boliviensis Mont. Fl. Boliv. p. 20 (non Greville)" appears in the 
synonymy of P. curta as given by De-Toni (Syll. Alg. 4: 959) but 
the name does not appear in the place cited and we do not find 
that it was ever published except thus by De-Toni.

АП of the first four specific names cited above were e | 
applied to plants collected оп Ше coast of Peru and we adopt for. 
the present Falkenberg's opinion that they apply to forms ofa. 
single variable species. Some of Dr. Coker's specimens (58 
one of the four under 465) are near Montagne's type except "| 
being smaller; the others are close to Kützing's Bartlingiana ай 
spinifera. Тһе typical form and spinifera occur together um 
по. 465 and are strikingly different in habit, but the Bartlingia?
