magna, plusquam 30-flora : involucrum multiseriale. Mexico, Mendez ! Beechey ! Coulter ! (No. 237, 

 Bolanos.) — CouIter's plant agrees with the speclmens described by De Candolle, havlng subpetloled 

 leaves ; but the plant gathered In Beechey's voyage has the leaves sessile by a subcordate base. There is 

 no further difference. In all of them the white wool disappears from the upper surface. 



7. B. RETicuLATA, DC. Mcxico, Hcenke. — This I have barely seen in the herbarium of De Candolle. 

 It is possibly the same as the next, which, however, has narrow serrated leaves, and naked inflorescence.
