VAK. 3. acida; leaflet elliptic-oblong, petiole many-times shorter than the leaflet 

 linear or obovate, racemes short, flowers small, petals usually 4, fruit usually -small 

 globose or ovoid, with a thick or thin rind, pulp pale sharply acid. Brandis, I.e. 52. 

 C. acida, Roxb. FL Ind. iii. 390 (who includes under this the varieties, if not species, 

 of Sour Limes ajid Lemons found in India). The large fruited states of this appear to 

 assume the form of the Citron, and the small to approach the W. Indian Lirae, 

 which is, however, described as a bush with white flowers. The Sour Lime of India. 



VAR. 4. Limetta ; leaves and flowers as in var. acida, fruit globose 3-5 in. diam., 

 rind thin smooth, juice abundant sweet not aromatic, Brandis, I.e. 52. C. Aurantium 

 vars. Limetta and Lumia, W. & A. Prodr. 98. C. Limetta, Risso ; Dalz. & Gibs. 

 Bomb. Fl. Suppl. 13 ; Wight Ic. t. 958; Walt. Cat. 6385. This includes 2 of Wight 

 & Arnott's varieties, viz., (1) C. Limetta, Eisso (Sweet Lime), with winged or margined 

 petioles, small white flowers, globose or ovoid mamillate fruit, and a rind with concave 

 vesicles. C. Limetta, DC. ; Wall. Cat. 6385. C. Limonellus, Wall. Cat. 6386 ? (2) 

 C. Lumia, Risso (Sweet Lemon), with a simply margined petiole, flowers tinged with 

 red, ovoid-oblong fruit with a long mamilla, and rind with convex vesicles. Wight 

 says that his C. Limetta is certainly indigenous at Kolagbery in the Nilghiris. The 

 Sweet Lime of India. 



2. C. Aurantium, Linn.; arboreous rarely shrubby, young shoots 

 glabrous greenish white, leaflet elliptic or ovate acute obtuse or acumi- 

 nate, petiole often broadly winged, flowers pure white bisexual, fruit globose 

 generally oblate not mamillate. 



Hot valleys along the foot of the HIMALAYA, from Garwhal eastwards to Sikkim, and 

 in the KHASIA MTS. 



A small slender tree, flowering in the rains, and fruiting after them, growing where 

 I have found it in the very bottoms of valleys, and where it did not occur to me to doubt 

 its being indigenous. The fruit was somewhat flattened or nearly globose, about 2 in. 

 diam. , high coloured, and uneatable, being (if I remember aright) mawkish and bitter. 

 The following are the principal cultivated varieties : 



VAR. 1. Aurantium proper ; petiole naked or winged, pulp sweet yellow rarely red. 

 Brandis, For. Fl. 53. C. Aurantium, L.; Roxb. Fl. Ind. iii. 392 ; W. & A. Prodr., 

 97 ; Wall. Cat. 6390 ; Dalz. & Gibs. Bomb. Fl. Suppl. 12. The Sweet Orange. 



VAR. 2. Bigaradia; petiole usually winged, flowers larger and more strongly scented, 

 rind very aromatic, pulp bitter. JBrandis, I.e. 53. C. vulgaris, Risso; W.&A.Prodr. 

 97 ; Wall. Cat. 6384 ; Wt. Ic. t. 957. C. buxifolia, Pom Wight & Arnott describe 

 its oil vesicles as concave, in contradistinction to C. Aurantium, in which they are 

 convex. This variety does not seem to be cultivated in India, except in gardens. 

 The Bitter or Seville Orange. 



VAR. 3. Bergamia ; flowers small very 'sweet-scented, fruit globose or pyriform, 

 rind smooth pale-yellow, pulp acidulous with pleasant aroma. Brandis, I.e. 54. C. 

 Aurantium, var. Bergamia, W. & A. Prodr. 98. C. Limetta var., DC. Prodr. i. 539. 

 Earely cultivated in India. The Bergamotte Orange. 



3. C. Kystrix, DC. Prodr. i. 539 ; young shoots glabrous, leaflet ovate 

 elliptic or lanceolate equalling or smaller than the very broad petiole, 

 flowers small white, fruit globose or obovoid. Kurz in Journ. As. iSoc.
