Leaves oblong-lanceolate, acuminate, gradually narrowed and rounded at the base, three-nerved, 

 entire, undulate and slightly thickened on the revolute margins, dark green on the upper surface, 

 paler on the lower surface, from 8 to 12 centimetres long and from 2.5 to 4.5 centimetres broad, 

 their petioles stout, from 2 to 2.5 centimetres in length. Flowers 2 centimetres in diameter, short- 

 pediceled, in open cymose panicles ; calyx urceolate, four- or five-lobed, the lobes nearly obsolete ; 

 petals four or five, oblong-obovate, reflexed after anthesis, white ; ovary three-celled ; style sur- 

 rounded at the base by a short sheath ten-toothed at the apex. 1 Fruit oblong to ovate, conspicu- 

 ously constricted at the apex, from 6 to 8 millimetres long and from 4 to 5 millimetres in diameter. 



In Florida a shrub or in the dense woods of the keys of the Everglades a slender tree, often 

 10 metres high, with an erect trunk from 6 to 7 centimetres in diameter, covered with thin light 

 gray-brown slightly fissured bark, small spreading branches becoming erect toward their apex, 

 and gracefully drooping leaves ; or in the sandy soil of open pine woods a shrub, often less than 

 1 metre in height. Flowers from March to May. Fruit ripens late in the autumn or in the early 

 winter. 2

1 This peculiar sheath was noticed by A. Richard, who described and figured it as one of the characters of his genus Naudinia, 

 suggesting that it might be an epigynous disk, but by later authors it has been overlooked. We are unable to find the long setse 

 ending the lobes of this sheath as figured by A. Richard. 



2 Tetrazygia Ucolor appears to have been first noticed in Florida by Messrs. J. J. Carter and J. K. Small, who found it in the 

 pine woods eight miles southwest of Cutler, Dade County, in November, 1903. Later it was found by the botanists of the New 

 York Botanic Garden near Camp Longview and on Long Key in the Everglades (see Small, Bull. N. Y. Bot. Gard. iii. 431). 



8 According to Triana (Trans. Linn. Soc. xxviii. 103), Melastoma foliis lanceolatis: nervis tribus longitudinalibus : subtus glabris 

 coloratis, Linnaeus, Hort. Cliff. 162, is the first description of this species.
