 deeply impressed on the upper side and pale on the lower side, and six to nine pairs of slender 

 primary veins connected by thin reticulate veinlets ; petioles slender, from 1 to 2 centimetres in 

 length ; stipules minute, whitish (on dried specimens) persistent. Flowers on slender pedicels from 

 3 to 6 millimetres long, in the axils of minute acute scarious deciduous bractlets, in crowded 

 clusters, the staminate one- to three-flowered on short peduncles, the pistillate one-flowered ; 

 calyx from 1.5 to 2 millimetres in diameter, four-lobed, the lobes triangular, suberect, about as 

 long as the tube, imbricated in the bud ; corolla rotate, greenish white, from 2 to 2.5 millimetres 

 in diameter ; petals four, ovate or slightly obovate in the pistillate flower, imbricated in the bud ; 

 stamens four in the staminate flower, nearly as long as the petals ; filaments slender, about as long 

 as the oval introrse anthers attached on the back near the base and opening longitudinally ; in the 

 pistillate flower much smaller and abortive; ovary four-celled, ellipsoidal; stigma small, discoid, 

 obscurely four-lobed; ovary of the staminate flower subconical, minute and abortive; ovule 

 solitary, suspended, anatropous, raphe dorsal, micropyle superior. Fruit on stout pedicels from 

 3 to 10 millimetres long, drupaceous, globose, crowned by the remnants of the enlarged pale 

 stigma, brownish purple, lustrous, from 4 to 5 millimetres in diameter ; sarcocarp thin ; nutlets 

 four, irregularly three-seeded, obtusely angled, dark-brown, from 3 to 5 millimetres long and

In Florida, a tree, sometimes from 10 to 12 metres high, with a tall often crooked trunk occa- 

 sionally 10 centimetres in diameter and covered with thin, smooth, nearly white bark, becoming on 

 old individuals darker-colored and broken into narrow scales, and small ascending branches green 

 when they first appear, becoming light gray and finally nearly white, and marked by numerous 

 round elliptic lenticels ; or often a shrub.

2 Carl Wilhelm Leopold Krug (1833-98) was born in Berlin, and in 1857 engaged in business in Porto Rico, where later he 

 became German and British Vice Consul. In Porto Rico he made large collections of plants, and bore the expenses of other 

 collectors- After his return to Berlin in 1876 Krug became during the remainder of his life the associate of Urban in the study 

 of the West Indian flora (see Urban, Ber. Deutsch. Bot. Gesell. xvi. Gen.-Versamml. 23 ; Symb. Fl. Ind. Occ. i. 90 ; iii. 69. — Schu-
