SARRACENIA, Tourn. 



Rootstock short, horizontal ; scape naked. Leaves trumpet- 

 shaped, with a wing extending nearly to the base and a broad 

 blade at the apex (see Part II, Ch. XXVI) ; tube hairy 

 within, with downward-pointing, stiff hairs. Calyx 3-bracted. 

 Petals obovate, 'drooping or incurved. Style umbrella-shaped, 

 5-angled ; stigmas at the hooked angles of the style on the 

 under surface. Capsule globose, rough. [The tubular leaves 

 usually contain more or less water and dead insects, the latter 

 having been attracted by a honey-like secretion near the 

 opening. For a full account of the structure and peculiar 

 action of the leaves, see Goodale's Physiological Botany, 

 pp. 347-353.]* 



1. S. purpurea, L. SIDE-SADDLE FLOWER. Leaves ascending, 

 curved, broadly winged, purple-veined, 4-8 in. long; blade erect,

 deep purple, about 2 in. broad. Style yellowish. Mossy swamps.* 



43. SAXIFRAGACE^E. SAXIFRAGE FAMILY. 



Herbs or shrubs. Leaves alternate or opposite, generally 

 without stipules. Sepals 4 or 5, more or less coherent with

 sepals and alternate with them. Stamens as many as the 

 petals and alternate with them, or 2-10 times as many. 

 Ovary usually of 2 carpels, united only at the base or more 

 or less throughout. Fruit generally a 1-2-celled capsule, 

 sometimes a berry. Seeds many, with endosperm.
