The distinctly hexastichous forma hexasticha, which Urban, under 
Phoradendrum, (Bot. Jahrb. vol. 23. Beibl. 57. p. 3. 1897) bases upon 
Viscum cornifolium Presl (Pl. 222), is further represented from Mexico 
(Smith, 263), and finds a counterpart in certain Ecuadorean specimens 
(Sodiro, 1872, 1874, 148/28). Ule’s no. 4800, from about Rio de J aneiro, 
presents the exceptional phenomenon in the genus of somewhat branched 
spikes in some cases, and may be known as f. composita.
