Leaves from 1 to 3 decimetres long ; leaflets twenty-one to forty-one, obtuse or occasionally 

 minutely mucronate at the apex, gradually narrowed below into short slender pubescent petio- 

 lules, slightly thickened and revolute on the margins, dark green on the upper surface, pale and 

 glaucous-pubescent on the lower surface, from 1 to 2 centimetres in length, and from 7 to 11 

 millimetres wide, with slender midribs and very obscure primary veins. Inflorescence from 8 to 

 12 centimetres long, the pistillate accrescent, becoming at maturity from 1 to 2 decimetres in 

 length. Flowers regular, minute, dioecious, on slender accrescent pubescent pedicels, from the 

 axils of minute ovate deciduous bracts, in many-flowered axillary or terminal hoary-tomentose 

 racemes; calyx campanulate, five-parted, the lobes ovate, acute, hoary-tomentose on the outer 

 surface, slightly imbricated in aestivation ; disk five-lobed. Staminate flowers appearing sessile 

 in the bud, their pedicels only slightly accrescent after anthesis; petals five, filiform, shorter 

 than the calyx-lobes ; stamens five ; filaments slender, elongated, slightly villous toward the base, 

 longer than the calyx-lobes, inserted between the lobes of the disk and alternate with the calyx- 

 lobes ; anthers introrse, two-celled, united except at the apex, opening longitudinally by marginal 

 slits; connective conspicuous, orbicular; pistillate flowers on short accrescent pedicels; petals 

 none, or very rarely present; stamens none; ovary compressed, unequally three-angled, villous, 

 hirsute on the margins, three-celled at least at the base, apparently two-celled above, two of 

 the cells small, compressed, and empty, the other larger, with two anatropous ovules; styles two, 

 subulate or recurved, sometimes of unequal length, stigmatic above the middle, persistent and 

 accrescent on the fruit. Fruit lanceolate, acuminate, narrowly two-winged, pubescent, ciliate on 

 the margins, with long spreading crowded hairs, slightly tinged with red, from 1 to 1.5 centi- 

 metres in length and about as long as the slender hairy pedicels ; seeds oval, acute at the ends, 

 pale yellow, 6 millimetres long. 



A shrub or slender tree, in Florida occasionally 10 metres high, with a trunk from 1.5 to 2.5 

 decimetres in diameter, and hoary-pubescent branchlets marked by the large obovate obcordate 

 leaf-scars of fallen leaves, rounded at the narrow base and showing the ends of three conspicu- 

 ous equidistant fibro-vascular bundles. 1 



Florida, Timb's Hummock, near Gossman Station, Dade County, J. A. Eaton, December 22, 

 1903 (Nos. 708 and 718) ; 2 Bahama Islands, near Nassau, John L. & Alice B. Northrop (No.

« The first description of Alvaradoa amorphoides is in Bentham's Planice Hartwegiance, published in 1859, where on page 12 

 it appears as " Mimosearum f gen. nov. ? — Habitus Amorphffi." 



2 Alvaradoa amorphoides is said to have been collected again in Dade County, Florida, and on Long Key in 1904 (see Bull 

 N. Y. Bot. Gard. iii. 424).
