The species is very vigorous, half -trailing in habit, 
often forming clumps 15 feet high and 20 feet in spread. 
It is remarkable for its huge fruit-clusters and great 
productiveness. The fruits are blackberries of good 
size and quality. Plant breeders in Texas, who are 
using southern forms of blackberries, close to the 
dewberry group, should find it of interest. 
"Rubus urtieaefolius Poir. (R. triehomallus Schlecht.) 
S.P.I. Nos . 45356 , 49333 , 51354 . This interesting black- 
berry was obtained in northern Guatemala, at elevations 
between 3,000 and 4,000 feet, and also above Esperanza, 
Colombia, at elevations of 5,000 to 6,000 feet. It 
makes a large, nearly erect plant, with stout canes 
heavily clothed with reddish glandular hairs. The 
fruit-clusters are small, rarely over 5 or 6 inches 
long: they carry a large number of round, maroon- red 
berries scarcely half an inch in length. The seeds 
are so small and soft as not to be troublesome when 
the fruit is eaten, and the flavor is sweet and very 
pleasant. This plant is close to some of our southern 
dewberries, and might advantageously be crossed with 
them, to secure forms of erect habit and greater fruib- 
fulnegs, 
"Rubus tuerekheimii Ryd. S.P.I. No, 49147. Prom the 
vicinity of Guatemala City, Guatemala. A species close 
to R. adenotriehos in character, and like the latter, of 
interest to those breeding the southern forms of black- 
berries. The fruits are commonly sold in the markets 
of Guatemala City, 
"Rubus eriocarpus Liebm. " S.P, I . No. 51094. Prom the 
upper slopes of the volcano Irazu, in Costa Rica. This 
is one of the few true raspberries which are found in 
tropical America, and is of great interest because of 
the possibility that it will, when crossed with some 
of our northern raspberries, give rise to new. forms 
which will be suitable for cultivation in our south- 
ern states. It is a fruit much like R. glaueus in char- 
acter, but somewhat smaller. The plant also is smaller, 
"Rubus roseus Poir. S.P.I. Nos. 53186 and 53218, 
From the highlands of Ecuador. We have named this the 
'Tungurahua' raspberry. It is found upon the slopes 
of the volcano Tungurahua, up to elevations of about 
13,000 feet. The plant is half -trailing in habit, form- 
ing clumps 5 or 6 feet high; the fruits are an inch
