Plant. nov. in Florida subtropica indigenae, John K. Small descriptae. 269 
oblong, 2,5 mm long: seed about 2 mm long, hairy, the reflexed caruncle- 
lobe barely one half as long as the seed-body. 
A characteristic species related to Polygala Boykinii Nutt. but different 
in habit and typical condition with very numerous leaves. The flowers 
are commonly more numerous and smaller than in P. Boykinii, while the 
wings are obovate instead of ovate. The capsules are relatively longer 
and narrower than in P. Boykinii and smaller. 
Florida: The type-specimens were collected in the pinelands, along 
the homestead trail near Camp Longview, in XI, 1903 (Small & Carter, 
no. 1078). Other specimens belonging to this species are as follows: Black 
Point (Small & Carter, no. 829). Gossmans (Britton, no. 169). Long 
Key (mainland) (8mall & Wilson, no. 1806). 
13. Phyllanthus saxicola Small, l. c., p. 428. 
Annual, glabrous: stem 0,5—3,5 dm tall, simple or irregularly branched: 
leaves relatively numerous, erect or nearly so; blades leathery cuneate, 
5—9 mm long, obtuse, entire, bright green, short-petioled: flowers very 
short-pedicelled: calyx of the pistillate flowers less than 2 mm wide at 
maturity; lobes obovate: disk rather angular: capsule spheroidal, barely 
2mm wide: seeds less than 1 mm long, nearly as wide as long, papillose. 
A species related to Phyllanthus Carolinensis, but smaller throughout. 
It differs from P. Carolinensis in the small leathery approximate leaves, 
the smaller calyx with broader lobes, and the smaller seeds. 
Florida: The type-specimens were collected on projecting coral-sand 
rock in the everglades between Cocoanut Grove and Cutler, in XI, 1903 
(Small & Carter, no. 775). 
14. Croton arenicola Small, l. c., p. 428. 
Annual, sometimes partially woody at base: stem 1,5—4,5 dm tall, 
simple to the inflorescence or branched at the base, the branches like 
the stem stellate-glandular, forking above: leaf-blades thickish, ovate, 
varying to oblong-ovate, those of the upper leaves typically ovate, 1—3 cm 
long, coarsely crenate or sometimes crenate-dentate with few scattered 
stellate hairs at maturity: petioles '/4—'/s as long as the blades, pubescent 
like the branches: flowers monoecious: the staminate with lanceolate 
bracts 1—2 mm long, sepals oval to oblong, about 2 mm long: petals 
oblong to oblanceolate, white, somewhat larger than the sepals: stamens 
9—12, filaments pilose at the base: pistillate flowers solitary or clustered 
below the staminate: sepals spatulate, accrescent: petals mainly obsolete: 
capsules globose oval, 4,5—5 mm long: seeds 3-—3,5 mm long, punctate. 
Plants belonging to this species have heretofere been referred to 
Croton betulinus Vahl; the most closely related Croton occurring in North 
America is G. glandulosus septentrionalis, from which this species may be 
separated by the typically ovate and crenate blades of the upper leaves, 
Florida: The type-specimens were collected in pinelands between 
Cutler and Black Point, in XI, 1903 (Small & Carter, no. 822). Other 
specimens belonging to this are: Cape Florida (Henderson, early last 
century: Britton, no. 312). Miami (Curtiss, no. 5840). Between Cocoanut
