Quercus Rolfsii sp. nov. 
A rigid shrub, or a small tree becoming 7 m. tall, with ascending 
branches, the twigs light brown: leaf-blades cuneate in outline, 
leathery, 2.5-6 cm. long, mostly 3-lobed at the apex, or sometimes 
5-lobed, bright green, glabrous and finely reticulated above, pale 
and thinly stellate-pubescent beneath, the lobes mostly blunt and 
not bristle-tipped: acorns usually in pairs at the ends of short 
about a5 cm. broad, The scales appressed, eae whitish pubes- 
A very characteristic species, races on account of the deep 
and peculiarly shaped cup of the acorn. In the arrangement of the 
oaks adopted in my Flora of the Southeastern United States this 
plant would come next to Quercus undulata, from which it differs 
in the blunt lobes or teeth of the leaf-blades and the deep cup of 
the acorn. The type-specimens were collected in the pinelands 
near Ft, Lauderdale, Florida, by Prof. P. H. Rolfs, Mr. J. J. Car- 
ter and the writer in November, 1903 (no. 1044). 
aa succulenta sp. nov. 
A shrub, mostly about . tall, with soft spreading branches, 
the twigs gray-black: leaf- Pegs broadly linear to cuneate, fleshy- 
leathery, 2-4.5 cm. long, entire or with 3—5 slightly spinescent lobe- 
like teeth, smooth and glabrous above, tomentulose beneath: pistil- 
late flowers i in elongated peduncled spikes: acorns peduncled; cup 
saucer-shaped, 3-4 mm. high, 5-6 mm. broa upper scales 
obtuse; nut oblong-conic, 1-1.3 cm. long, only the very base in- 
cluded in the cup. 
As in the case of Quercus Rolfsiz, this plant is a live-oak. It 
is remarkable on account of its fleshy branches and leaves, and the 
very small, shallow and thin cup of the acorn. In these particulars 
it differs from all other members of the group to which it belongs. 
The type-specimens were collected near Ft. Lauderdale, Florida, by 
Mr. J. J. Carter and the writer, in November, 1903 (no. 1044). 
Phytolacca rigida sp. nov. 
erb 1-3 m. tall, or sometimes a tree becoming 6 or 7 m. tall, 
the a and branches mostly pena purple: leaf-blades lanceo- 
late or oblong-lanceolate, 7-34 cm. long, deep green, acuminate 
the apex, narrowed into petiole a bases: panicles SGemeaenly 
erect: pedicels 2-5 mm. long, stout and during anthesis slightly 
surpassing the subtending bracts, ae en than the diameter of
