400 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1926 
groves far down in the valley. It was a day of blue and silver, blue 
sky overhead, blue mountains in the distance, and silvery grasses all 
about me, Z’rachypogon, Andropogon, and the Ceresia group oi Pas- 
palum, with spikelets clothed with silvery hairs, characteristic of the 
high, open campos. Loveliest of them, Paspalum splendens, waved 
its pair of glittering silver banners above the other grasses. Even 
the best find of the day, Panicum arnacites, had silver spikelets, hung 
like pendants on hairlike pedicels. A striking tall species of Paepa- 
lanthus (probably P. speciosus) was common on the upper rugged 
slopes and also a little one growing on hummocks of its own mak- 
ing. <A terrestrial orchid with a single beautiful large pink flower 
and composites with purple, pink, or yellow heads dotted the campos. 
On a cliff by a little waterfall in a shady ravine I found plenty of 
the dainty little Raddia nana with filmy ferns and mosses. 
Karly the fourth day I took the road to Lagoa Santa, to be picked 
up by the caminhao when it overteok me. The collecting was so 
good that, though I hurried, I had gone only 10 kilometers when 
the caminhao appeared. The kindly driver stopped for me, how- 
ever, when I glimpsed some grass I wanted. 
On April 6 I left Bello Horizonte for Ouro Preto, the old capital 
of Minas, the “ Villa Rica” of Martius and other early travelers. 
Though only about 100 kilometers to the southwest the country was 
very different, being granite and red clay. One day in the Ouro 
Preto hills and the next by horse to Itacolumi, the high peak (1,752 
meters) to the southeast, where again I had a rich harvest on high 
open campos and rocky slopes, and then I left the Zona do Campo for 
Vigosa in the Zona da Matta. Dr. P. H. Rolts, formerly director of 
the Experiment Station at Gainesville, Fla., is building up a school 
of agriculture for the State of Minas Geraes at Vigosa. The country 
is much more fertile and more densely populated than the Bello 
Horizonte country. Here Ceiba and quaresma (Zibouchina sp.) 
were in bloom. JI had missed them in Serra do Curral and Serra 
de Cipo. I was fortunate here in being the guest of the Rolfs 
family. The swampy places and borders of the second growth 
forests (chaparao) that clothed the hills afforded good collecting. 
Two days were spent at Anna Florencia to the northeast, and then 
with Doctor Rolfs and his daughter I made a trip to Serra da 
Gramma, some 60 kilometers east of Vigosa, in the Serra Sebastiao. 
We stayed at a fazenda, two days’ journey on horseback from Sao 
Miguel, stopping over night, going and returning, at Araponga. 
(This musical name is that of the anvil bird of the region.) ‘The 
trail led through forested hills often hung with bamboos. We 
reached the fazenda in the middle of the afternoon and had time to 
botanize for a few hours. The third day we rode to the base of
