SAKRACENIACE^E 119 



The seed itself is oval in outline, and the funicle terete or cylin- 

 drical. The embryo is also cylindrical and nearly as long as 

 the endosperm. The cotyledons are plano-convex, and many 

 times shorter than the radicle. 



Seedling. After germination the cotyledons increase greatly 

 in length proportionately to their width. The hypocotyl is 

 terete, slender, of considerable length, surmounted by the 

 linear, acute, slender, one-nerved cotyledons, which are dilated 

 and connate at the base, forming a little cup surrounding the 

 plumule. 



The first leaf of Darlingtonia californica ' is narrowly linear, 

 acute, and resembles the cotyledons ; but is smaller and shorter. 

 The second and third leaves are clavate, tubular, sheathing at 

 the base, and ending in subulate, hooked, or incurved points. 



The adult leaves vary from 12 to 18 inches in length, and 

 are all radical, with the petiole tubular, twisted half round on 

 its axis, furnished with a narrow wing on one side, on the edge 

 of which are glands, vaulted, saccate, and recurved at the apex 

 with the orbicular mouth on the lower side of the hood and 

 facing downwards, striate longitudinally with parallel nerves 

 and smaller ones between them ; lamina at the lower and outer 

 edge of the hood, narrowed at the base, with two oblong 

 or lanceolate widely diverging lobes of some considerable 

 length. The interior of the pitcher is furnished with hairs 

 pointing downwards; near the upper end they are short 

 and conical, those below are longer. They are of a glandular 

 nature and serve to decompose insects, which are caught in 

 large numbers.

Fruit and Seed. In this Order the carpels are generally 

 connate into an ovoid or oblong one-celled ovary eventually 

 forming a capsule or pod ; they are however distinct in Platy- 

 stemon, and form a two-celled ovary in Glaucium ; the ovules are 

 anatropous, ascending or horizontal ; the micropyle is inferior ;
