ERICACEAE. 17 



1 9. BE JARIA. Calyx 4-5-lol)ed. Petals obovate or spatulate, somewhat erect. Stamens 

 12 or li. Capsule depressed-globose, G-7-lobed, (>-7-valved I'ruiii above; the columella 

 short. Flowers (in ours) racemose : no strobilaceous buds. 



* * Anthers openinj? longitudinally from the apex nearly or quite to the base of the 

 cells : corolla of distinct i)etals, or in Loisclc.uria 5-cleft : no thin-scaly strobilaceous 

 buds: leaves entire: capsule 3-5- (rarely 2-) valved from above. 



•t— Low and small-leaved evergreens : coriaceous persistent leaves mostly opposite : flowers 

 small, corymbose or fascicled : pedicels subtended by coriaceous foliaceous persistent 

 scales or bracts : calyx 5-parted : style and slender filaments not declined : anthers 

 globose-didymous : seeds oval, with a thin close coat. 



20. LEIOPHYLLUM. Petals 5, obovate-oblong, spreading. Stamens 10 : filaments and 

 style filiform, exserted. Placenta? borne on the middle of the columella, but carried 

 away witli the 2 or 3 valves in dehiscence. 



21. LOISELEURIA. Corolla broadly campanulate, deeply 5-cleft. Stamens 5: filaments 

 and style stout-filiform and included. Capsule 2-3-valved, and valves at length 2-cleft ; 

 the placentaj left on the columella. 



■i— -(— Erect shrubs, with deciduous alternate leaves : flowers larger, from leafy slioots of 

 the season : anthers oblong : filaments flat and subulate or linear : style long, more or 

 less declined and incurved, thickened at the apex and annulate around the discoid 

 stigma : placentae persistent on the short columella : seeds with a loose cellular or 

 fungous coat. 



22. ELLIOTTIA. Petals (3 to 5) mostly 4, long and narrow. Stamens as many or twice 

 as many : filaments short. Flowers in conspicuous terminal racemes or panicles. 



23. CLADOTHAMNUS. Petals 5, oblong, spreading, equalled by the somewhat folia- 

 ceous sepals. Stamens 10 : filaments dilated below. Capsule 5-()-celled, depressed-glo- 

 bose. Flowers solitary, terminating short leafy branches or sometimes axillary. 



Suborder III. PYROLINE^. Calyx free from the ovary. Corolla poly- 

 petalous, hypog3'iious, deciduous. Anthers erect and extrorse in the bud, with 

 apex often pointed, emarginate or 2-horned at base, where each cell opens by a 

 pore, in anthesis mostly introrsely resupinate on the filament, so that the really 

 basal pores become apical and the point or apex basal. Disk obsolete or obscure. 

 Fruit a loculicidal capsule. Seeds with a loose cellular coat. Sepals and petals 

 imbricated in the bud ; the former jjersistent. (Proc. Am. Acad. xii. 61.) 



Tribe I. CLETIIRE^E. Shrubs or trees. Pollen-grains simple. Ovary and cap- 

 sule of the 5-merous flower o-celled. Stigmas 3, distinct, over the placentse. Em- 

 bryo cylindraceous, as in Ericlnece. 



24. CLETHRA. Petals 5, obovate or obcordate. Stamens 10 : anthers sagittate and 

 pointed, after inversion obsaggitate, the diverging lobes opening by a chink or large pore. 

 Style filiform, persistent, conmionly 3-cleft at tlie apex : stigmas thickish and truncate. 

 Capsule globose or 3-lobed, 3-valved, and the valves at length 2-cleft ; the many-seeded 

 porrect placentai remaining attached to the upper part of the columella. 



Tribe II. PYROLE^E. Herbs or nearly so, from perennial slender rootstocks, 

 glabrous, with evergreen foliage, one species leafless. Pollen-grains compound. 

 Cells of the ovary and capsule as many as the petals or sepals (5, or rarely 4) : 

 valves of the capsule remaining attached to the columella. Seed-coat very loose 

 and cellular, enclosing a small nucleus. Embryo very minute. 



* Stems leafy : flowers corymbose or sometimes solitary : stigma orbicular-peltate, barely 

 5-crenate, concealing the very short obconical stjde, which is inmiersed in tlie umbili- 

 cate sunmiit of the ovary and capsule: the latter dehiscent from above downwards : 

 valves not woolly on the edges. 



25. CHIMAPHILA. Petals 5, widely spreading, regular, orbicular, concave. Stamens 

 10: filaments short, dilated and mostly hairy in the middle. 



* * Scape naked or leafy only at base : style mostly elongated. 



26. MONESES. Flowers solitary, sometimes 4-merous, regular. Petals widely spreading, 

 orbicular. Stamens 10, or sometimes 8: filaments suludate, naked. Style straight : stigma 

 large, peltate, and with 5 or sometimes 4 narrow (at first erect, at length radiating) lobes. 

 Valves of the capsule not woolly on the edges.
