CONTRIBUTIONS TO BOTANY. 
I have united with this genus the Leucocera of Turczaninow, 
founded upon the Boopis leucanthema of Poppig, which agrees 
with Anomocarpus in all essential respects, except that the re- 
ceptacle is more convex, almost conical, and charged with per- 
sistent palese, after all the achsenia have fallen off, as in Boopis. 
These characters are hardly sufficient to claim a distinct generic 
rank for Leucocera — a name that would have been ill applied, as 
the spines of the achsenia are of a yellowish brown colour. The 
great difference in the form of the achfenia was scarcely recog- 
nized by Turczaninow — a feature better characterized by the 
name Anomocarpus, which I had long previously employed for 
the more legitimate species. 
Anomocarpus, nov. gen. — Involucrum gamophyllum, campanu- 
latum, plus minusve profunde partitum, membranaceum, 
plurinerve, nervis 15-21, parallelis, laciniis 5-7, triangulari- 
bus aut lineari-oblongis, acutis, erectis, interdum demum 
auctum et explanatum. Beceptaculum minimum, areolatum, 
nudum, rarius parce paleaceum. Flores ssepius pauci, inclusi, 
omnes foecundi. Calyx ovario adnatus, 5-angulatus, in flori- 
bus radii limbi lobis abortivis, in unico centralibus (ssepe unico) 
lobis 5, sequalibus, liberis, ovatis, acutis, denticulatis et mu- 
cronatis, erectis, demum patentibus et excrescentibus. Corolla 
omnes consimiles, tubo infundibuliformi imo coarctato, cum 
ovario articulato, limbo breviter campanulato 5-partito, lobis 
acutiusculis, crassiusculis. Stamina subexserta; filamenta 
imo in tubum brevissimum syngenesa, medio tubi corollse 
inserta, apice longiuscule libera, et conniventia ; antherce ob- 
longse imo in tubum accretse, in floribus radii ssepe polline 
destitutse. Ovarium oblongum, 5-angulatum, imo ad calycem 
adnatum, supra medium liberum, hinc conicum, 5-sulcatum, 
1-loculare, 1-ovulatum; ovulum funiculo brevi ex apice pen- 
dulum. Stylus filiformis, exsertus, apice paulo incrassatus. 
Stigma subglobosum, papillosum. Achcenia radii obovata, 
inermia, profunde 5-costata, costis transversim rugosis, apice 
nodis cupuliformibus stylum versus conniventibus (e lobis caly- 
cinis tabidis) munitis ; centralia iis radii conformia, sed supra 
medium lobis calycinis longissime excretis, acutissime mucro- 
natis, horizontaliter patentibus, profunde concavis, imo tubi- 
formibus, margineque tenui scai’ioso-denticulatis coronata. 
Semen ordinis. 
Herbse Chilenses, sapius pusillce et erectce, dichotome ramosa ; 
folia in dichotomiis solitaria, alterna, spathulato-lanceolata, 
longe petiolata', capitula parva, interdum demum aucta, in 
dichotomiis solitaria, breviter pedunculata.
