10g Hermann Wolff. — Umbelliferae-Apioideae-Ammineae heteroclitae. 



Nota i. Varietas ß. quoad involucelli phylla breviora longiorave umbellulas ± superantia 

 vel eis in statu fructifero subbreviora et folia ± dilatata et obtusa vel db angustata et acuminata 

 valde variat; formae intermediae inter varietates a. et ß. haud raro occurrunt. 



Nota 2. Specimina fere omnia in hortis botanicis culta et in herbariis sub nomine B. 

 glaiici vel B. semicompositi asservata ad varietatem ß. pertinent. 



Nota 3. Mihi valde dubium est an stirps in peninsula Istria crescat. Planta Pospicha- 

 liana (Fl. österr. Küstenl. II. (1899) 149) ad B. tenuissimum pertinere videtur. In herbario cl. 

 Tommasinii nunc Tergesti asservato, quod liberalitate cl. Marchesetti perscrutari potui, nulluni 

 specimen ad B. semicompositum pertinens obvium. In Herb. Mus. berol. specimina juvenilia in 

 Istria collecta asservantur, quorum schedulis nomen B. semicompositum inscriptum est; re vera 

 specim. ad B. aristatum Bartl. pertinent.
