LINACEJ^. 



GENERA. 



I. LINE^. 



1. Linum L. — Flowers hermaphrodite regular, 4, 5-merous ; 

 receptacle convex. Sepals entire or more rarely o-dentate, imbri- 

 cate. Petals often cohering at margin, contorted, fugacious, some- 

 times ligulate. Stamens double in number to the petals, 2-seriate ; 

 the oppositipetalous sterile, dentiform or setiform ; all the filaments 

 connate at base in a short tube ; anthers introrse, 2-rimose. 

 Glands 4, 5, alternipetalous, adnate to outside of staminal tube 

 more or less prominent, equal or more rarely imequal. Germen 

 free; cells 3-5, oppositipetalous, by spurious dorsal dissepiments 

 more or less deeply 2-locellate ; style terminal, afterwards 3-5- 

 partite, branches stigmatiferous at apex, linear or variously dilated 

 or capitate. Ovules in cells 2, collaterally descendent; micropyle 

 extrorse superior, blocked by thick obturator. Capsule septicidal 

 3-5-valved ; cells imperfecly septate, 2-spermous ; or sub-com- 

 pletely divided by septa 6-10-coccate; cocci 1-spermous. Seed 

 descendent ; albumen scanty, oily ; embryo straight, fleshy ; radicle 

 superior. — Herbs, undershrubs or shrubs, usually glabrous ; leaves 

 alternate or more rarely opposite, entire or serrate ; stipules small, 

 caducous, sometimes glanduliform or ; flowers disposed in terminal 

 or axillary cymes, often corymbiform or raccmiform, rarely 2-choto- 

 raous 2-parous, usually laterally 1-parous. {All temperate and 

 extra-tropical warm. reg. and tropical-mount?}. See p. 42. 



2. Anisadenia Wall. — Flowers nearly of Linum., 5-merous, 

 exterior sepals 2, 3, dorsal 1, 2-seriate glandular-setiferous. Glands 

 adnate to exterior of staminal tube, 3-6, unequal ; one often 

 larger. Germen 3-loeular ; cells 2-ovulate. Other characters of 

 Linus. Capsule oblong, membranous (indéhiscent?), usually 1-
