381. t. 1230.—Plukn. phyt. t. 116. f. 5. A stiff, hard, procum- 
bent shrub, with ascending hardly pubescent branches. Leaves 
of the sterile branches small, decussate, obtuse; those of the 
fertile branches an inch long, linear, acute, stiff, flat or compli- 
cate, ciliated. Whorls many-flowered, disposed in spikes, which 
are sometimes interrupted. Floral leaves and bracteas broad- 
lanceolate, acute, coloured, ciliated, and closely imbricated with 
the flowers, and covering the calyxes. Calyx glabrous or 
ciliated on the nerves. Corolla purple. 
Spicate-flowered Thymbra. Fl. June, July. Clt. 1699. Shrub 
4 to 1 foot. : 
_ Cult. This is a plant well fitted for rockwork, or to be grown 
M pots among other Alpine plants. A poor stony or gravelly 
soil suits it best; for in no other soil will it survive our winter 
without shelter. The plant is readily propagated by young 
cuttings and by seed.

tridentate ; lower lip bifid ; throat pilose inside. Corolla bilabi- 
ate, with an exserted, straight tube, which is naked inside. Sta- 
mens 4, didynamous, ascending, approximate: lower ones the 
longest; anthers 2-celled : cells divaricate, spurred at top: 
spurs in both cells equal, straight, acute, and length of the cells. 
Style villous, bifid at top; lobes subulate, equal, stigmatiferous 
at top. This genus is readily distinguished by the form of the 
anthers.

bracteas shorter than the corollas; stamens exserted. Y%.? F. 
Native of North California, Douglas. This differs from P. 
Douglasii, in the stem being divaricately branched; in the 
spikes being smaller, and more numerous; and in the flowers 
being smaller. Lower calycine teeth hardly twice as long as 
the tube.
