THUY6PSIS (Greek, nntja-lihe) . Coniferip. Ever- 

 green ornamental pyramidal tree or shrub, with spread- 

 ing branches, the branchlets arranged in a frond-like 

 fashion^ much flattened and clothed with scale -like 

 glossy green foliage. Thuyopsis is one of the most 

 beautiful Japanese conifers, and is well adapted for 

 planting as a single specimen on the lawn wherever it 

 can be grown successfully. It is hardy as far north as 

 Mass., but usually suffers from summer drought. It 

 thrives best in a sheltered and shade<l position and in 

 moist loamy soil, and seems to grow to perfection only 

 in cool and moist climates. Prop, by seeds, also by cut- 

 tings and by grafting like Thuya. Plants raised from 

 cuttings usually grow into bushy, round-headed plants. 

 Plants .grafted on Thuya are said to be short-lived. 

 Seedlings are therefore to be preferred. The genus 

 contains only one Japanese species, closely allied to 

 Thuya and chiefly distinguished by the i-S ovules 

 under each scale. The yellowish white, close and 

 straight-grained wood is very durable and is used in 

 Japan in boat- and bridge-building. 



dolobrata, Sieb. & Zucc. (Thuya dojobritta, Linn). 

 Pyramidal tree, attaining 50 ft. or sometimes shrubby: 

 branchlets irregularly whorled or scattered, horizontally 



tire. The calyx is ovate or ovoid, hairy in the throat, 

 .o-toothed and 2-lipped, about 10-13-nerved, usually de- 

 clined in fruit ; corolla small, 2-lipped, the upper lip 

 2-toothed and erect, the lower one 3-cleft and spreading; 

 stamens 4, mostly in 2 pairs and usually exserted. The 

 flowers are mostly in shades of blue or purple, but are 

 sometimes white; they are borne in whorls, foi-ming a 

 terminal spike or head-like cluster. Thymes are erect 

 or prostrate plants with strong mint-like odor. Most of 

 the species are grown as a ground cover on banks, in 

 borders or rockwork. The creeping or prostrate habit, 

 ability to persist in dry places and poor soils, and the 

 colored or woolly foliage of some species make them 

 adaptable to a variety of uses. The common T. Ser- 

 pyUu^n is evergreen. T. vuJquris is the Thyme of sweet 

 herb gardens, being prized in cookery. All Thymes are 

 easily propagated by means of division, although seed- 

 lings may sometimes be used to renew plantations of 

 some of "the species, particularly of T. vulgaris. Sev- 

 eral names occur in American catalogues, all of which 

 seem to be referable to three species, one of which is 

 not a true Thymus. See Sage, where general culture 

 of such herbs is given. 



vulgaris, Linn. Common Thyme. Plant erect, 

 the base sometimes decumbent, 1-2 ft., the branches 

 stiff and woody, usually white-pubescent: Ivs. sessile, 

 linear to ovate-lanceolate, acute, the margins more or 

 less revolute: fls. small, lilac or purplish, in terminal 

 interrupted spikes. S, Eu.-An old garden plant, being 

 grown as a sweet herb. The leaves and shoots are used 

 for seasoning. It is well to renew the plants from seeds 

 every two or three years. There are varieties with broad 

 and narrow leaves.
