8 BULLETIN 30, PORTO RICO EXPERIMENT STATION. 
In September, 1916, 60 young trees were set in the field, where, 
having been fertilized, they are making good growth. In general 
appearance they do not differ greatly from the Porto Rican. Bour- 
bon is an early variety, nearly half of the crop having been har- 
vested by the end of September. 
The reduction in weight from cherry to cleaned bean is greater 
for Bourbon than for Porto Rican (see Table 4), and the bean is 
smaller (see Table 3), both of which points are market disad- 
vantages. Bourbon may be mixed with Porto Rican in marketing. 
The production is given in Table 6. 
Pointed Bourbon. 
According to Lecomte, 13 Pointed Bourbon was discovered by Le- 
roy in Reunion, and its aroma is not so good as that of the oval-seed 
type of Bourbon, known in Reunion as " cafe du pays." Lecomte 
also states that this coffee is classified by some as C. laurina. 
Pointed Bourbon is mentioned by de Wildeman 16 as one of the two 
varieties of C. arabica grown in Reunion, where it is known as 
Cafe Leroy. It differs from Bourbon proper in tree, foliage, 
and fruit. 
The tree grows very slowly, 8-year-old trees at the station being 
about 6 feet high. Older, fully developed trees, however, are 8 to 
10 feet in height. In form, the tree is conical with a rather stiff, 
erect trunk. The primary lateral branches turn upward when 
young, the secondary laterals are numerous, and the internodes are 
short. Some of the internodes on the laterals may measure l'J 
inches, and the average internodal lengths for the whole branch 
may be only -J to f of an inch. The leaves are elliptical, tapering 
to an acute base and apex, and are three times as long as broad, 
representative specimens ranging from 2 to 3^ inches in length. 
The cherry is comparatively small, as many as 414 being counted 
in a liter. The bean is pointed in shape and should not be mixed 
with typical Arabian coffees for marketing since it differs from 
them in shape. The tree, being small, yields a small crop. In 1922 
8-year-old trees at the station yielded, on the average, 0.9 of a liter 
of cherries each. 
The variety is not recommended for planting. 
Brecta. 
The variety Erecta was received from the Botanic Gardens, 
Buitenzorg, Java. (PL II, fig. 2.) Dr. P. J. S. Cramer, of the 
Department of Agriculture, Dutch East Indies, in his correspond- 
ence with the experiment station, writes, regarding this coffee: 
C. erecta is found from time to time in our plantations of C. arabica typica. 
It is probably a mutation repeating itself. * * * I consider it well fit 
for spots exposed to heavy winds. Productivity, satisfactory; growth, some- 
what more vigorous than the type. Not planted on a commercial scale. 
In June, 1909, 236 small Erecta trees were transferred from the 
nursery to their permanent place in the field. During six years, 
beginning with 1911, the trees attained in height approximately
