ERICACEAE. 19 



ture, or still more to those of Linaria Cymbalaria, rarely above J inch 

 across, alternate, but the 2 uppermost ones or bracts (which are 

 narrow, hastate or sub-rhomboidal) often opposite. Corolla g inch 

 long, much longer than broad, bright delicate blue. Capsule very 

 small, globular, scarcely the half of it free. Plant pale-green, 

 glabrous. 



Ivy-leaved Bell-jloioer. 



German, EpIteubMllrige Wahleribergie. 



This beautiful delicate little plaut is as attractive as any of its predecessors, — not 

 so much on account of its blossom as from the graceful manner of its growth, forming 

 festoons of ivy-leaved wreaths around rocks, or trees, or any other object near which it 

 is placed. 



EXCLUDED SPECIES. 

 CAMPANULA SPECULUM. Linn. 



This plant, the Specularia Speculum (Al. D. C.) of many authors, 

 is said to have been sown in cornfields in the undercliff of the Isle 

 of Wight by the late Dr. Bromfield : I am not aware if it still 

 maintains its ground there. 



ORDER XLIIL— ERICACEAE. 



Shrubs or small trees, very rarely herbs, with alternate or oppo- 

 site or verticillate often evergreen leaves, -without stipules : rarely 

 leafless, and with fleshy scales. Flowers perfect, regular or nearly 

 so, usually red, pink, purple, yellow or white, axillary or terminal, 

 solitary or aggregated. Calyx regular, with 4 or 5 segments, gene- 

 rally free from the ovary, more rarely furnished with a tube which 

 adheres to the ovary. Corolla regular, often sub-globular or ovoid, 

 monopetalous with 4 or 5 lobes, more rarely of 4 or 5 distinct 

 petals, inserted on the torus (hypogynous) when the ovary is 

 superior, or at the summit of the calyx-tube when it is inferior. 

 Stamens 8 or 10, rarely 4 or 5 (in the latter case alternate with 

 the lobes of the corolla), inserted on the torus within the corolla ; 

 filaments not adhering to the lobes of the corolla, free, or rarely 

 united towards the base ; anthers 2-celled, free, almost always 

 opening at the top by 2 pores, in one genus splitting transversely.
