Decumana, Linn. (C. Pomeldnus, Hort.). POMELO, 

 PUMELO, SHADDOCK, GRAPE-FRUIT, POMPELMOS, etc. Tree 



479. Citrus trifoliata. Natural size. 



small, 25-30 feet high: young shoots slightly pubescent, 

 finally becoming smooth: Ivs. large, ovate or ovate- 

 oblong, obtuse, frequently emarginate ; petiole broadly 

 winged: fls. large, white; stamens 16-24: fr. pale lemon- 

 yellow, or in some cases reddish or flesh colored, globose 

 or pyriform, very large, in hort. vars. reaching 6-7 in. in 

 diameter and weighing 8-12 Ibs.; rind smooth, thick, 

 very bitter; pulp pale yellow, in some reddish, sweet or 

 acid. Malayan and Polynesian Islands. Extensively 

 cultivated in India, Florida and California, and in most 

 tropical and subtropical countries. A. G. 11:717. Mn.9:47. 

 The Pomelo is an excellent dessert fruit, and is being 

 very extensively planted, particularly in Florida. The 

 majority of the horticultural varieties cultivated in 

 America have originated in Florida, though some valu- 

 able sorts have been introduced. The round-fruited 

 sorts, commonly called Pomelos or Grape-fruits, are the 

 most valuable commercially. The pear-shaped sorts, or 

 Shaddocks, are cultivated more as curiosities, and are 

 seldom found in the markets. Hound varieties Pomelos: 



Aurantium : Fr. late medium, size medium. Florida. 

 Josselyn: Fr. large, late medium, quality good; prolific. 

 Florida. Hart : Fr. late medium, large, of very good 

 quality. Florida. Marsh (Marsh's Seedless): Fr. with 

 very few seeds, said to be of good quality and prolific, 

 of recent origin. Florida. Pernambuco : Prolific : fr. 

 late, large: thorns short. South America. Royal: Fr. 

 small, early medium, only slightly bitter ; prolific. 

 Florida. Tresca : Pulp rose-colored, said to be of ex- 

 cellent quality. Bahama Islands. Triumph: Fr. small, 

 late medium, quality very good. Florida. Walter: Fr. 

 late medium, large, of recent origin. Florida. Pear- 

 shaped varieties Shaddocks : Blood: Fr. large ; pulp 

 reddish or flesh-colored, of fair quality. Mammoth : Fr. 

 very large, but practically worthless. "Forbidden 

 Fruit": Fr. small, orange-colored, of fair quality. The 

 so-called " Bell Grape-fruit " is probably identical with 

 this. 



Japdnica, Thunb. KUMQUAT, KIN-KAN, KIN-KITS, etc. 

 Fig. 481. Alow bush, with smooth, angular branches: 

 Ivs. small, linear-lanceolate, slightly serrate, pointed or 

 blunt, wedge-shaped at the base ; 

 petioles narrowly wing-margined: 

 fls. small, solitary or in clusters, in 

 the axils of the Ivs.; petals 5; sta- 

 mens about 20, filaments united: fr. 

 small, often only % of an in. in diam., 

 ovate, oblong or spherical, orange- 

 colored, 5-6-celled ; pulp sour; rind 

 sweet. Cochin China or China. Cul- 

 tivated extensively in Japan, Florida 

 and California. R. H. 1875, p. 209. 

 The following are the two cultivated 

 varieties commonly grown in the 

 United States : Marumi (Round Kum- 

 quat) : Fr. round, small, %-!% in. 

 in diam.: tree slightly thorny. Na- 

 gami (oval or oblong Kumquat) : Fr. 

 ovate or oblong, %-l in. in diam. and 

 l%-2 in. long : tree thornless. The 

 fruit of the Kumquat, as it is most 

 commonly called in America, is com- 

 ing to be much prized for preserving, 

 and is also used fresh to considerable extent, the 

 sweet rind, as well as the pulp, being eaten. Both 

 the round and the oval sorts have beautiful 

 dense, dark green foliage, and form excellent 

 orange trees of dwarf habit for pot culture. They 

 are commonly budded or grafted on trifoliata or 

 sweet orange stocks. 



Medica, Linn, (named for the country Media). Fig. 

 474. CITRON, in the broadest sense, including citron, 

 lemon and lime. Bush or small tree : young shoots 

 glabrous, mostly reddish or purplish, in some yellowish 

 green : Ivs. smooth, oblong, acute : fls. hermaphrodite 

 or frequently unisexual, 

 mostly reddish or tinged 

 with red without : fr. 

 spherical, ovate or oblong, 

 often mamillate at apex. 

 India. A very variable 

 species, much modified by 

 cultivation and apparently 

 mixed by hybridization, so 

 that it is almost impossi- 

 ble to determine the rela- 

 tionship of the different 

 forms. 



Var. genuina, Engler. 

 CITRON proper. Lvs. ob- A0n OMT 

 long, serrate or crenate ; 48 ,' rane 

 petiole short, wingless : wers. 

 fr. large, frequently 3-4 in. 

 in diam. and 6-7 in. long, 

 mostly ovate-oblong, mam- 

 illate ; rind very thick, 

 tender, aromatic, more or 



less rough and warted (rugose); pulp but slightly 

 developed, dry (lacking in juice), acid or sub-acid. 

 The Citron is cultivated to some extent in Florida and 

 California, but not so extensively as in Italy and the 

 Mediterranean region. All varieties are very tender,
