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

 aa the petals, free, hypogjnous. Anthers 2-CGlled, generally open by pores, often 

 appendaged. Pollen (except in Monotropea;) compounded of 4 united grains. Bm- 

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

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



Genera 66, fipecies lOSC, dispprscl throughout all countries, but comparatively rnre in the 

 torrid zone. The true EiicacL-re (lluiitUs), are chiefly natives of the (Jape of Good llupe, there 

 being none in Asia, New Holland, and but one or -two in America, 'i'he Tube Vatcineffi are 

 ohiefly natues oC N. America. 



l*roperties.~Tho Ileathworts arc, in general, astringent and diuretic. Some of them yield^a 

 stimulating and aromatic resinous matter. The Bearberry, (Arctostaphylua Liva-uibi) is a well 

 knowp remedy in nt-phritic complaints. An infusion of the leaves U nbtringeiit, demulcent 

 and diuretic. Similar properties arc also possessed by the Pipsissiwa (Ghimii|>lilia umbellata). 

 The species of PJiododendron and Kalmia arc pervaded by a narcotic principle, rendeiing them 

 (particulai'ly their leaves) often actively poisonous. The lioney collected fioin Iheii- Howers by 

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

 sand (Xenojilion's Anabasis). Tlie bt-rries of the Vaccineie (Whortlebeniea, Jbhieberries and 

 Cranben ies,) and of Gaultberia procnmbens (spicy Wintergreen) are esculent and ^\ liolesome. 



The trne position of our suborders Cyrilleai and Galacina; is not known. We lotiow De Can- 

 dolle in appending them to Ericaceae rather from convenience, aa their habit curlainly points to 

 tbis order.
