels. 
Sussertes II. Inflorescence racemose or paniculate. 
TrinE IV. Phalangieze. Flowers mostly small, with distinct segments, on 
jointed naked pedicels with small bracts, in simple or usually paniculate racemes : 
stem somewhat leafy or naked, from a tunicated bulb or rootstock or fleshy- 
fibrous root: anthers versatile. 
* Capsule obovate or oblong: seeds angled, several in each cell: flowers 
rather large, racemose on a naked scape from a tunicated bulb. 
11. Camassta. Flowers blue (rarely white), slightly gibbous; seg- 
ments 3—7-nerved, spreading. Base of the style persistent. 
Seeds black and shining. Raceme open. Leaves linear, flat. 
* * Capsule oblong; cells several-seeded: seeds angular and somewhat flat- 
tened: pedicels (usually fascicled) jointed near the middle : root fleshy-fibrous. 
12. HesPeERANTHES. Flowers yellow or yellowish ; segments spread- 
ing from the base, 3—5-nerved in the middle, twice longer than the 
stamens, at length twisted over the ovary. Filaments muricate, 
longer than the anthers. Style elongated and very slender, 
becoming declinate. Leaves narrowly linear and grass-like, sur- 
rounded at base by the fibrous remnants of older ones. — Anthe-

* * * Capsule triangular-obovate, 3-lobed ; cells (2-ovuled) 1-2-seeded : seeds 
obovate: pedicels (mostly solitary) jointed at the summit: stem from a tuni- 
cated bulb or rootstock. — Subtribe CHLOROGALEX. 
13. ScH@NoLiRION. Flowers yellow or whitish, in loose simple or 
sparingly panicled racemes, the perianth not scarious nor becom-
