DECANDRIA. MONOGYNIA. 275 



ous; anthers spotted, pores truncate, divergent; germ sur- 

 rounded at the base by a glandular ring. Style extreme- 

 ly short, hid in the umbilical depression of the germ; stig- 

 ma convex, orbicular, disk cloven into 5 angular segments; 

 germ somewhat conic. Capsule 5-celled; septa medial, 

 arclncially bipartile, coalescing below in the receptacular 

 axis, margins of" the valves destitute of connecting fila- 

 ments, beginning to open at the summit; receptacle o-Io- 

 bed, pendulous, lobes bipartile. Seeds similar to Pijrola. 



2. ftiaculata. — Scape 1 to S-fiov.ered, sometimes with 12 

 stamina and 6 petals, flowers white; disk of the stipe 

 which supports the filaments entirely villous; leaves ovate- 

 lanceolate, incisely serrate, discolored. Hab. Indigenous 

 also to the North West Coast of America. — Menzies. 



Probably both species of this genus will be found also 

 in East Asia and Kurope. — I'he disposition of the pores at 

 the base of the anthers in place of the summit, in this and 

 the preceding genus, adduces an additional affinity to the 

 genus Monolropa; we learn that there exists also a leaf- 

 less species of J^yrola, on the North West Coast. V. En-

391. LEDUM, i. (Labrador-tea.) 



Calix 5 -cleft. Petals 5. Stamina exserted^ 

 Capsule 5-celled, opening at the base. (Stami- 

 na also 5.) 



Low shrubs with coriaceous leaves, wliich are revolute 

 on the margin, and commonly tomentose on the under 

 surface; flowers white, in terminal corymbs, peduncles 

 long and l-flouered, bracteate at the base. 



Species. 1. h. palustre. 2. latifolium. The leaves of 

 this species are said to be a good succedanum for tea. 

 Indigenous also to Greenland. 3. buxifolhim, capsule 

 ovate, opening at the summit; leaves smooth on botli 

 sides. Probably a distinct genus, but requires further ex- 

 amination. This species is extremely abundant on the 

 highest summits of the Catawba ridge in North Carolina. 



Of this small genus L. palustre^ is also indigenous to the 

 north of Europe. 



392. CLETHRA, L. 



Calix 5-parted, persistent. Petals 5. Style 

 persistent; Stigma short and trifid. Capsule 3- 

 celled, 3-valved, enclosed by the calix.
