ERICACEAE. 17 



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

 12 or 14. Capsule depressed-globose, 0-7-lobed, 6-7-valved from above; tlie columella 

 short. Flowers (in om-sj racemose : no strobilaceous buds. 



* * Anthers opening longitudinally from tlie apex nearly or quite to the base of the 

 cells : corolla of distinct jietak, or in Luisi-Ji-urin :>Llef t : no thin-scaly strobilaceous 

 buds : leaves entire : capsule u-5- (rarely L'-) valved from above. 



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

 small, corymbose or fascicled : pedicels subtended by coriaceous foliaccous 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 tlie columella, but carried 

 away with the 2 or 3 valves in dehiscence. 



21. LOISELEURIA. Corolla broadly campanulate, deeply .5-cloft. J^tamens 5 : filaments 

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

 the placenta; left on the columella. 



■t— -i— 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 (Z 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 5-6-celled, depressed-glo- 

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



Suborder III. PYROLlXE^^i!. Calyx free from the ovary. Corolla poly- 

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

 ape.x often pointed, emarginate or 2-horneil 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 persistent. (Proc. Am. Acad. xii. 61.) 



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

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

 bryo cylindraceous, as in Ericlnece. 



2,4:. CLETHRA. Petals -5, obovate or obcordate. Stamens 10: anthers sagittate and 

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

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

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

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



TuiBK 11. PYROLEJE. 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 (•). 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 style, wliich is immersed ui the urabili- 

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

 valves not woolly on the edges. 



25. CHIMAPHILA. Petals 5, widelj- 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. 4 



26. MONESES. Flowers solitary, sometimes 4-n)erous, regular. Petals widel.v spreading, 

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