308 Polemoniacca—Phlox. 
4. Ph. réptans, including Ph. vérna 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. Drummond (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 xodXa, 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. 
1. C. coccinea, syn. C. Cuvanillésii.— 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. GILIA. 
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 
Ipomdpsis, Leptosiphon, Pénzlia, ete. 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 Amcrica. The genus was named in memory of a
