CONTRIBUTIONS TO BOTANY. 
culum in juniore setate filiformi-cylindraceum ; ovaria numero- 
sissima, illinc cum paleis totidem brevioribus interspersa, cre- 
briter circumposita, mox cohserent omnia in niassam solidam, 
centralia (aut superiora) libera et sterilia, ut in aliis speciebus. 
2. Acicarpa crassifolia, n. sp.; — glaberrima, caule subdecum- 
bente ; foliis inferioribus spathulato-lanceolatis in petiolum 
brevem latum cuneatis, superioribus subsessilibus, cuneato- 
ellipticis, subobtusis, carnosis, margine subrevoluto remote et 
obsolete sinuato-denticulatis, 3-uerviis, nervis subtus promi- 
nulis ; pedunculo solitario, terminali, monocephalo ; capitulo 
majusculo ; involucri foliolis 5-7, obovato-oblongis, acutis, 
mucronatis, membranaceis, margine crassiusculo, integro. — 
Maldonado, in dumetis areuosis, v. s. in herb. Hook. (Tweedie). 
Species prsecedenti valde analoga, sed folia viridiora, breviora 
et latiora, margine denticulata; planta 5-pollicaris ; folia alterna, 
1-2 poll, long., 6-8 lin. lat., petiolo lato, subamplexicauli, bre- 
vissimo ; pedunculus terminalis 1 poll, long., apice incrassatus ; 
capitulum fere 1 poll, diam., semiglobosum ; involucrum fere ad 
basin 5-7-partitum, laciniis patentibus; paleae setaceae vel spa- 
thulatae, ovaria concreta excedentes; corollae tubus gracilis, 
2^ lin. long.; limbus infundibuliformis, ultra medium 5-partitus, 
tubo fere aequilongus, segmenta oblonga, acuta*. 
3. Acicarpa bupleuroides,. Less. Linn. vi. 527 ; DC. loc. dt. 3 ; 
— erecta, glabra, dichotome ramosa; foliis oblongo-obovatis, 
basi in petiolum alatum subamplexicaulem angustatis, obtusis, 
integerrimis vel apice subdentatis, reticulato-venosis ; capitulis 
terminalibus ; involucro inaequaliter 5-foliolato, foliolis lineari- 
elongatis, calyce corollaque 4-lobis. — Brasilia meridionalis, in 
uliginosis (Sello). 
Species mihi invisa, ex desdriptione autem cl. Lessingii ab 
alteris manifeste distincta ; herba perennis, 1^-4 ped. alt., habitu 
Bupleuri rotundifolii ; capitulum parvum, eo Artemisia Absinthii 
vix majus; folia alterna, remota, 6 poll, long., 1^ poll. lat. 
4. Acicarpa procumbens, Less. Linn. vi. 527 ; DC. loc. cit. 3; — 
glaberrima, caulibus plurimis, procumbentibus, valde ramosis ; 
foliis lineari-spathulatis, in petiolum planum attenuatis, in- 
tegerrimis, mucronulatis, glaucis, membranaceis, 3-nerviis, 
nervis superne immersis, subtus prominulis ; pedunculis mo- 
nocephalis, primum terminalibus, demum lateralibus, folio 
brevioribus ; involucri segmentis 6, floribus brevioribus, in- 
tegerrimis, oblongo-ellipticis, patentibus, insequalibus. — Bra- 
silia meridionalis, v. s. in herb. Honk. (Sello). 
Planta habitu ad A. spathulatam accedens ; folia remo-
