gata, exteriora separata, interiora vero confluentia. Ovarium 
Ij lin. long., fructus non suppetunt.” 
Species mihi invisa, sed ex char, supra transcriptis manifeste 
videtur, ob habitudinem suam peculiarem, ad hoc genus perti- 
nere. Sic explicatur : — caule perbrevi, scapos plurimos brevissimos 
fere obsoletos monocephalos fulciente ; scapis exterioribus bberis, 
longioribus, e basi enatis ; foliis radicalibus lineari-spathulatis, 
integris, coriaceis.

28. p. 708 ; — “ csespitosus, caule brevi, crasso, scapis plurimis 
fastigiatis monocephalis munito ; scapis interioribus brevis- 
simis, et fere confluentibus ; foliis coriaceis, spathulatis, den- 
tatis, caulinis confertissimis ; involucri foliobs 5, ovato-tri- 
angularibus, acutis ; floribus viridibus, involucrum superan- 
tibus ; paleis subnullis.” — In Andibus ChUensibus, Prov. 
Maule, Depart. Linares. 
“ Caulis 4 poll, alt., 5 lin. crassus, radicem versus attenuatus ; 
folia 2^-3 poll, long., 8 lin. lat., grosse inciso-dentata ; capi- 
tulura circa 9 lin. diam. ; corolla lin. long., tubo filiformi, 
superne ampliore.”

9. Nastanthus Gayanus-, — Boopis Gayana, Philippi, Linn. 28. 
p. 709; — dense csespitosa, scapis subaphyllis, centralibus 
confluentibus ; foliis radicalibus, coriaceis, linearibus, pinna- 
tifidis, ultra medium nudis, laciuiis oblongis, obtusis ; invo- 
lucri foliolis imo connatis, lato-linearibus, obtusis; corolla 
brevi, subcylindrica, membrana exteriore tubi byalina et ab 
interiore viridi remota ; paleis setaceis. — In Andibus CbUen- 
sibus, Santa Barbara, Prov. Arauco (Gay). 
Folia radicaba 2^ poll, long., lamina 1 poll, long., cum lobis 
4^ bn. lat., lobis utrinque 4^5. Scapi exteriores liberi, 1 poll, 
long., 2^ bn. crassi, alii ssepe folio sub capitulum donati ; capi- 
tulum 9 bn. diam. ; involucri fobola brevissima, nonnulla lon- 
giora; corolla alba, vix 2 bn. long.; dentes calycini distinct!. 
2. Gamocarpha. 
The typical species was collected in Chile by Poppig, who de- 
scribed and figured it under the name of Boopis alpina. DeCan- 
dolle afterwards founded upon it his genus Gamocaipha, its 
name expressing the fact of the accretion of its palese, first indi- 
cated by Lessing, from whose imperfect account DeCandolle 
established his brief and defective generic character. Lessing’s
