1. S. Limonium, T.inn. Rootstock thick, very astringent: leaves obuvate- 

 ohlong, tlucki-sli, Ikbhy curiaceous, pale, tapering into a petiole : scape a I'uot ov two 

 high,°mucli-branclieil, cuiymbt)se-panicled, bearing the numerous 2 - 3-llo\vcrea 

 spTkeiets on one sitle of its divisions : outer bract ovate, herbaceous on the back, 

 much smaller tiian the broadly scarious innermost bract: calyx-tube more or less 

 hairy on the angles. 



Salt marshes on the coast ; the var. Califounica (i\ Califomica, Boiss. in DC), with denser 

 and more coiymbose iullorescence than the Atlantic coast plant (var. Caroliniaiia), but closely 

 resembling the H. Livionium of Europe. 



OuDEii LVn. PRIMULACE^. 



Herbs, Avith perfect legular llowers, well marked by having the Btamcns as many 

 as the lobes of the corolla and opposite them, inserted on its tube (only in Glaux 

 the corolla is wanting and the stamens on the calyx alternate with its lobes), a 

 single entire style and stigma, a one-celled ovary, with the ovules borne on a free 

 central placenta, and a capsular fruit. Calyx 4-8-cleft, commonly 5-clcft, hypogy- 

 nous, except in Samolus. Anthers 2-celled, opening lengthwise. Ovules several or 

 numerous, on a globular central placenta, — amphitropous (except in Ilottoula, which 

 we have not). Embryo small, in ileshy or horny albumen. — Leaves simple, mainly 

 entire : stipules none. 



An order of about 20 genera and twelve times that number of species, widely distributed over 

 the world, but mainly in the temperate and frijrid portions of the northern hemisphere, of no 

 marked active properties and small economical importance, except to the florist ; not largely 

 American, and very scanty in California, where only Dodccalheon is conspicuous. 

 ♦ No sterile filaments : calyx wholly free from the ovary. 



+- Flowers umbellate or sometimes solitary, on a naked scape : corolla imbricated in the bud. 



1. Dodecatheon. Corolla 5-purted ; its divisions rclloxod. Shimens projecting ; lilamcnls 



nionadclpliouH, shorter than the connivont saj^attulo or lanceolate anthers. 



2. Primula. Corolla salverform, or funnelform with a Hat limb, the tube rather long. An- 



tliers obtuse, included. „.,.,.,, i- *u 



3. Androsace. C"orolla short-salverform or funnelform, small, with tube hardly exceeding the 



limb. Antliers obtuse, included. 

 +- +- Flowers axillary on leafy stems : corolla convolute in the bud, or none in No. 7. 



4. Trientnlis. Corolla 7- (iVO-) I'arlcd rotate. Capsule opening lengthwise. 



5. Anagallia. Corolla n-imrlcd, hmgcr than tlio calyx, rotate. Capsule ciicumscissile. 

 (5. Centunculus. Corolla •! -5-clelt, shorter than the caly.x. Capsule cucumscissilo. 



7. Glaux. Corolla none. Calyx colored. Capsule opening at the top by valves. 



* Sterile filaments alternate with the lobes of the corolla : calyx-tube partly adnate. 



8. Samolus. Corolla caiapanulato, 5-clcft ; the lobes imbricated in the bud. Flowers 



racemose. 

 Lysimacmia. It is remarkable that no species of this rather large genus is known in 

 California. But L. ciliata occurs in Oregon, and may reach the northern part of the btate. 

 It belongs to a section (Sh-ironnma) which has the lobes of the corolla uivolute severally around 

 the stamens. The genus is most like Trlcnlalis, but the parts of the llowcr live, and the stems 

 eipiably leafy throughout. 



1. DODECATHEON, Linn. 



Calyx deeply 5-cleft, the divisions rellexed in ilower, afterwards erect over the 

 capsule. Corolla with extremely short tube, a dilated and thickened throat, and 

 an abruptly rellexed 5-i)arted limb ; its divisions long and narrow, entire. Stamens 

 inserted on the throat of the corolla : lilaments .short, monadelphous (but separable
