_Laurina_, a hybrid of _Coffea arabica_ with C. _mauritiana_, having small narrow leaves, stiff, dense branches, young leaves almost white, berry long and narrow, and beans narrow and oblong.
_Murta_, having small leaves, dense branches, beans as in the typical _Coffea arabica_, and the plant able to stand bitter cold.
_Menosperma_, a distinct type, with narrow leaves and bent-down branches resembling a willow, the berries seldom containing more than one seed.

This is a comparatively new species, discovered in the Tchad Lake district of West Africa in 1905. It is a small-beaned variety of _Coffea liberica_]
[Illustration: BRANCHES OF COFFEA EXCELSA GROWN AT THE LAMAO EXPERIMENT STATION, P.I.]
_Mokka_ (_Coffea Mokkæ_), having small leaves, dense foliage, small round berries, small round beans resembling split peas, and possessed of a stronger flavor than _Coffea arabica_.
_Purpurescens_, a red-leaved variety, comparable with the red-leaved hazel and copper beech, a little less productive than the _Coffea arabica_.
_Variegata_, having variegated leaves striped and spotted with white.
_Amarella_, having yellow berries, comparable with the white-fruited variety of the strawberry, raspberry, etc.
_Bullata_, having broad, curled leaves; stiff, thick, fragile branches, and round, fleshy berries containing a high percentage of empty beans.
_Angustifolia_, a narrow-leaved variety, with berries somewhat more oblong and, like the foregoing, a poor producer.
_Erecta_, a variety that is sturdier than the typical _arabica_, better suited to windy places, and having a production as in the common _arabica_.
_Maragogipe_, a well-defined variety with light green leaves having colored edges: berries large, broad, sometimes narrower in the middle; a light bearer, the whole crop sometimes being reduced to a couple of berries per tree.[96]

_Columnaris_, a vigorous variety, sometimes reaching a height of 25 feet, having leaves rounded at the base and rather broad, but a shy bearer, recommended for dry climates.
_Coffea arabica_ has a formidable rival in the species _stenophylla_. The flavor of this variety is pronounced by some as surpassing that of _arabica_. The great disadvantage of this plant is the fact that it requires so long a time before a yield of any value can be secured. Although the time required for the maturing of the crop is so long, when once the plantation begins to yield, the crop is as large as that of _Coffea arabica_, and occasionally somewhat larger. The leaves are smaller than any of the species described, and the flowers bear their parts in numbers varying from six to nine. The tree is a native of Sierra Leone, where it grows wild.
