acuminate, strongly many veined and very sharp-serrate, more or 
less silky hairy beneath: flowers solitary or in few flowered clus- 
ters an inch and a half across, white showy ; fruits erect, bright 
red, long thimble-shaped, usually about an inch high, very showy, 
edible. It sometimes occurs in double form and is then known 
as variety coronarius. 
(b) Shrubby, sometimes trailing, prickles recurved; leaflets 
5-3, elliptical-oblong, pointed, pubescent above, hoary-tomentose 
beneath, unequally serrate, primary veins approximate ; petiole 
long with the under side of the midrib prickly ; racemes compound, 
villous ; petals obovate, as long the calyx-segments ; fruit ovoid, 
twice as large as the calyx. Habitat, Jamaica, common in the 
mountains. 
The question of exterminating the same by means of insects 
is however a delicate one. The only insect that could come into 
consideration would have to be a strictly specific one ; to secure 
the same it would be implicitly necessary to study the conditions 
in Jamaica and to find if the same have specific enemies. And 
again only such could come into consideration that would attack 
the flowers, flower buds or canes of said species only. To intro- 
duce others than specific should be prohibited as they would at- 
tack other plants belonging to the Rosaccae or rose family like 
peach trees and others, nothing said of our native raspberries, one 
of which furnishes fodder for cattle. 
The raspberries have quite a number of enemies attacking either 
roots, buds, flowers or ripe fruits, as for example the raspberry 
beetle (Byturas toinenfosus Fab.), the raspberry fruit beetle 
(Byturus unicolor Say), who eats out blossom buds. The rasp- 
berry bud caterpillar (Lamphronia rubiella Bjerk.), whose larvae 
pupate in the flower buds and leaves. Carpophilus brachyptcrus, 
a beetle of small size found numerous in the fruits of raspberries 
who secrete themselves in the cavity of the berry about the recep- 
tacle. The most common enemy of the raspberries is a weevil 
{Anthonomus signatiis) who punctures the buds and feeds on the 
pollen within them. The flower in general is its first resort for 
food. 
As stated before all these insects would unquestionably attack- 
other members of the rose family and perhaps also the flowers 
of other fruit trees and therefore would not be recommendable for 
importation.
