L. Morrowii rosea, Dippel, Handb. Laubholzk. 1 3 225 (1889). 
Like the preceding hybrid, this was raised from seed 
distributed by the botanic garden of St. Petersburg as L. 
Morrowiti and it is now not uncommon in cultivation (Ar- 
nold Arboretum, etc.). 
f. CANDIDA, f. ALBIDA, f. INCARNATA, f. ROSEA, and f. 
ATRO-ROSEA, Zabel, /. c., differ chiefly by the color of 
the flowers. 
Here may be inserted the following form originated 
from seed of L. Morrowii in the botanic garden at Muen- 
den; the other parent is probably a small-flowered form or 
a hybrid of L. Tatarica. — Sometimes cultivated (Arnold 
Arboretum, etc. ).
