APPENDIX 1369 



irregularly toothed, closely hispidulous beneath, cordate at the base, deeurrent on the 

 petioles: staminate flowers with deltoid sepals, and a corolla 10-13 mm. wide: pistil- 

 late flowers with subulate or lanceolate-subulate sepals, and a somewhat smaller 

 corolla than in the staminate flowers: berries oblong or oval, 15-20 mm. long.

FAMILY 5. CALYCERACEAE Lindl. CALYCERA FAMILY. 



Herbs or partially woody plants. Leaves alternate : blades usually narrow, 

 entire, toothed or pinnatifid. Flowers small, in heads which are solitary at the 

 end of each peduncle, or sessile, the receptacle short or elongated. Involucres 

 of one or two series of distinct or united bracts. Calyx of 4r-6 more or less 

 accrescent sepals. Corolla elongated, the tube slender, the throat shorter than 

 the tube, the limb 4-6-lobed. Androecium of 46 stamens. Filaments adnate 

 up to the throat of the corolla. Anthers erect, adnate around the style. Gynoe- 

 cium of a single carpel. Ovary inferior. Style elongated. Stigma minute. 

 Fruit an achene, often crowned with the calyx. 



1. ACICARPHA Juss. 



Annual diffuse or procumbent herbs. Leaves various: blades of the basal ones 

 usually petioled, those of the cauline leaves sessile or clasping, all entire or toothed. 

 Heads sessile or short-peduncled, spiny at the base, the marginal flowers fruit-produc- 

 ing, the central flowers not fruit-producing. Eeceptacle elongated. Sepals erect, 

 persistent. Corolla colored, with a long tube and a short throat: lobes narrow. 

 Achenes more or less united to each other. 



1. Acicarpha tribuloides Juss. Plants mostly 1-4 dm. tall, glabrous: basal 

 leaves 3-11 cm. long; blades spatulate: blades of the cauline leaves oblong to lanceo- 

 late, clasping, all coarsely toothed: sepals about 1 mm. long, acuminate: corollas 

 about 3 mm. long; lobes lanceolate: achenes crowned with the accrescent subulate 

 sepals 4-5 mm. long. 



In fields and on roadsides, northern Florida. Naturalized from South America. 

 Spring to fall.

2a. Vemonia Harper! Gleason. Foliage more or less puberulent. Stems 1 m. 

 tall or more, divaricately branched above: leaves numerous; blades lanceolate, 1218 

 cm. long or smaller near the top of the stem, thin, acuminate, dentate-serrate, scabrous 

 above: corymbs 3 dm. wide or more, lax: involucres broadly campanulate, 7-9 mm. 

 high; bracts green, with ovate or triangular-ovate bases and erect elongated tips,

 Differs from V. Noveboracensis in the many-flowered (55 or more) heads and the 

 gradually narrowed bracts. 



In damp or wet woods, southern Georgia.
