224 CONTRIBUTIONS FROM THE NATIONAL, HERBARIUM. 



Pennisetum breve Noes 3 * of Brazil is very closely related to P. tetoswtn. Doell 

 reduces it to a variety of that. The type of this, collected by Martius in Bahia, was 

 examined by A. S. Hitchcock in the Munich Herbarium. It is not here included 

 because the plants are much smaller and the fascicles and spikelets are laiger. None 

 of this form is found among North American collections; our few specimens an; from 

 near Rio de Janeiro. Panicum alopecuros Lam. 39 (not PenniseLum alopecuros (Neee) 

 Steud. 1854), described from Brazil, the type of which, from Rio de Janeiro, was 

 examined by A. S. Hitchcock, in the Lamarck Herbarium in Paris, belongs to this 

 form.

 Garber 's original notes.
