3. CHIOGENES. Stamens 8 ; anthers with short cells minutely 2-pointed, and opening 



by a large chink down to the middle. Ovary 4-celled, in fruit a white many-seeded 

 berry. 



II. HEATH SUBFAMILY PROPER; shrubs or small trees 

 with calyx free from the ovary. 



* Monopetalous (or in one of No. 12 with two of the petals nearly separate). 

 +- Fruit berry-like, containing 5-8 seeds or very small stones. 



4. ARCTOSTAPHYLOS. Corolla urn-shaped, 5-toothed, inclosing the 10 stamens; 



their anthers opening at the top, and 2-awned on the back. Drupe 5-10-seeded. 

 Calyx dry underneath. Leaves alternate. 



5. GAULTHERIA. Corolla oblong or short-cylindrical, 5-toothed. Anthers 10, 4-awned 



or 4-pointed at top, opening only there. Fruit a dry and many seeded pod, but 

 inclosed in the calyx which becomes thick and fleshy, so that the fruit imitates a 

 berry, but has a dry pod inside. (Lessons, Figs. 866, 367.) Leaves alternate, broad, 

 often spicy-aromatic, evergreen. 



<- -i- Fruit dry, not berry like ; calyx separate from the pod. 

 H- Corolla salver shaped, 5-lobed; anthers opening lengthwise, not appendaged. 



6. EPIG^EA. Sepals 5, thin and scale-like, ovate-lanceolate, style slender. Leaves ever- 



green, reticulated, roundish. 



H- ++ Corolla cylindrical, urn-shaped, ovate, or globular, very rarely bell-shaped, the 

 or$ce b-loothed ; anthers opening wholly or mainly at the top. 



7. ANDROMEDA. Calyx valvate in the early bud ; no bractlets. Corolla various. Pod 



globular or short-ovate, 5-valved, loculicidal. Shrubs. 



8. OXYDENDRUM. Calyx valvate in the bud ; no bractlets. Corolla ovate. Anthers 



awnless. Pod conical or pyramidal, 5-valved, loculicidal. Tree. 



9. LEUCOTHOE. Calyx of 5 almost separate sepals a little overlapping in the bud. 



Corolla ovate-oblong or almost cylindrical. Anthers without tubular tips. Pod 

 flattish from above, 5-valved, loculicidal. Shrubs. 



10. CASSANDRA. Calyx of 5 ovate and acute rigid sepals overlapping in the bud, and a 



pair of similar bractlets at its base. Corolla almost cylindrical. Anthers with tubular 

 tips to the cells, and no awns on the back. Pod flattish from above, when ripe split- 

 ting into an outer layer of 5 valves and an inner cartilaginous one of 10 valves. 

 Shrub, with leaves rather scurfy. 



H- -H- -H- Corolla (usually large) open bell-shaped, saucer-shaped, funnel-form, etc., 

 5-lobed or cleft ; anthers short, without aicns or other appendages, opening only 

 by holes at the top ; filaments long and slender, as is also the style ; pod septi- 

 cidal; leaves entire. 



= No scaly buds; bracts green, firm and persistent. 



11. KALMIA. Corolla broadly open, slightly 5-lobed, and with 10 pouches in which the

 up and discharge the pollen. Pod globular. Leaves evergreen. Flowers in umbels 

 or corymb-like clusters.

 like bracts or bud scales falling as the blossoms are developed. Calyx often
