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 6 — 8, broadly ovate, scarious-margined, % — 

 % in. long: petals 12 — 15, oblong, J£ — 1 in. long, pinkish or white: sta- 

 mens 40 or more: capsule broadly ovate, J£ in. long. — On Ml Diablo, 

 Mt. Hamilton, etc. 



3. CALANDRINlA, II. 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. Rather slender, diffuse, the 

 branches 3 — 6 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 3 — 10; seeds 

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



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

 i_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 10 — 15: 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. April — 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 (J£ in. long) capsule: seeds dull, tuberculate. 

 — Mt. Tamalpais. 



4. CLAYTOJilA, Qronovius. 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 shiningseeds. 



* Perennial; pedicels axillary to a bract. 



1. C. Sibirica, L. Stems 1 — 1J^ 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,
