interlacing boughs of the willow. Some of the other ranchos 
which I saw had their sides made of sod. 
A stream called the Arroya de Canelones ran through the 
estate. Like most of the streams of the regions, its channel was 
very crooked, owing to the flatness of the country. Its margins 
were bordered by several species of water-plants: Pontederias, 
Potamogetons and Typhas, and in places I saw some Lemna 
floating. On the banks grew the beautiful Sa/ix Humboldtiana, 
Willd., covered with a mass of yellow catkins; Ce/tzs tala, Walp. 
(nom. vulg., ‘‘tala”), a small thorny tree with smooth white 
bark, belonging to the same genus as our hackberry; Lucuma 
Sellowit, Alph. DC. (called “ mata-ojo,” or eye-bane), one of 
the Sapotacez, not yet in bloom, with leaves like those of the 
Oleander; a small tree called “ Molle” (Duvana dependens, 
DC.), with inconspicuous flowers, just beginning to open, and 
with its branches covered with galls; and a beautiful fragrant 
yellow Acacia (A. Farnesiana, Willd.) called ‘‘ espintllo,” or 
‘aroma,’ by the natives. This was in full bloom. I gathered 
a quantity of its blossoms to pack away with clothing in my 
lockers on board ship. Climbing among its branches was a beau- 
tiful Solanum (S. boerhaviefolium, Sendt.), with clusters of large 
pale lavender flowers. I afterwards found this vine in barberry 
thickets (Berberis laurina, Billb.), and with it a bright crimson 
Tropeolum (T. pentaphyllum, Lam.), with elegant nodding tubu- 
lar flowers and delicate five-parted Jeaves. The effect of the yel- 
low blossoms of the barberry combined with the delicate lavender 
and the crimson of the climbing vines, was exquisite. 
Farther up the stream I collected //ex dumosa, Reiss., and 
several species of Euphorbiacez, among which were Phy/lanthus 
Sellowianus, J. Miiller, and two species of Sebastiana, called by 
the natives “ blanquillo.” All of these were scrubby trees or 
shrubs. I also collected in the montes, or copses, along the 
stream, Schmidelia edulis, St. Hil., which is said to bear small 
edible berries, and Oveodaphne acutifolia, Nees., called ‘‘ white 
laurel” by the natives from its dark, shining leaves. This, I 
think, completes the list of the trees of the region which I ob- 
served, though I heard of several others which I did not see, 
among which were two or three species of palms.
