6 MR. SPRUCE'S VOYAGE 
of an hour's walk from Esmeralda that I can scarcely credit its not 
being among Humboldt's plants. Another shrub or small tree growing 
along with it in great quantity is a stunted form of Humirium fiori- 
bundum ; the same widely distributed species accompanies the Com- 
mianthus near the Barra. Equally frequent was a Remijia with densely 
pilose capsules, shorter than usual in the genus; I was surprised to 
meet afterwards the same species on a small granitic mountain by the 
Pacimoni, especially as none of the plants accompanying it in the latter 
locality were identical with those of Esmeralda. Other shrubs were a 
Byrsonima, apparently a form of B. spicata, a Guatteria, a Pagamea, 
etc. Under large stones grew the most delicate little Fern I have ever 
gathered, looking at first glance like miniature Adlosorus crispus, but in 
reality more allied to Schizea; and along with it a small Grass with 
broad truncato-cuneate leaves, which I had gathered abundantly in 
similar situations by the cataracts of the Rio Uaupés. Rooting into 
clefts of the rocks, and twining on adjacent shrubs or over the rocks 
themselves, grew an Asclepiadea with narrow leaves and minute white 
flowers, looking not unlike Galium saxatile. In moist rocky places I 
found a shrub of about four feet high, with long pinnate branches, 
minute rigid leaves ending in an arista, and solitary axillary fruits the 
size and colour of haws. It is quite new to me, and seems to bea 
 eapsular Myrtacea, but I have not examined it closely. There were 
also a few Melastomacee and other things. 
'The savannahs near the pueblo were mostly dried up by the heat. 
The Grasses showed only withered culms, but I recognized among them 
several species I had gathered on the campos of Santarem and the 
Barra, including species of Paspalum, Setaria, Andropogon, Tricho- 
pogon, etc. I crossed the two first savannahs in the direction of 
= Duida, but found scarcely anything in flower. It is curious that on the 
second of these the only tree besides the Moriche Palm is a Qualea, 
which seems to me identical with one gathered on a low campo of quite 
similar character opposite the Barra, and which Mr. Bentham has 
 ealled Q. retusa. The tree at Esmeralda had neither flower nor fruit ; 
and if it was in the same state at the period of Humboldt's visit, 
most probably he did not gather specimens. 
x On a savannah which extends towards the Guapo there were still 
some moist places left, and in them,l gathered several interesting 
: little plants. They include two Burmanniacee (perhaps true Bur-
