4. ROSMARINUS. 
A genus of one South European species, a familiar shrub in 
gardens. It is technically distinguished by its coloured bila- 
biate calyx and corolla with two exserted stamens having a 
reversed tooth on each filament. The name is a compound of 
ros, dew, and marinus, sea. 
1. R. officinalis. Rosemary.—_A dense branching shrub with 
linear sessile leaves, the edges recurved. Flowers pale blue 
or white. There are several varieties distinguished by name: 
as R. off. latifolius, R. off. foliis atreis, and R. off. foliis 
argénteis. 
The genus Thymus offers little in the ornamental vay, but 
most of the species are agreeably fragrant, and will thrive in 
dry rocky places ; some of the variegated varieties, as 7. citri- 
odérus vuriegdtus, of nurserymen, are very neat. 
5. MONARDA. 
A small senus of ercet herbs with simple toothed leaves and 
showy flowers in close heads of whorls surrounded with bracts. 
Calyx tubular, elongated, nearly equally 5-toothed. Corolla long 
and slender, deeply bilabiate; lips narrow, nearly equal and 
slightly toothed. Stamens 2, ascendine, the spreading anther- 
ah cells confluent at the junction. 
The species are all from North 
America. Dedicated to Monardez, 
a Spanish botanist. 
1. WW. didyma (fig. 199). Os- 
weyo Tca or Bee Balm.—A 
slightly hairy perennial about 2 
feet high with showy scarlet or 
bright red flowers and bracts. 
This flowers in Summer, and is 
by far the showiest in cultiva- 
tion. The detached corolla in 
the cut is about one-quarter of 
the natural size. 
M. fistulosa, Wild Bergamot, 
has narrower leaves and smaller purple, pink or white flowers. 
Pruncdila grandiflora is very near our native Self-heal, P. 
vulycvis, but the flowers are much larger. There are purple, 
violet, and white varieties. This genus is distinguished by its
