 slightly pubescent beneath, and may be considered a transition to the following 

 variety.

 tus ad venas laxe et ad venulas sparse pilosis, petiolis glabrescentibus, 

 3-7 cm. longis. Sepala florum sterilium ovato-oblonga basi late 

 cuneata, 4-6 (-8) cm. longa et 2-3 (-4) cm. lata.

Differs from the type in its thinner, dentate or denticulate leaves, slightly pu- 

 bescent on the veins beneath or sometimes glabrous. In the No. 2563 which I 

 consider the type of this variety and also hi No. 4462 the leaves are sinuately 

 dentate, while in all the others they are merely denticulate.

 rotundatis v. late cuneatis, integris, 8-12 cm. longis et 3.5-7 cm.
