134 ORDER ANGIOSPERMIA. 



the seeds numerous, surrounded with a membranace- 

 ous inflated vesicle. The Bartsia pallida, of the 

 White Mountains of New Hampshire, is another spe- 

 cies of Euchroma, characterized by having entire nar- 

 row leaves, subovate, pale pink colored bractes, some- 

 times almost white, slightly toothed at the extremity ; 

 and the teeth of the calyx entire. 



The Epiphegus, or Beech-drops, of the natural order 

 OROBANCHEiE, and formerly included in the genus 

 Orobanche, may well be known, as its generic appella- 

 tion implies, by its uniform parasitic situation near the 

 roots, and beneath the shade of Beech trees. The 

 flowers, on the same plant, are polygamous, or fertile 

 and infertile, though not as in true monoecious plants 

 reciprocally necessary to the perfection of the fruit, 

 for the first flowers produced, for some time, are all 

 perfect, and the latest developed flowers alone are 

 sterile. The calyx is very short, 5-toothed (and so 

 an exception to our section). The corolla of the in- 

 fertile flower (yellowish with purple stripes) is ringent, 

 compressed, and 4-cleft ; having the lower lip flat ; 

 the corolla of the fertile flower minute, 4-toothed, 

 and very deciduous ; the capsule truncate, oblique 

 to its axis, l-celled, imperfectly 2-valved, and opening 

 only on one side. This curious plant, thickly scatter- 

 ed, flowering about September, is entirely leafless, 

 and destitute of verdure, repeatedly but simply branch- 

 ed, with the flowers distant and all over the stem.
