length of a common needle, very strong and sharp, especially 

 in young long branches. In these they are often of the length 

 of one's finger. From the old branches and branchlets, how- 

 ever, they mostly disappear, so that they can be handled 

 without injury, and if the tree be carefully deprived of its 

 young long branches it can be easily climbed. The younger 

 trees for a long time are certainly not thicker than one's arm, 

 and everywhere, both on the trunk and on the branches, bear 

 sharp and horrid spines. The flowers are white, like the pre- 

 ceding, with five'petals, only they are a little larger. The fruits 

 are spherical, oblate at both ends, without tubercles, and every- 

 where covered with marked foveoli. The colour is dark 

 green till they become wholly ripe. If they remain on the 

 tree for a long time, often they turn yellow, or orange, on one 

 side, and some also colour all over ; but these then are already 

 over-ripe and spoilt. Their skin has a sulphurous odour, 

 but less so than the sweet oranges, and it is of the thickness 

 of about a thick quill. The pulp is divided into ten quarters, 

 and they are as firmly adherent to each other as to the skin, 

 so that they are not easily separated. This orange is, never- 

 theless, very juicy and mucilaginous, and as acid as the 

 Spanish sour orange (Seville), but not so pleasant, and rather 

 bitter. It has many seeds, oblong, rugose, and sinuous, with 

 a white and thick shell ; beneath that is a purplish pellicle, 

 and inside all is a whitish kernel. 



" The wood is whitish and sufficiently hard, but cannot be 

 much used for implements because it is very crooked. This 

 kind is more productive than any other species of lemon found 

 in these regions. It fruits all the year round, and can be 

 used daily. It grows in all soils, but above all, it prefers the 

 proximity of human habitations.* 



" In Latin it is called Aurantium acidum ; in Malay Lemon 

 Itam, that is black lemon (from its dark green colour) ; in 

 Banda Usse Mcttin ; in Amboyna Usse Metten. 



"It does not occur in all the islands of Maritime India. 

 Moreover, in Java, Baleya, and Celebes, this orange is 

 unknown. In Amboyna it is more plentiful, but in Ter- 

 nate and Banda it is rarely met with. Although these 

 oranges are full of juice, nevertheless they are rarely, or not 



* Presumably on account of the manure.
