Trichodium nanum Presl, Rel. Haenk., I, 243. 1830. „Hab. in Peruvia ?“ 
Presls type specimen of Trichodium nanum is at Prague. It is the same 
as figured by Scribner, Ann. Rep. Mo. Bot. Gard., X, 54, 58, pl. 34, fig. 
2, 3. 1899. A discussion of the identity of our plant with Presl's is 
given in U. S. Dept. Agr., Div. Agros., Circ. XXX, 2, 1901. 
A. nana Kunth, Enum., I, 226. 1833. ,Peruviae?“ Transfers Tricho- 
dium nanum and gives a description. 
According to the strict application of the rules of priority, a new 
name must be given to this plant on account of A, nana Delarbre, Fl. 
Anverg., Ed. 2, 1800. This is a form of A. alba and seems not to have 
been taken up by later authors. 
Distribution: California to Peru.
