270 Plant. nov in Florida subtropica indigenae, John K. Small descriptae. 
Grove end Cutler (Small & Carter, no. 549). Bull Key, opposite Lemon 
City (Small & Carter, no. 642). Along Boca Ratone Lake (Small & 
Carter, no. 1242). 
15. Stillingia tenuis Small, |, c., p. 429. 
A shrub 3— 12 dm tall, with slender virgate stems or branches, the 
stem typically unbranched at the base, the bark ultimately with many 
transverse cracks: leaves early deciduous from the lower part of the 
stem and the branches, mostly approximate at the tips of the branches: 
blades linear or nearly so, commonly narrowly linear, 2—10,5 em long, 
finely, closely and shallowly toothed: staminate portion of the spike 
slender, 3—5 cm long, mainly red, the glands larger than the bracts: 
calyx about 1 mm long, shallowly lobed: gynophore about 6 mm wide: 
capsule depressed-globose, about 7 mm in diameter: seeds 4—4,5 mm 
long, shallowly rugose. 
A woody species related to Sfilingia aquatica Chapm., from which it 
differs in the more slender habit, narrowly linear leaf-blades, the slender 
red spikes with small bracts and large glands. 
Florida: The type-specimens were collected in the everglades between 
Homestead and Camp Jackson, in V, 1904 (Small & Wilson, no, 1580). 
Other specimens referable to this species are as follows: Between Cutler 
and Camp Longview (Small & Carter, nos. 1095, 1297 and 1440). 
16. Chamaesyce hyssopifolia (L.) Small, 1. c., p. 429. 
Euphorbia hyssopifolia L., Syst. Ed. 10. 1048. 1759. 
17. Chamaesyce pinetorum Small, l. c., p. 429. 
Perennial: plants pubescent with pale or white hairs: stem branched 
at the base, the branches ascending, spreading or prostrate, 8-—32 cm 
long, forked, more or less retrorse-hirsute: leaf-blades reniform to orbi- 
cular or ovate, 2—5 mm long, more or less revolute, paler and less 
pubescent beneath than above, entire, short-petioled: involucre broadly 
campanulate, about 1 mm high, copiously hirsute; glands relatively large, 
on broad stalks, elevated above the triangular ciliate involucral lobes, the 
appendages thick, very narrow or a mere border, pubescent without: 
capsules depressed, 2 mm wide, hirsute: seeds ovoid, 1 mm long, gray- 
papillose, triangled, obtuse, the faces scarcely wrinkled. 
A characteristic species, among North American forms, nearest to 
Chamaesyce deltoidea (Engelm.) Small, but of very different habit and 
aspect. The hirsute foliage, the ascending branch-ends and the pubescent 
involueres and capsules readily distinguish this species from C. deltoidea. 
Florida: The type-specimens were collected in the pinelands near 
the homestead trail between Cutler and Camp Longview in XI, 1903 
(Small & Carter, no. 836). Other specimens belong here as follows: 
Pinelands near Long Prairie (Britton, no. 192 and 193). Pinelands be- 
tween Homestead and Camp Jackson (Small & Wilson, no. 1665 and 
1891). Pinelands near Camp Longview (Small & Wilson, no. 1733). 
18. Gaura simulans Small, |. c., p. 432. 
Biennial, pubescent up to the flowers: stem erect, 1—2 dm tall, the
