Beilis “The Daisy” has 8 or 9 species in the 
northern hemisphere. B. perennis the British daisy 
so beautifully sung 
by Burns is often ill 
at ease in Atlantic 
States. I have known 
it naturalize on lawns 
in the lake regions 
however, and it is 
said to do well in 
southern California, 
which is another of 
the remarkable 
things we hear of 
that wonderful clim- 
ate. B. integrifolia is a native from Kentucky 
southward to Texas. B. rotundifolia var. ccerules- 
cens is the blue African daisy. B. sylvestris is a 
white flowered Mediterranean kind. Why not get 
the species together and try to hybridise them? 
Boltonia has 12 species from northern and sub- 
tropical Asia and North America. A few are in 
gardens. 
Callistcphus , “China Aster,” is a well-known 
monotypic plant of great beauty in its original form, 
found in Asiatic countries, and immensely varied 
and doubled in cultivation. 
Aster “Michelmas Aster,” has between 250 and 
350 species and forms distributed over America, 
Asia, Africa and Europe. The genus now includes 
a good many plants formerly known as Chrysocoma, 
Lynosyris, Bellidiastrum, etc. A. Palmeri is a 
shrubby species of 3 or 4 feet high found in south- 
ern Texas. A. ptarmicoides var. lutescens has pale 
yellow rays. A. lynosyris is the English “goldy- 
locks,’’ or one of them! A good deal of attention 
is given these plants in Europe and deservedly. 
They are mostly among the last flowers of a season, 
and are in handsome shades of whitish or purple. 
Olearia is the popular “musk tree” genus. They 
are trees and shrubs in about 85 species from Aus- 
tralia and neighboring islands; several are cultiva- 
ted on the mountains of India, Algeria, the south 
of England, Southern California, and similar nearly 
frostless climates. O. argophylla has beautiful 
wood with a twisted and figured grain, a good deal 
used by the Colonial cabinet-makers. 
Commidendron and Melauodendron are I suppose 
some of the St. Helena trees of the tribe, but I have 
never met with them in cultivation. 
Cclmesia in 25 species are lanate herbs or sub- 
shrubs from Australia and New Zealand. They have 
handsome purple or white daisy like flowers; but 
olearia lyalli. — Gardener's Chronicle. 
their seeds have proven difficult to germinate and 
probably soon lose vitality. 
Erigeron is a large genus of 1 10 species, Amer- 
ican largely, but with species distributed over the 
temperate and cold regions of the old world. Per- 
haps a couple of dozen are known in the best bo- 
tanic gardens. 
Microglossa has 8 species in Asia and Africa. 
Several are shrubby and the Himalayan M. albes- 
cens, is sold as Aster cabulicus in European nur- 
series. 
Chrysocoma has 8 species of low growing frutes- 
cent evergreens from South Africa with white or 
yellow flowers. 
Baccharis is a large genus of shrubs or herbs all 
North or South American. B. halimifolia a species 
of the Atlantic coast lands is one of two or three 
woody plants of the Alliance known to northern 
gardens. The small yellowish white flowers are in- 
conspicuous and dioecious, and the fertile plants are 
alone worth growing for their abundant silvery pap- 
pus to which the plants owe their name of “ground- 
sel trees.” B. salicina and B. angustifolia ar e 
woody kinds from the south and southwest, and 
several are found through the arid rigions westward
