a) typica, foliis adultis petiolo passim rufescente excepto glaberrimis 
distinete reticulatis; pedunculo communi, ramisque inflorescentiae, peri- 
anthiis modice rufo-tomentellis, demum deglabratis.

puberulo), infra parcius tomentosis saepe indistincte reticulatis; pedunculo 
communi ramisque inflorescentiae, perianthiis diutius rufo-tomentellis.

minora, ambitu valde variabilia, v. elliptica v. oblongo-lanceolata v. obovata, 
basi cuneata v. rarius subrotunda, brevius v. brevissime in petiolum la-
