members of our party, Mr. John Turle and the author, went 
back to Apolo where we remained until September. On this 
second trip to the interior we went from La Paz to Sorata as 
before, but shortly after leaving that place, kept somewhat to 
the left of our first route and quite near to the Sorata River, 
passing through Tacacoma and Consata and striking the 
Mapiri-Apolo trail some fifteen miles from Mapiri at Achi- 
quiri. Reaching Apolo the second time June 20, we re- 
mained till near the middle of September, exploring the ad- 
jacent region, especially that about Atten to the southwest, 
and Santa Cruz, to the northward. September 13 we again 
started for La Paz going by way of the Mapiri-Sorata trail, 
over roads already essentially traversed. The altitudes given 
are largely estimates, to be considered as only approximately 
correct. In the arrangement of species I have followed 
Brotherus in Engler & Prantl. 
ANDREAEA STRIATA Mitt. 
Common at 4200 or 4500 meters in the vicinity of Sorata, 
also collected near Ingenio, Tolapampa and Tacacoma. 
This species seems to vary in much the same manner as 
A. petrophila. The tufts measure up to 4 cm. high, with 
leaves from very papillose to nearly smooth (1680 to 1685). 
TREMATODON REFLEXUS C. Miill.

fine fruit, April 26, Tuichi river. The collum may be dis- 
tinctly strumose at base or without struma (1852, 1853 and 
2855).

Below Pelichuco, 2600 meters, on rock, April 30, 1902 
(2827).
