tire, glabrous ; flowers solitary, lateral. J? . S. Native of 

 Africa, on the coast of Zanquebar. C. Zanquebarica, Lour. coch. 

 p. 195. Flowers pale. This plant agrees with the present 

 genus in the calyx being 6-cleft, in the corolla being 6-lobed, in 

 the stamens being 6, and in the capsule being 6-celled ; but 

 differs in the capsule dehiscing at the base, not at the apex, in 

 the flowers being lateral, and in the leaves being alternate. 



Zanquebar Canarina. Shrub climbing. 



Cult. C. campanulata is very desirable, as it flowers 

 in autumn and winter, when few other plants are in bloom. 

 After flowering the stem dies down, and the root continues dor- 

 mant all the summer, when it needs but little water. When the 

 stem begins to push forth the plants had better be removed to the 

 stove, as they will not flower so abundantly in the green-house. 

 A light loamy soil, or a mixture of loam and peat, is the best 

 soil for it ; and the plant is readily increased by dividing at the 

 root or by cuttings, planted in the same kind of soil under a 

 hand-glass. The C. Zanguebdrica being a stove shrub will 

 grow in the same kind of soil recommended for the first species, 

 and will be easily increased by cuttings.

 Corolla 5-lobed at the apex (f. 127. d.~), large, funnel-shaped. Sta- 

 mens 5 (f. 127. a.), free ; filaments broadest at the base. Stigmas 

 3-5 (f. 127. 6.). Capsule 3-5-celled, dehiscing by 3-5 valves at 

 the apex, which are septiferous in the middle ; cells when 5 alter- 

 nate with the calycine lobes and stamens. Seeds ovoid, larger 

 than in any genus of the order, shining, but not angular. 

 Perennial usually glaucescent herbs, natives of Eastern Asia. 

 Leaves alternate or nearly opposite, sessile, of a middle size ; 

 upper ones the smallest. Flowers few, terminal, solitary, pe- 

 dunculate.

 5-celled. y.. H. Native of Da-

2 P. HOMALLA'NTHINUM (Alph. D. C. mon. p. 126.) plant 

 rather pilose at the top ; leaves lanceolate or linear-lanceolate ; 

 corolla deeply 5-cleft; stigmas 3; capsule 3-celled. I/. H. 

 Native of the east of Siberia, near Ijiga, ex Fisch. ; of 

 Kamtschatka, ex Redowsk ; and of China, ex Sir G. Staunton. 

 Stems simple. Leave's coarsely and unequally serrate-toothed,

Enual-Jlowered Pfetycodon. PI. 5 to 1 foot. 



Cult. These species of Plalycodon are neat elegant plants 

 when in blossom. They do best in pots in a mixture of sand 

 and peat, placed among other alpine plants ; they will also 

 grow very well planted in a peat border. We know of no way 

 of increasing them but by seeds. 



VIII. MICROCO'DON (from picpoe, mikros, small, and 

 Kwliav, kodon, a bell ; in reference to the shape and smallness 

 of the flowers). Alph. D. C. mon. p. 127. Campanula spec. 

 Eklon. Wahlenbergia spec. Schrad. 



LIN. SYST. Pentdndria, Monogynia. Calyx 5-cleft. Corolla 

 5-lobed at the apex, small, cylindrical, permanent. Stamens 5, 

 free ; filaments very slender, not expanded at the base. Style 

 filiform ; stigmas 5. Capsule 5-celled, dehiscing by 5 valves 

 at the apex ; cells alternating with the calycine segments and 

 stamens. Seeds ovoid, small, shining, but not angular. Humble 

 annual herbs, natives of the Cape of Good Hope. Leaves 

 alternate or nearly opposite, small, narrow, sessile : superior 

 ones rather the longest. Branches at the base of the plant oppo- 

 site and diverging. Flowers almost sessile. Tube of calyx 

 spherical and very hairy. 



1 M. GLOMERA V TUM (Alph. D. C. mon. p. 127. t. 19.) stem 

 branched ; branches simple ; leaves linear, acuminated ; flowers 

 glomerate, terminal. O. H. Native of the Cape of Good 

 Hope. Campanula hispidula, Eklon, in herb. Dunant, but not 

 of Lin. Campanulaceas, Burch. cat. pi. afr, austr. no. 189. 

 Stems rather pilose. Leaves somewhat denticulated, rather 

 hairy. 



Glomerate- fiowered Microcodon. PI. to -j foot. 



2 M. SPARSIFLORUM (Alph. D. C. mon. p. 128.) stem branch- 

 ed : branches subdivided ; leaves linear-lanceolate ; flowers 

 solitary. O- H- Native of the Cape of Good Hope. Wahlen- 

 bergia hispidula, Schrad. in herb. D. C. Campanula hispidula, 

 Link, enum. p. 215. Stem pilose. Leaves rather pilose. 

 Flowers solitary towards the tops of the branches, not terminal, 

 but rising from the axils of the upper leaves or bracteas. 



Scattered-fiowered Microcodon. PI. \ foot. 



Cull. The seeds of these plants should be raised on the hot- 

 bed ; and when the plants are of sufficient size they may be 

 planted out into the open border in May in a warm sheltered 

 situation.
