SMALL: PLANT NOVELTIES FROM FLORIDA 389 
—— crowded on the short branches. Sepals mainly white, 
cent, the outer slightly so, the inner decidedly so, but not 
a Specialized wings, the outer appressed to and folded over the 
edges of the inner. Stam ens 8; filaments alternately narrow and 
(Generic name from the Latin referring to broader filaments 
which resemble horns with a lobe or tooth on either side at the 
base.) 
In a few places in the “scrub’’ of the southern lake region of 
Florida one may find a depressed shrub forming mats of dark 
green foliage on the almost snow-white sand of the ancient dunes. 
The prostrate branches are copiously branched into slender 
almost innumerable branchlets all of which bear numerous small 
narrow leaves. 
It is associated with a number of rare and local plants, such 
as species of Polygonella, Delopyrum, Chionanthus, Cyrilla, and 
Lechea mentioned on preceding pages. 
“ Dentoceras myriophylla Small. Shrub with prostrate radi- 
ating branches 2-20 dm. fone, copiously branched, often densely 
fastigiate; leaves very numerous, clavate, 3-I2 mm. long, often 
fascicled on the short branchlets; panicles usually dense, the 
racemes sr se emi outer sepals becoming ovate, boat-shaped, 
appressed; inner se epals much longer than the outer, oval or 
Se Pi ie often slightly obovoid, 2.5—3 mm. long; achene 
ovoid or ellipsoid-ovoid, about 2.5 mm. long.—Inland dunes, 
(“‘scrub’’), southern lake region, Florida. 
The plants are conspicuous on account of the green mats on 
the white sand in which the plant grows, the panicles of white 
flowers are small and the flowers themselves are intermediate 
between Polygonella and Delcpyrum. It differs from both those 
genera in the we be which closely invests the achene, and in the 
long styles. 
The type specimens were discovered by the writer on the 
inland dunes south of Frost Proof, Florida, April 18, 1920. 
“ DEERINGOTHAMNUS Small, gen. nov. A lowshrub with 
or cuneate type, somewhat coriaceous, oianabsly veined an 
finely reticulate. Flowers perfect or polygamous, axillary to 
leafy bracts, pedicelled, more or less nodding, solitary, or two 
or three together. Sepals 2—4, green, short, imbricate, appressed.
