Oedee LXXVII. ERICACE^. 



Trees, shrubs, or some perennial herbs, with simple and undivided leaves des- 

 titute of stipules and commonly alternate, symmetrical (4-5-merous) and perfect 

 flowers, eitheV regular or occasionally irregular, stamens free or nearly free from 

 the corolla and as many or more commonly twice as many as its lobes or petals, 

 the anthers 2-celled and in most opening by pores (in many awned or otherwise 

 appendaged), the pollen composed of 4 united grains (except in the fourth suborder 

 and a part of the third), and the style single. Calyx imbricated or sometimes 

 valvate in the bud, free and the corolla and stamens hypogynous, except in the 

 first suborder. Corolla not rarely 5- (or 4-) petalous, in the bud imbricated or in 

 some convolute. Anthers introrse, or in the PyroUnece primarily and normally 

 extrorse, but in anthesis introrsely inverted! Ovary 4-10-celled (or the cells 

 rarely 3 or 2 and fewer than the petals), with placentas in the axis (a tribe of 

 Monotropex excepted) ; the ovules numerous, generally very numerous, sometimes 

 solitary, anatropous. Stigma not rarely girt with a ring, entire or merely lobed ; 

 only in Clethra is the apex of the style 3-cleft. Fruit capsular, baccate, or dru- 

 paceous. Embryo small or minute, in fleshy albumen ; the cotyledons small and 

 short or undeveloped. [EricacecB, Vaccimacece, Pyrolacea, & MonotropecB of 

 authors, all merging into one large family.) 



Suborder I. VACCINIEJ3. Calyx-tube adnate to the ovary (or to the 

 greater part of it), which in fruit is baccate, either a true berry or drupaceous, 

 crowned with the calyx-teeth. Corolla always gamopetalous, and with the disk
