(Synopsis of subfamilies and tribes.) 



a. Calyx adnate to ovary: fr. 

 a berry or drupe 



to tlio 



liter 



ovary 



part of it), which in fruit 



is not a capsule but a 



berry or drupe crowned 



with the calyx-teeth : co- 

 rolla always gamopetal- 



ous. and disc epigynous : 



anthers erect, introrse : 



pollen-grains compound, 



of 4 united grains. 



Shrubs or subshrubs with 



alternate leaves

a capsule, except in tribe 



1 of sub-family 2

 (except in Cletbra). ...

 petalous : disc gen- 

 erally annular or 8-

Subfamilj 3. PYROLINE.ffi:. Anthers erect and 

 extrorse in the hud. with apex often pointed, emargi- 

 nate 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. 



Tribe 1. Clethre.t:. Ovary of the 5-merous 

 flower 3-ccIled : pollen-grains simple, shrubs or trees. 



Tribe 2. Ptrole.e. Ovary cells 5 or 4, as many

 nearly so.

 c. Ovary 10-celled, 10- 



ovuled 2. Gavlussacia. 



cc. Ovary 4-5-celIed, or by 

 false partitions from 

 the back of these 

 ceils 8-10-ce lied, 

 ovules numerous. ...3. Vaccinium. 

 DB. The ovary at first 1-3-1-2 



superior 4. Chiogenes. 



Subfamily 2. ERICINE.ffi.

\. The anthers blunt on back.. 7. Perxettva. 



Tribe 2. Axdromede.t:. 



A. Anther cells opening through 

 their whole length, not 

 appendaged : stigma 5- 

 lobed, the lobes adnate to 

 a surrounding ring or cup. 8. 

 AA. Anthers opening only at the 

 top : stigma usually en- 

 tire 



B. Calyx becoming fleshy in 

 fruit forming a berry 

 and inclosing the small 



capsule J>- 



BB. Calyx unchanged and dry 

 under the capsule. . . . 

 c. Sepals or calyx lobes 

 valvate or open in 

 the hud, never over- 

 lapping 



D. Anthers destitute of 

 a p p e nd a g e s or 



Gaultiieria. 



Subfamily 4. MONOTROPE.ff:. Herbaceous root-par- 

 asites or saprophytes, scaly, destitute of all green 

 herbage. 



DD. Anthers short and ob- 

 tuse, with 2 pores 

 topped by slender, 

 ascending awns: 

 corolla urn-shaped. .11. Axdromeda. 

 DDD. Anthers lanceolate, 

 produced into 2 

 small tubes, each

 junction with the 



anther 1.3, Pieris. 



cc. Sepals or calyx lobes 



imbricated, at least 



in the enrly bud. . . . 



D. Lvs. heath-like, small, 



thick or needle like. 



* mostly overlap- 



ping : anthers fixed 



near apex 14. Cassiope.
