BULLETIN 71, HAWAII EXPERIMENT STATION 



Gehring 



The original tree of the Gehring was a seedling grown by 

 H. A. Gehring, 809 Kinau Street, Honolulu. The station began 

 the vegetative propagation of the tree as a variety in 1921. The 

 original tree was known as a shaddock, and the variety was re- 

 corded as accession No. 4545, and commonly designated as sweet 

 shaddock. Other more or less sweet-fruited seedling shaddocks 

 began to appear and the variety was called the Gehring. Because 

 the fruit lacks coarseness and bitter tang, characters commonly 

 determining most shaddocks in Hawaii, the Gehring is here 

 described as of the pomelo strain. 



Fruit — Form, globose, 6^ to 8 inches in diameter ; surface, slightly rough or bumpy, 

 greenish yellow ; rind, % to % inch thick ; fruit sections, 15 to 19 ; pulp, yellowish green ; 

 sacs, numerous, slim, usually adhering ; juicy seeds comparatively small, few to many 

 varying with the season. The Gehring is an excellent breakfast fruit. 



Carter 



The original tree of the Carter was a seedling grown by the 

 late Geo. R. Carter, Liliha Street, Honolulu. From graft wood, 

 obtained by the station in September, 1922, fairly vigorous trees 

 have been grown, but they are rarely prolific. The young twigs 

 have a slight silvery pubescence. 



Fruit — Size, large ; diameter, 7 to 9 inches ; form, globate or globose ; surface, greenish 

 yellow to yellow, comparatively smooth ; rind, % to % inch thick ; fruit sections, 12 to 16 ; 

 pulp sacs, broadly spindle shaped, coarse, separating freely, and yellow ; flavor, slightly 

 bitter, but pleasing. The seeds vary from few to many. 



Bitter 



Trees of this seedling variety are large and prolific. The 

 foliage is coarse and dark green. Although ornamental, the 

 fruit is too bitter to be eaten, but the seeds are often used in pro- 

 ducing rootstocks on which to graft other varieties of citrus. 



Fruit — Size, large 5 to 7 inches in diameter ; form, spherical ; surface smooth, greenish 

 yellow ; rind, comparatively thin ; seedy ; pulp sacs, large, yellowish ; juice, very bitter. 



Tantalus 



The original tree, apparently a seedling, is growing at the 

 Tantalus substation. It is not known from where the plant was 

 obtained or when it was planted. It is known, however, to be 

 over 30 years old. In comparison with other shaddocks, it is 

 small, has a round dense top and dark green foliage. Although 

 it is not considered prolific, it usually has a fair crop of fruit. 



Fruit — Size, large; form, oblate, about 6 inches in diameter; surface, rough, light green, 

 studded with numerous large oil glands ; stigmatic portion depressed often in the narrow 

 slot about an inch long ; pulp cells large, rather dry and rather bitter ; numerous seeds. 



Pyriform or Chinese 



This variety is grown for its fruit which is used for its dec- 

 orative effect and as a holiday delicacy. The true variety has 

 been propagated vegetatively by air-layering for possibly a cen- 

 tury. The fruit of seedlings tends to be more or less of a bitter 

 flavor. 



Fruit — Size, large ; form, oblate to pyriform, 6 to 8 inches in diameter ; surface greenish 

 yellow, quite rough, and containing numerous large oil glands ; rind, thick and spongy ; 

 pulp sacs, large, moderately juicy and of mild flavor ; seeds varying from few to many. 



Kohala 



Possibly a variety originating as a seedling in Kohala, Ha-
