308 "" Potemoniaccce Phlox. 



4. Ph. reptans, including Ph. verna and Ph. stolonifera. 

 A creeping not tufted species, with obovate or rotundate rather 

 thick nearly smooth leaves. Flowering stems from 6 to 12 

 inches high, clammy-pubescent. Flowers reddish purple, in 

 small cymes ; lobes of the corolla entire. North America. 



5. Ph. Drummondii (fig. 172). This is the only annual 

 species in cultivation, and a charming dwarf plant, now, perhaps, 

 more universally grown than any other of its class. It is equally 

 rich in varieties with the perennial species, and one of the most 

 profuse-blooming plants we can call to mind. There is about 

 the same range of colour in the varieties, and it includes some 

 very handsome streaked and marbled ones. It is a native of 

 Texas, and not quite so hardy as the other species. 



2. COLLOMIA 



Dwarf annuals with narrow alternate leaves and dense 

 terminal heads of small red or buff flowers. Calyx deeply 5- 

 lobed, campanulate. Corolla salver-shaped, with a long slen- 

 der tube. Cells of the capsule 1- or 2-seeded. A small genus 

 whose species are confined to the western side of North and 

 South America. The name is from the Greek /co\\a, glue, in 

 reference to the glutinous coating of the seeds. When the 

 seeds are put into water this mucous coating expands and 

 forms a cloud around them. 



i.C. coccinea, syn. C. * Cavanillesii. This plant grows 

 about a foot high, and is the best for ornamental purposes. 

 The leaves are sessile and lanceolate, or oblong, and as well as 

 the stems clothed with a somewhat clammy pubescence. The 

 flowers vary from brick-red to buff. A native of Chili. 



C. grandiflora, a Californian species, has rather larger 

 flowers, about 10 lines long, of a buff or pink colour. 



3. GlLIA. 



This genus in its widest sense includes many species 

 differing greatly in habit, but almost identical in structure. 

 These are known in gardens under the generic names of 

 Ipomopsis, Leptosiphon, Fenzlia, etc. The principal charac- 

 teristic of these plants is to have several angular seeds in each 

 cell of the capsule, and the stamens inserted at the mouth of 

 the corolla-tube. The corolla varies from salver-shaped to 

 campanulate. The species are all annual or biennial, and 

 natives of America. The genus was named in memory of a
