56 THE BOTANY OF BERMUDA. 
The name immortalizes Quassi, a negro slave of Surinam, who made 
known the medicinal properties of one of the species. 
Ailanthus glandulosa, Desf. 
Originally from China. Introduced by Governor Elliott. The finest 
trees are at the public buildings, Hamilton. 
Xanthoxylum Clava-Herculis, Linn. 
A single tree of about 10 inches diameter on a hill east of Paynter’s 
vale. Easily known by the large pellucid points in the leaflets and 
their strongly aromatic taste. Although this tree was the object of 
numberless visits at all seasons, the writer could never find fruit or 
flower; nevertheless there are a few seedlings to be found among the 
Sage and Sponia bushes around. 
According to one tradition this tree, now 504 inches in girth, was planted 
about a century ago by a Mr. Paynter, and has not increased in size 
within memory; it does not however look an old tree. The writer in- 
clines to believe that it is a last survivor of the native ‘ yellow wood” 
frequently mentioned in the first accounts of the island.* Every en- 
deavor to transplant young plants failed, owing to the impossibility of 
extricating their long tap root unbroken from the crevices of the rocks. 
Citrus Limonum, Risso. 
The common wild lemon, berry ovoid, tubercled or rugulose; very 
acid; leaf-stalks with scarcely any trace of a winged margin. (C. spin- 
osissima, Rein.) 
Var: called Pumpnosed lemon. 
Var. with smooth skin of small size, 14 to 14 inches in diameter and 
nearly globular. C. limetta, Risso. 
Var. with smooth skin, of larger size, ovoid, called the Lisbon lemon. 
*<cThe timber of the country consisteth of three sorts; the one is the cedar; very fine 
timber to worke upon, of color redde, and verie sweete; the other sorts wee have noname 
for, for there is none in the company hath seen the like in other countries before wee 
came: some did thinke it to be lignum vite but it is not soe, it is a verie fine wood, of 
colour yellow, and it bears a leaf like unto a walnut tree, and the rine or barke is 
is much like a walnut tree, and the barke if one taste of it will bite one’s torigue as if it 
were Ginney Pepper. That wood also is very sweet.” 
This description applies closely to Xanthoxylum. Professor Oliver, writing from 
Kew in October, 1872, having only leaves before him, remarked: ‘‘The leaves, 
strongly translucently dotted, without flowers, must belong to a species of Xanthoxy- 
tum, and agree fairly with a flowerless Dominica specimen, which has been queried as 
X. aromaticum but the species must remain doubtful until we have flower and fruit, 
which we shall be particularly obliged for.” The visitor, therefore, who shall be so 
fortunate as to find the tree in flower, will help to solve a problem of unusual botan- 
ical interest.
