THY 



tips, it has three ocelli in the crown, 

 the body is hairy, the tip pointed and 

 bristly, the wings are shorter than the 

 body in the male, lying parallel on the 

 back when at rest, narrow, especially 

 the under ones, and fringed, the hairs 

 longest beneath and at the point, tips 

 of feet dusky. It is destroyed by the 

 same means as T. adonidum.

THU'JA. Arbor Vitse. (From thyon, 

 a sacrifice ; the resin used as incense 

 in eastern sacrifices. Nat. ord., Conifers 

 [Pinacese]. Linn., 21-Moncecia 10-Ztec- 

 andria.) 



Hardy evergreen trees. Seeds, which ripen 

 freely, or by cuttings ; the seeds are best sown 

 in April, slightly covered, and if a frame or 

 hand-light can be set over them, all the better ; 

 moist soil suits the most of them, a few of the 

 tenderest will require protection until they 

 become some size.

THUNBE'EGIA. (Named after C. P. 

 Thunberg, the celebrated botanist. Nat. 

 ord., Acanthads [ Acanthacese] . Linn., 

 l-I)idynamia 2-Angiospermia.) 



Stove evergreen climbers. Seeds, in early 

 spring, in a strong, moist, sweet hotbed ; cut- 

 tings, any time before the end of August, in 

 sandy soil, under a bell-glass ; fibry loam and 



Eeat, with a little rotten dung and lime rub- 

 ish. Winter temp., 48to6o; summer, 60 



to 80. As they are very subject to red spider, 

 perhaps the best mode of treating these fine 

 plants, is to grow them as annuals, throwing 

 the plants away in the end of autumn. If pre- 

 served, the flowers of sulphur and the syringe 

 must hardly ever have a holiday. Indeed, the 

 syringe and a little shade are necessary to their 

 health in summer.

 to a Thyme-like plant. Nat. ord., Lip- 

 worts [Lamiacese]. Linn., l^-Didy- 

 namia I-Gymnospermia. Allied to Me- 

 lissa.) 



Half-hardy evergreens. Seeds, in April; or 

 cuttings under a hand-light, in June; sandy 

 gravelly loam. Nice rockwork plants. Ciliata 

 is the prettiest ; require a cold pit in winter.

 tings, or divisions, in March or April; sandy 

 loam suits them all best. 7*. vulgaris is our 

 common pot-herb thyme. For culture see Sage.
