Sds. 00, minute. 



An order consisting of only 2 genera, (one inhabiting the bogs of N. America, the other in Guiana,; 

 and 7 species. 



SARRACENIA. Tourn. 



In memory of Dr. Sarrazen of Quebec, the discoverer of the genus. 



Calyx of 5 sepals, with 3 small bracts at base ; petals 5, deciduous; 

 stigma very large, peltate, persistent, covering the ovary and sta- 

 mens ; capsule 5-celled, 5-valved, many-seeded. 



S. PURPUREA. Side-saddle Flower. 



Z/w.(ascidia) radical, decumbent, inflated, contracted at the mouth,winged 

 on the inner side, ending in a broad-cordate, erect lanrna. One of the most 

 curious of plants. Grows in wet meadows and about mud lakes, Lab. to Flor. 

 Leaves 6 9' long, rosulate, ever-green, composed of a hollow, pitcher-form 

 petiole (1) swelling in the middle, with a wing-like appendage extending the 

 whole length inside, from \ 1' wide, and extended on the outside of the mouth 

 into a lamina (1), covered above with reversed hairs. Their capacity when 

 of ordinary size is about a wine-glass,' and they ar generally full of water 

 with drowned insects. Scape 14 20' high, terete, smooth, supporting a single 

 large, purple, nodding flower, almost as curious in structure as the leaves. Jn.

An order consisting of 18 genera and 130 species, more than two-thirds of which are natives of Europe. 

 The order is characterized by active narcotic properties, principally resident in the turbid juices. The 

 seeds are commonly rich in fixed oil. Several of the species are highly ornamental in cultivation.
