 islands. It is an evergreen tree ten to twenty 

 feet iiigh witii oblong pointed leaves hoarj- 

 beneath, giving in the wind a silvery appear- 

 ance Its flowers are whitish, but no notice 

 has been taken of its fruit, and the tree has 

 reverted to a wild condition. 



Manqrove (Rhi/.opora Mangle)— An ever- 

 green tree, ''•ontinually throwing out from its 

 branches rootlets which penetrate the luud 

 or swamp soil, forming new trunks, and 

 creating thereby dense thickets. It is fre-

 iiia Nitida) distinguishable from the true 

 Mnngrove by its dusty white appearance, tlie 

 underside of its leaves being covered with a 

 white pubescence. 



The Buttercup (llanunculus Parvillorus) 

 with its yellow flower is too well known to 

 need description. From its universality there 

 is every reason to consider it as indigenous. 

 It has two congeners— (R. repens) with long 

 runners, and (R. Muricatus) more abundant 

 in damp than in dry ground. Its stem is 

 erect and stronger than the other species. 



The. Stinging Thistle (Argemone Mexicana) 

 is doubtless indigenous. It grows everywhere, 

 its yellow flowers making it very conspicu-

 half-clasp the stem, and the flower stalks 

 glow out of the axils of the leaves. 



Thd Stock (Matthiola Incana) growing along 

 the seashore bears handsome purple flowers 

 one to two inches. It is grown in gardens, 

 but this plant is not an "escape", the wild 

 plant itself being evidently a native, from 

 which the garden varieties have been pro- 

 duced.
