rarely almost glabrous; anthers oblong to oval; fruits con- 
nate or distinct, scarlet or black; seeds 2—4 mm., rarely to 
6 mm. long, granulose, brown. The first three species of

red fruits and their pubescence a closer relation to the 
Alpigenae than the rest of the group, which are all black- 
fruited except ZL. Chamissoi. 
A. Ovaries wholly or partly connate; bractlets in two separate pairs. 
B. Fruit red; peduncles long and slender; corolla usually dark 
purple.

pubescent beneath. 77. L. Tatarinovii, Maxim,
