PAPAVERACKJB. 32 CHELIDONIUM. 



appendage extending lengthwise inside, and the cordate lamina as above, with 

 inversed hairs at the mouth. Their capacity, when of ordinary size, is about a 

 wine-glass, and they are generally full of water. The scape is a foot or more 

 high, round, smooth, supporting a large, nodding flower, which is almost as 

 curious in structure as the leaves. June. Per. Side-saddle Flower. 



ORDER XII. PAPAVERACE.E. The Poppy Tribe. 



Cal. — Sepals 2, rarely 3, deciduous, imbricated in rcstivation. 



Ck>r. — Petals 4, rarely 5 or 6, hypog-ynous. 



jSta.— Often numerous, but some multiple of 4, rarely polyadelphous. Anth. innate. 



Oi'o, — Solitary, style short or 0. Stig. 2, or if more, stellate upon the flat apex of ovary. 



Fr.— Either pod-shaped, with 2 parietal placentfE, or capsular with several. 



Sds. — Very numerous, minute. 



More than two-thirds of the genera of this order, which is small, are native of Europe. 

 Inhabit, they are herbaceous or shrubby, and hav£ a milky or turbid juice. Flowers mostly 

 showy, but never of a blue color. Almost all the genera contain active, narcotic properties, 

 principally resident in the turbid juices. The seeds are commonly rich in fixed oil. Thu 

 order contains many highly ornamental, cultivated plants.

1. SANGUINA'RIA. 



Calyx 2-sepaled, caducous ; corolla 8-petaIed ; stamens nu- 

 merous; stigma 1, 2-lobed, sessile; capsule pod like, 1-celled, 

 2valved, many-seeded. 



Lat. savffuis, blood ; all parts of the plant when wounded discharge a blood- 

 colored fluid. Sep. concave, falling as soon as the corolla expands. Petals 

 generally 8, in two series, the 4 outer ones longer, giving the flower a quad- 

 rangular outline. Anth. obi. yellow. Sty.O. Pod obi. ovate, acute at each end. 



S. Canade'nsis. 



Lcapes solitary, radical, reniform ; scope naked, 1 -flowered, sheathed at base; 

 petals spreading, regular. The only species. An interesting flower of fertile 

 woods, groves, &c. appearing in early Spring. Ilhizoma fleshy, tuberous, 

 and when broken or bruised, as well as every other part of the plant, exudes 

 a blood-colored fluid. From each bud of the root-stock there springs a single, 

 large, glaucous leaf, and a scape about G inches high, with a single flower. 

 The whole plant is smooth. The leaf is kidney shaped, with roundish lobes 

 separated by roundish sinuses. The flower is white, square and on a round 

 scape. It is scentless and of very short duration. The juice is emetic and 

 purgative. April. Per. Blood Rout.
