PLANTS INDIGENOUS TO 
[Droseracece. 
Ill .—PARIETINiE. 
Division of flower, with few exceptions, quinary. Stamens definite. Ovary soli¬ 
tary. Ovules anatropal. Placentae generally parietal. Seeds albuminous, indefinite, 
very seldom without albumen or definite. Embryo straight, erect. 
Order DEOSEEACEzE. 
Salisb. Farad. Lond. 95. 
Elowers symmetrical, hermaphrodite. Calyx persistent, divided into free sepals, 
or monopliyllous and cleft into lobes, imbricate in aestivation. Petals free, alternate 
with the sepals, hypogynous, very rarely perigyjious, persistent, imbricate in (estivation. 
Stamens free, definite in number, always singly opposite to the sepals, none or 1-3 
opposite to the petals. Anthers extrorse, terminal , two-celled, opening by longitu¬ 
dinal slits or by pores. Staminodia, if present, opposite to the petals. Styles 1 or 
3-5, simple or variously divided, sometimes obliterated. Ovules anatropal. Capsule 
2-5-valved or valveless, 1-5-celled. Arillus none. Seeds numerous, affixed to parietal 
or less frequently basal placentae, rarely 1-2 in each cell and then affixed to the 
persistent axis. Albumen copious or wanting. Embryo erect. 
Annual, perennial or rarely suffruticose plants, held deleterious, distributed 
through all zones. Stipules fringed or wanting. Leaves alternate, often irritable 
and generally furnished with gland-bearing hairs and long cilice, which are terminated 
by a deny gland, rarely glandless, very rarely quite glabrous. Peduncles terminal, 
lateral or radical, with a solitary or with racemose flowers, frequently as well as the 
leaves circmate in vernation. Petals white, red, blue, purple, or yellow, as well as the 
stamens withering and persistent.— Canid, Prodr. i. 317; JEndl. Gen, 906; IAndl, 7eg.

By this order the transit from Yiolarinese to Hypericinese is established. In 
some points of structure it approaches to Pyrolaceae, 
Tribe I. DROSEREzE, Arnott, Proclr. Flor. Ind. Or. i. 33. 
Staminodia none. Embryo at the base of a copious albumen. 
DROSERA. 
I/inne, Gen . Plant . 391.—Sundew. 
Calyx generally deeply rarely only to the middle 5-cleft, in some species 4-, 6-, 7-, or 8-cleft. 
Petals and stamens hypogynous, very seldom perigynous, equal in number to the divisions of the calyx. 
Anthers erect, longitudinally dehiscent. Styles 3-5 simple or divided. Capsule one-celled, 3-5-valved. 
Placentce parietal . Seeds numerous. Testa cellulose. Embryo minute. Radicle pointing to the hilum.
