cens in the dull green leaf-blades, the short calyx-lobes, the smaller glabroua or nearly 

 glabrous corollas and the strigose capsules. 



In moist woods, Randolph County, Georgia. Summer. 



Page 903, in sixth line under Lysimachia Fraseri, read calyx-lobes for ' * pedicels. ' ' 



Page 909, before Sideroxylon, insert: 



la. SAPOTA Mill. 



Trees with spreading branches. Leaves alternate, often approximate near the 

 ends of the branchlets: blades thick-leathery, glabrous. Flowers clustered. Sepals 

 6, pubescent. Corolla-lobes 6, toothed. Staminodia nearly as long as the corolla- 

 lobes. Style elongated: stigma minute. Berry spheroidal, rough. — Differs from 

 Chrysophyllum in having staminodia and from Sideroxylon in its 10-12-celled ovary. 



1. Sapota Achras Mill. A tree with rusty-tomentose twigs. Leaf -blades 

 oblong to elliptic, varying to broadest above or below the middle, 5-12 cm. long: 

 pedicels rusty-tomentose, about as long as the peduncles: sepals 8-10 mm. long: 

 corolla 8-10 mm. long; lobes about § as long as the tube: berries 4-8 cm. in diameter. 



In hammoclis and waste places, southern peninsular Florida and the Keys. Naturalized 

 from the tropics. Summer. Sapodilla.

2a. LTJCUMA Juss. 

 Trees. Leaf-blades more or less elongated, usually broadened upward. Calyx- 

 lobes 5, in 1 or 2 series. Corolla white or pale : lobes 5, entire or nearly so. Anthers 

 blunt. Staminodia slender, shorter than the corolla-lobes. Ovary 5-eelled, or some- 

 times 4-6-celled: style columnar: stigma slightly dilated. Berry globular, or slightly 

 elongated, smooth. — Differs from Sideroxylon in the seeds which are without endo- 

 sperm. 



1. Lucuma nervosa A. DC. Leaf -blades oblong to elliptic, 10-20 cm. long, 

 acute or acutish: calyx-lobes 5, the inner ones rounded at the apex: corolla 7-9 mm. 

 long; lobes ovate: staminodia subulate: fruits globose-ovoid, 5-7 cm. long, smooth, 

 usually 2- or 3-seeded. 



In hammocks, Florida Keys. Native of northern South America. Summer. 



Page 918, after Fraxinus Pennsylvanica, insert: 



6a. Fraxinus Darlingtonii Britton. A tree resembling F. Pennsylvanica and 

 F. lanceolata in habit. Leaflets 5-7; blades thin, lanceolate to oblong-lanceolate or 

 ovate-oblong, 11 cm. long or less, usually acuminate, entire, bright green, often pubes- 

 cent beneath: samaras 5-7.5 cm. long, each with a narrowly elongate-linear wing 

 which is decurrent on the upper part of the slender fruit-body. — Differs from F. 

 Pennsylvanica and related species in the elongate-linear samara-wings. 



In woods, on stream-banks and hillsides, Massachusetts to North Carolina, Alabama 

 and Louisiana. 



6b. Fraxinus Michauxii Britton. A tree similar to F. Pennsylvanica in habit, 

 with velvety or glabrous twigs. Leaflets 5-7; blades thick, ovate, oval, ovate-lanceo- 

 late or oblong-lanceolate, 15 cm. long or less, usually acuminate, entire, deep green 

 above, paler and pubescent beneath: samaras 3.5-5 cm. long, each with a spatulate, 

 usually broadly spatulate wing which is decurrent on the stoutish fruit-body. — Differs 

 from F. Pennsylvanica in the thick leaflet-blades and the broad samara -wing. 



In wet grounds, New York to Illinois and North Carolina. 



6c. Fraxinus Smdlii Britton. A tree resembling F. Pennsylvanica in habit, 

 with glabrous twigs. Leaflets 5-7 ; blades thinnish, oblong-lanceolate, ovate-lanceo- 

 late, ovate or oblong-ovate, 15 cm. long or less, acuminate, entire or nearly so, bright 

 green above, pale and more or- less pubescent beneath, slender-petioled : samaras 3-5 

 cm. long, each with an oblong or linear-oblong, usually acute wing which is decurrent 

 on the upper half of the stout seed-body. — Differs from F. Pennsylvanica and the 

 related species in the stout fruit-body and the wing which tapers to both ends. 



On river banks, North Carolina to Florida and Louisiana.
