EIIICACE.E. 17 



19. BEJARIA. Calyx 4— >l()l)ed. Petals obovatc or spatulate, somewliat erect. Stamens 

 l:i or 14. C'ai)sule dejjressed-globose, 0-7-lobed, 0-7-valved Ironi above; the columella 

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



* * Antiiers opcninij: longitudinally from tiie apex nearly or quite to the base of the 

 cells: corolla of distinct ])etals, or in Loiaeleuriu 5-clef t : no thin-scaly strobilaceous 

 buds: leaves entire: capsule o-u- (rarely 2-) valved from above. 



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

 small, corynib(jse or fascicled : pedicels subtended by coriaceous foliaccous persistent 

 scales or l)racts : calyx 5-parted : stjle and slender filaments not declined: anthers 

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



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

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

 away with the 2 or 3 valves in dehiscence. 



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

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

 the placenta; left on the columella. 



-1^ •)— Erect shrubs, with deciduous alternate leaves : flowers larger, from leafy shoots 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 : placentas 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-()-eelled, depressed-glo- 

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



SuBORDKR III. PYROLINE^E. Caly.x; free from the ovary. Corolla poly- 

 petalous, liypogyiious, deciduous. Anthers erect aud extrofse iu the bud, with 

 apex often pointed, emargiiiate or 2-lioi'ued at base, where each cell opens by a 

 pore, in anthcsis mostly introrsely resu[)inate on the fihimeut, 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 persistent. (Proc. Am. Acad. xii. 61.) 



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

 sule of the 5-mei-ous flower 3-celled. Stigmas 3, distinct, over tlie placentae. Em- 

 bryo cylindraceous, as in Ericinecc. 



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

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

 Style filiform, persistent, eonnnonly 3-cleft at the apex: stigmas thickish and truncate. 

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

 porrect placenta> remaining attached to the upjier part of the columella. 



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

 glabrous, with evergreen foliage, one species leafless. Pollen-gi-ains 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 orhicular-jieltate, barely 

 5-crenate, concealing the very short obconical style, which is inunerst'il in the unil)ili- 

 cate sunmiit of the ovary and capsule: the latter dehis(;ent 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 widelj' spreading, 

 orbicular. Stamens 10, or sometimes 8 : filaments subulate, 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.
