The greenish agrumc, called by Rumphius : 

 Union -rentricosus, has characteristics peculiarly 

 its own, making it to differ essentially from our ; 

 agrumi. Its leaf seems as though cut in the mid- ; 

 die, it has so large a wing. Its flower, extremely | 

 small, has but four petals, and grows only at the 

 very end of the bough, in form of a bunch of 

 grapes. 



The fruit is nearly green, just a little shaded 

 with yellow ; its skfn, which is odorous, is cov- 

 ered at regular intervals by small buttons, all of j 

 one shape and size. Its pulp is granulous, green, 

 and very sour. There is nothing said of its 

 sexual system. We may connect to this species 

 the Umon tuberosus, the lemon curamus, the lemon 

 ayrestis or papeda, the limo ferus or swanr/i, that 

 Rumphius found at Amboyna, and which have 

 very nearly the same characteristics.

The dwarf agrume of Japan has been consid- 

 ered by Windelnow as a species of Citrus, but 

 the description of it by Thurnberg in his Flora Ja- 

 ponica, presents traits making it to differ from 

 European oranges. 



The most marked and at the same time most 

 singular points of difference, are the angulous 

 stem and axillary flowers. These traits would 

 seem to place it near the lemons of Amboyna 

 which so closely resemble the limonia and the 

 bilacus. Thumberg also says that the Citrus ja- 

 ponica, which, in the parts of fructification, offers 

 the same traits as the European Citrus, differs 

 notwithstanding, in its shrub-like form which it 

 always takes, in the smallness of its fruit, and in 

 many other ways. He adds that it can scarcely 

 be ranked in the class of oranges, its flowers be- 

 ing axillary, solitary, or binate, and never in bou- 

 quets ; that it is like the lemon in axillary thorns, 

 yet differs from it by the winged petiole, and by 

 the fruit, which has the shape and color of an or- 

 ange. 



The Citrus japonica is, perhaps, the same as 

 the aurantium pumilum madurense, or the lemon 

 twassi, and lemon colte, that Rumphius calls species^ 

 limonum fructu dulci omnium minima cortice lenui 



nee amaro. 



It has also some likeness 



to the Citrus margarita of Loureiro. 



It would be necessary, however, to examine 

 them in Nature, in order to see all their affinities. 



VARIETIES NO. IX.

The agrume of Madura is an extraordinary 

 bush, appearing to hold to the Cftnis and the 

 bilacus. Perhaps it is one of the links attaching 



these two genera, or il may be a product of their 

 mingling. The stem is not more than two feet 

 high; the branches, having no thorn, are augu- 

 lous, crowded, and striped ; the simple and soli- 

 tary leaf is but an inch in length. Its fruit is a 

 slightly flattened spheroid, always green, and the 

 size of a bullet. It is covered by a thin skin, like 

 a pellicle. 



This trait it has in common with many other 

 species, especially the l-imoneUus aurarim. En- 

 closed within this skin are numerous sections, 

 containing an aromatic, sourish pulp, and one 

 seed, always small and always solitaiy. 



Rumphius says nothing of its organs of repro- 

 duction. 



Loureiro, who gives a description of it under 

 the name of Cttnta madurensis, or Citrus inermix, 

 ramis diffusis, anyulatis, ywtiolis linearibus, fructu 

 globoso Iwvi, says its flowers are white, five-pe- 

 talled, small, and odorous, and united in small 

 number iipon one peduncle or footstalk. lie 

 says nothing of the number or position of its sta- 

 mens ; but as he places this in the genus (Mrtis, 

 we may presume that it is also of the class Poly 

 adelphia, order Icosandria.

Agrume Nipi^. 



Limonellus : Lemon Nipi^. (Riimph.) 



The agrume nipis appears to represent both 

 the orange and the lemon, yet differs by many 

 traits wholly its own. 



Its stem is very small, its branches end in a 

 sharp point like a thorn, its leaf is winged. The 

 flowers, axillary and solitary, are entirely white 

 and odorous. The fruit, yellowish like a lemon, 

 has the size and shape of an apricot, but is termi- 

 nated by a nipple very much elongated, and sin- 

 gularly pointed ; its skin, which is very thin, has 

 a pleasant odor, and covers a white pulp full of 

 acid juice. 



John Burman, in his Thesaurus Zeylawicus, re- 

 gards the Umon nipis as the same plant as the 

 limonia mains sylvestris zcykmica fructu pumilo, 

 of Ceylon. lie writes as synonymous the mains 

 aurantia fructu limonis pusillo acidissimo, of 

 Sloane, and the catu-isieru nareyam of Malabar, 

 of lleede ; which is the limonia acidissima of Lin- 

 nams. 



Nicholas Burman, in the Flora indica (which 

 he arranged according to the system of Linnspus), 

 in connecting to the citron lemon the limonia 

 innlm tyheslris zeylanica, of the Thesaurus zeylan- 

 icus of' Burman, regards it also as one with the 

 lemons of Amboyna, of Rumphius, (Umonellus 

 cum varietatibus. Ru MPII .) 



It is easy to see by examining the descriptions 

 and figures of these plants that they differ too 

 much among themselves to be considered a sin- 

 gle species. They really have some analogy con - 

 necting them, but even these likenesses cannot 

 make them rank in the same genus.
