acutish: peduucles scapiform, very slender: fl. %--l in. broad: petals 

 as in the last : stamens oo ; filaments filiform or flattened : capsule ovate- 

 triquetrous, % "1- lo^& or more. — Less common than the preceding, 

 preferring gravelly hills toward the sea, or bluffs of rivers in the interior; 

 the larger forms showing the ligulate-dilated filaments of n. 1, from 

 which species only the acaulescent habit and the strictly capsular fruit 

 separate it. Mar.— May. 

 * * * Carpels 3 only, united, fowling a slender elongated and twisted 

 1-celled capsule; stamens few and dejinile; stigmas linear. — 

 Genus Meconella, Nutt. 



3. P. Torreyi. Mecuuella Californiea, Torr.; Frem. 2d Rep. 312 

 (1845). Platysligwa Californicnm„Bo\and. Oat. 4 (1870). Erect, slender, 

 dichotomous from the base, 3 — 8 in. high, glabrous: lowest leaves ovate- 

 spatulate or oblanceolate; upper linear, acute, entire, ^^ — 1 in. long: fl. 

 % — 1 in. broad, white: stamens (usually 12) in 2 circles; filaments 

 dilated upwards, those of the outer circle conspicuously shorter than 

 those of the inner: capsule narrowly linear, %~'^% in. long. — The plant 

 of the Sierra foothills (Mokelumue Hill, Bigeloir; Rose Springs, Mrs. 

 Gates) is much more slender than that of the San Francisco region, and 

 has flowers only half as large. This, however, can not be referred to the 

 Oregonian type of Meconella, for that has but a single set of stamens. 

 In our i)lant, whether of the Sierra or of the Coast Range, these, though 

 sometimes only 8 or 10, are always in two sets, the outer circle with short, 

 the inner with long filaments. — Mar. — May. 



4. P. deiiticulatus, Greene; Bull. Calif. Acad. ii. 59 (1886), under 

 Meconella; Bull. Torr. Club, xiii. 218, under Platysligwa. More slender, 

 3 — 10 in. high, simple below, ternately branching above the middle: 

 lowest leaves in a depressed whorl, the rhombic-ovate acute blade shorter 

 than the linear petiolar basal part; cauline in whorls of 3 or more, 

 spatulate or linear, obtuse, remotely and saliently dentate : corolla }^ — J^ 

 in. long: stamens 6 — 9, in one set and all equal; filaments flattened, but 

 broader below. — A very distinct species, common southward beyond our 

 limits, but reaching Monterey Co., Hickman. At the time of its publi- 

 cation, Dr. Gray wrote that he had been about to publish it as Flatystigma 

 Clevelandi. Mar., Apr. 



4. DEXDROMECON, Bentham. Shrubs with alternate coriaceous 

 entire leaves, and solitary rather large yellow flowers. Sepals 2. Petals 4. 

 Stamens go; filaments filiform, short: anthers linear. Ovai'y linear; style 

 short; stigmas 2, short and erect. Capsule linear, many-nerved, 1-celled, 

 2-valved, the valves dehiscent somewhat elastically from base to apex. 

 Seeds go , oblong or globose, " finely pitted " (smooth in the extra-limital 

 insular species, D. JtexileJ.
