1. L. rediviva, Pursh. Leaves densely clustered on the short thick 

 caudex, linear-oblong, glabrous, glaucous: scapes little exceeding the 

 leaves, jointed at the middle, and with 5 7 subulate scarious bracts 

 whorled at the joint : sepals 68, broadly ovate, scarious-margined, Y 2 

 % in. long: petals 1215, oblong, ^1 in. long, pinkish or white: sta- 

 mens 40 or more : capsule broadly ovate, 3^ in- long. On Mt. Diablo, 

 Mt. Hamilton, etc. 



3. CALANDRIXIA, H. B. K. Sepals 2 only, subequal, persistent. 

 Petals 3 10. Stamens 3 25, apparently always hypogynous. Capsule 

 3-valved from the summit. Seeds several. 



1. C. Menziesii (Hook), Torr. & Gray. Kather slender, diffuse, the 

 branches 36 in. long: leaves linear-spatulate, mostly radical and long- 

 peduncled; the upper and floral reduced and glandular-ciliate: sepals 

 ovate, acuminate, the margins and sharp keel glandular-ciliate: corolla 

 little exceeding. the sepals, white or bright purple: stamens 310; seeds 

 broadly ovoid, shining. Coast Range. April, May. 



2. C. elegans, Spach. Larger and stouter than the last, glabrous, 

 the decumbent and ascending branches often 1 ft. long, flowering 

 throughout: sepals ovate, acute or acuminate, less sharply carinate, the 

 keel and margins entire or with a sparse short and flattened but in no 

 wise glandular ciliation: stamens 1015: corolla twice the length of the 

 calyx, % in. broad when expanded, bright rose-red: seeds larger, nearly 

 orbicular. Very common throughout the Bay region and elsewhere in 

 the State. Apjil June. 



3. C. Breweri, Wats. Habit of the preceding but still larger, the 

 ascending branches often more than 1 ft. high, glabrous: pedicels rather 

 remote, in fruit deflexed: sepals broadly ovate, truncate at base, sur- 

 passed by the long-conical (^ in. long) capsule : seeds dull, tuberculate. 

 Mt. Tamalpais. 



4. CLAYTOMA, Gronovius. Glabrous herbs, often glaucous. 

 Leaves radical except an involucral pair (sometimes united) under the 

 racemose or subumbellate inflorescence of the usually scapiform pedun- 

 cles. Sepals 2, persistent. Petals 5, equal, commonly united by their 

 short claws. Stamens 5, each joined to the claw of its petal. Capsule 

 membranaceous, ovate or globose, 3 valved, elastically dehiscent, each 

 valve elastically involute, ejecting the rather few black and shining seeds. 



* Perennial; pedicels axillary to a bract. 



1. C. Sibirica, L. Stems 1 1^ ft. high: herbage almost dark green, 

 disposed to blacken in drying: radical leaves lanceolate to rhombic - 

 ovate, acute or acuminate, 1 2 in. long, long-petioled; cauline sessile,
