Jamesonia scammanae A.F.Tryon, Contr. Gray Herb. View in CoL 191: 164, fig. 9. 1962.
Range: — Costa Rica; Colombia to Bolivia (CO, LP).
Ecology:— Uncommon; terrestrial in moist grasslands, often among rocks; 2000–3900 m.
Notes: —Blade apices thin, worm-like, glandular-pubescent; pinnae abaxially densely hairy, hairs often matted; pinnae adaxially glandular or crustose. Jamesonia imbricata (Sw.) Hook. & Grev. , from Venezuela to central Peru, may occur in Bolivia. It differs from J. scammanae in lacking worm-like, glandular blade apices, bearing instead appressed hairs at the apices. Of the three varieties of J. imbricata recognized by A. Tryon (1962), var. glutinosa (H.Karst.) A.F.Tryon has reddish to dark brown rhizome hairs that are the same color or darker than the rhizome surface, and truncate, equilateral pinna bases; it is the most likely variant in Bolivia.
