THE PAPAVER, BRASSICA, AND VIOLA ALLIANCE. 
There are 28 tribes, 328 genera, and 2697 
species in this alliance. Trees, shrubs, and herba- 
ceous plants are included, but in'the eastern United 
States they are limited to a herbaceous representa- 
tion, unless indeed Idesia polycarpa, a Japanese 
tree, prove prosperous south. There is a much 
similarity between poppies and plants of the pre- 
vious alliance, and even botanists rely a good deal 
on the milky juice of the poppies as a distinguish- 
ing character. 
Sarracenia, “side saddles,” as the English col- 
onists called the flowers, are all North American 
bog plants. Darlingtonia Calif ornica is very simi- 
lar to Sarracenia. 
Papavcr, the true poppies, 
have 26 species found over 
all the continent s and in Au- 
stralia — outside the Tropics. 
Their flowers are mostly bril- 
liant in color often large in 
size and very showy. Their 
juices are narcotic, some are 
the basis of opium and its 
products. There are beauti- 
ful magenta scarlet varieties 
grown on the mountains of 
India which I have not yet 
DARLINGTONIA CALiFOR- Seen ill gardens.' The orien- 
tal poppy is a brilliant garden 
ornament in North America; and sometimes on al- 
luviums, the annuals do well, but on sands they are 
very fugitive, and short lived. 
Meconopsis boasts 9 species principally in East- 
ern Europe, the Himalayas and Wastern North 
America. They are elegant plants with stalked, 
pinnate leaves, yellow juice, and yellow flowers in 
the European, and blue, lilac-purple, or rich 
yellow in the taller scarcer Himalayan ones. 
There are both perennial and annual .species. 
Bocconia has 3 species in China, Japan and Tropi- 
cal America. B. cordata is seen in gardens where it 
is used for its foliage. It is hardy, large spreading, 
and rather coarse. It is best planted where it can 
be mowed around in American gardens, and so in- 
deed are most plants of like character. 
Glancinni “horned poppies” have 9 species in 
Europe, Eastern Asia, and North Africa. They 
are annuals or biennials with handsome yellow, or- 
ange, red, violet and tri-colored flowers. On the 
East coast of England some of these plants live on 
the sea shore quite within the influence of the spray. 
They flower for a long time, but like most of the 
poppy tribe the individual flowers soon lose their 
petals. The common yellow horngd poppy 
SANGUINARIA CANADENSIS. 
lives several years near the coast, but inland 
must be treated as an annual or biennial. G. 
violaceum is one of the most fugitive of all, as the 
petals fall almost as soon as expanded. The scarlet 
horned poppy is an annual of great beauty, some- 
times found in England. 
Reenter ia has 2 or 3 species in Europe, West 
Asia and North Africa. 
Hiinneniannia, has i species in the United States 
and Mexico. 
Esehscholtzia has 15 species all from Western 
North America. E. Californica and its various 
colored forms are best known, E. tenuifolia has 
however been cultivated. Both are useful showy 
annuals. 
Dieentrahdi?, 13 species distributed over Central 
and Eastern Asia and North America. D. specta- 
bilis is the most familiar and beautiful of herba- 
ceous plants. There is a white variety, but not so 
good as the type. D. eximea, and D. chrysantha 
(the latter Californian) and some others are occas- 
ionally seen. Adlutnia is a native climber. 
Corydalis has 100 species distributed over the 
temperate portions of all the continents. They are 
very like Dicentra in structure. Some are fibrous 
ESCHSCHOLTZIA CALIFORNICA,
