" Now we shall narrate of the Lemon cohort, which occur 

 in these aqueous portions of the East Indies ; and, at the 

 same time, we shall demonstrate whether and how they differ 

 from those in Europe. First comes before us the largest 

 species of all, the Pomum Assyrium, by the French called 

 Pom-sires, which, on account of its size, we have named 

 Decumanum (huge). Of this we observed four species. 

 The first has not a tall trunk, but is thicker than in other 

 lemon trees,* although its branches are more slender ; and, 

 therefore, as it produces larger fruit, they are often propped 

 up. Its leaves have the common character of all lemon 

 trees. Their inferior part, however, is cordate,t as if there 

 another leaf had grown. All leaves, at their insertion, have 

 a spine. Those, however, of adult and young trees differ. 

 In the latter the leaves are more than 7 inches long ; their in- 

 ferior cordate part is 2 inches, and the superior partif about as 

 broad as the hand ; at the edges, almost entire, smooth, and not 

 serrate. If these young trees, however, are situated in shady 

 places, their leaves become a span long, and their width 

 that of six fingers' breadth ; and their cordate part has a 

 width and length of three fingers' breadth. The leaflet is 

 rounded at the tip, and emarginate. To every leaf there is 

 a spine, as long as the thumb-joint. The older these trees 

 are, the less spines they have. In adult trees, the leaves 

 are 5, 6, and sometimes 7 inches long, but their cordate 

 parts are smaller and narrower, about the length of one inch, 

 and half a finger's breadth ; and in all, certainly as wide as 

 a whole finger's breadth. They are divided by parallel 

 nerves, which in young leaves are prominent below, and in 

 adult leaves above. The old leaves become yellowish be- 

 neath, and are downy. As the tree grows older, it has almost 

 no spines, or sometimes slender and short ones, and then 

 only on the young branches. 



" The flowers are racemose, and in large white heads, with
