passing through the winters at New York City, but 
not reliably hardy north of Virginia. L. dentata 
and some others endure great drought and Califor- 
nia ought to suit them admirably.

Pogosteinon has 32 species scattered through 
the Malayan countries from India to Japan. P. 
Patchouli yields by the distillation of its young 
shoots and leaves a perfume which seems to be 
popular with American women. 
Conianthosphacc is a genus of Japanese shrubs in 
four species — some with yellow flowers. 
Pcrilla Nankinensis with dark inky purple 
leaves is an annual used as a summer bedder. It 
naturalizes more or less in the middle states, and 
so does C. ocimoides. 
Mentha “mint” has a vast number of so called 
species described of which maybe 30 are good. 
Some variegated forms are ornamental. 
Origanum “marjoram” has 30 species. 
Thymns “thyme” about 40 species with some 
ornamental flowering and variegated forms. T. 
serpyllum makes a fine sod in the North Eastern 
States, but discolors with the first frost. 
Hyssopus “hyssop” is probably monotypic, 
varying in foliage and the colors of the flowers. It 
is quite a hardy plant used in Canada in lieu of box 
edging. 
Micromeria is a genus of small evergreen shrubs 
or perennial herbs in 60 species natives of North 
West and South America, the Canaries, tropical 
Africa and the Mediterranean regions, therefore 
adaptable to California and the south of England. 
Calamintha is a genus of hardy perennials scat- 
tered in 40 species over the temperate regions of 
the northern hemisphere. C. coccinea is a Gulf 
States plant of some beauty, once known as gardo- 
quia. The low growing C. alpina with blue, and 
others with purple, red, yellow, and white flowers 
may often be made useful. Horminum Pyrenai- 
cum is also of the affinity. 
Salvia “sage” is a large genus of 450 or more 
species distributed over most warm temperate and 
sub tropical regions. About 30 are natives of the 
United States, mostly near the Mexican boundary. 
Several are shrubby and densely pubescent, among 
which the hardy South European S. argentea with 
white flowers is a useful plant. Many are well- 
known flowering plants which vary considerably, 
but there are two variegated foliaged forms of the 
common sage which might be oftener employed, 
One of these has beautiful purple leaves in tricolor 
shades, the other has leaves bordered with creamy 
yellow, and if the flowers are kept picked off they 
are equal to coleus in beauty and of course much 
hardier. S. Sessei is an arborescent Central Amer- 
ican plant with good foliage and orange-scarlet 
flowers hardy in Southern California. 
Monarda, “Bergamot” as it is called in some 
parts of Britain and the south and west, has nine 
species all North American. They are well known 
plants, some of them quite showy.

Azaleas.

Editor Park and Cemetery. 
Dear Sir — I can assure J. M. that my observations on 
Ghent azaleas and their adaptability for this locality is not a 
mere illusion, but is based upon practical experience covering 
a period of over ten years, and this under different situations 
and in prepared beds, some of them costing more than I could 
have bought a good building 1 it for. 
I have also noticed their behavior in places outside of Chi- 
cago. One thing is true, though, that with good care and pro- 
tection during the winter I have carried them along for five 
years. But, dear me, who would want such sickly looking 
plants in the garden as these were after the first two years? And 
getting worse until they finally gave up the ghost. Flowers 
there were none except in the first year, with a few scattering 
in the second, and by close observation a few could be discov- 
ered the third year. I can also assure Mr. J. M. that our 
hardy American varieties are not adapted to this locality, 
either, except in the hands of a crank like myself who is satis- 
fied so long as a green leaf can be seen. • J. J.
