probably from Teucer, King of Troy, who is said to have 
first used the plant medicinally). Germander. Includ- 
ing Polium, Scordium, and Scorodonia. ORD. Labiate. 
A large genus (nearly 100 species) of greenhouse or 
hardy herbs, sub-shrubs, or shrubs, of variable habit, 
dispersed over the temperate and warmer regions of the 
lobe. Calyx tubular or campanulate, rarely inflated, five- 
_ ‘toothed ; corolla limb quasi-bilabiate, obliquely five-lobed, 
the two upper lobes very small, the two lateral lar 
' ll, ger, 
the lowest largest; stamens four; whorls two or rarely 
sed in spikes, racemes, or

Nutlets obovoid, reticulate-wrinkled. Leaves

entire, toothed, or incised, sometimes multifid ; floral ones 
conformed or reduced to bracts. T. Botrys, T. Scordiwm 
(Water Germander), and T. Scorodonia (Wood Sage), are . 
British plants. T. Chamedrys, an escape from gardens, 
has become naturalised. T. Pseudo-Scorodonia (Bastard 
Wood Sage), an inconspicuous species nearly allied to 
the British T. Scorodonia, is now and then met with in 
gardens. Few of the species have any horticultural 
merit, but several are of medicinal value. All thrive in 
any moderately good soil. The shrubs may be increased 
by cuttings, inserted in sandy soil, under a glass, in 
spring or summer; the perennials by divisions. 
T, betonicum (Betony-like). /l. purplish ; corolla tube exserted, 
pubescent outside, the throat inflated and incurved; whorls two- 
flowered, secund, loosely racemose; racemes 3in. to 6in. long. 
May to August. l. ovate-oblong, lin. to lżin. long, on rather 
long petioles, crenate, woolly below or on both sides ; floral ones 
shorter than the calyx. Branches cano-tomentose. h. 14ft. 
Madeira, 1775. Greenhouse, evergreen shrub. (B. M. 1114.) 
T. bicolor (two-coloured). fl. blue; peduncles short, axillary, 
one-flowered, the upper ones sub-racemose. July, J. ovate, 
oblong, or lanceolate, nearly lin. long, entire or cut, sometimes 
trifid ; young ones often linear, entire or trifid; floral ones 
usually exceeding the flowers. Branches lft. to 2ft. long, acutely 
tetragonal. A. lft. Chili, 1826. Greenhouse, glabrous peren- 
nial. SYN. T. orchidewm (B. R. 1255).
