260 PLUMB AGINE^. [Statice. 



Salt marshes, Norfolk, Suffolk, Cambridge ; fl. July- Aug. — Glabrous, except 

 the scaberulous panicle. Eootstock much branched. Leaves |-1| in., few, 

 obtuse. Scape 4-8 in., rather slender, excessively branched; branches 

 spreading, recurved ; spikelets unilateral, usually fascicled at the ends of 

 the branchlets ; bracts with broad scarious margins, inner ^ longer than the 

 intermediate; flowers much smaller than in S. Limo'nium, £ in., pale lilac. 

 ■ — Distrib. Atlantic, Mediterr., and Black Seas, E. Asia. — The commonest 

 Mediterranean species, I doubt not the Limo'nium reticula'tum of Kay, and if 

 so it is the S. reticulata of Linnaeus, founded on a Maltese plant. 



Order XLVI. primula'ce^e. 



Perennial, rarely annual herbs. Leaves radical or cauline, exstipulate. 

 Flowers 2-sexual, regular. Calyx inferior, superior in Samohis, 5- (rarely 

 4-9-) cleft. Corolla usually hypogynous (0 in Glaux), rotate bell- or 

 funnel-shaped, 5- (rarely 4-9-) cleft. Stamens inserted in the corolla-tube 

 opposite its lobes, with sometimes alternating staminodes (hypogynous in 

 Glaux), filaments usually short ; anthers bursting inwards by slits, rarely 

 by terminal pores. Ovary 1-celled ; style simple, stigma undivided ; 

 ovules many, amphitropous rarely anatropous, placenta free-central. 

 Capsule 1-celled, dehiscing by simple or 2-fid valves or transversely. 

 Seeds sunk in cavities of the placenta, testa thin, hilum usually ventral, 

 albumen fleshy or horny ; embryo terete parallel to the hilum. — Distrib. 

 N. temp., Arctic and mountain regions, Chili and Fuegia ; genera 21 ; 

 species about 250. — Affinities. With Myrsincas and Plumbaginece. — 

 Properties unimportant.
