Hieracium purkynei Čelak.

Purkyn’s Hawkweed (Hieracium purkynei)  

Purkyn’s Hawkweed is one of about 23 endemic plant species that are restricted to the Krkonoše Mountains, a mountain range located in the north of the Czech Republic and the southwest of Poland; this species occurred only at the Czech side of the border.

The species was a member of the Eginenthal Hawkweed aggregate (Hieracium gombense Lagg. ex Christen. agg.) (see photo).

Hieracium sprucei Arv.-Touv.

Spruce’s Hawkweed (Hieracium sprucei)  

Spruce’s Hawkweed is known only from a single collection made somewhere in Ecuador in the 1880s, which, however lacks any information about the exact collection locality.  

The species may now be extinct, but this claim has to be resolved yet.
