regular, 4 to 5-cleft, the petals rarely distinct. Stamens as many or twice as many 

 aa the petals, free, hypogynoua. Anthers 2-celled, generally open by pores, often 

 appendaged. Pollen (except iu Monotropese) compounded of 4 united grains. Mn- 

 hryo straight, lying in the axis of, or in the end of fleshy albumen. Illust. in figs 

 38, 45, 110, 203, 320, 345, 350, 355. 



Oenera 66, species 10S6, dispersed throughout all countries, but comparatively rare hi the 

 toiTid zone. The true Ericaceie (Heaths), are chiefly natives of the Oape of Good Hope, there 

 being none in Asia, New Holland, and but ono or two in America. The Tribe Vaccineae are 

 chiefly natives of N. America. 



Pp&perties. — The Heathworts are, in general, astringent and diuretic. Some of them yield a 

 stiiaulating and aromatic resinous matter. The Bearberry, (Aj-ctostaphylos Uva-ursi) is a well 

 known remedy in nephritic complaints. An infusion of the leaves is astringent, demiilceDt 

 and diuretic. Similar properties arc also possessed by the Pipsisaiwa (Chimaphlia umbellata). 

 The species of Rhododendron and Kalmia are pervaded by a narcotic principle, rcndei-ing them 

 (particularly their leaves) often actively poisonous. The honey collected from their flowers by 

 the bees appears so have been so to some of the soldiers in the retreat of the immortal ten thou- 

 sand (Senophon's Anabasis). The berries of the Vacoineaj (Whortleberries, Blueberries and 

 Cranberries,) and of Ganlthenia procumbens (spicy Wintergreen) are esculent and wholesome. 



Tho true position of oar siuborders Cyrillese and Galacinaj is not known. We follow De Can- 

 dolle i)i appending them to Erlcaeea} rather from convenience, as their habit certainly points to 

 this order.
