elongated branchlet, on which the leaves are distributed in pairs, 
by distinct intervals, and towards the extremity become abor-

membranaceus, 10-nervis, fere ad medium 5-fidus, laciniis 
oblongis, acutis, 3-nervatis, apice callosis, zstivatione valvatis, 
demum reflexis, tubo intus piloso, persistens, immutatus et 
marcescens. Petala 5, erecta, lacinius equilonga et alterna, 
rotundato-oblonga, concava, subcucullata, unguiculata. Sta- 
mina 5, petalis inclusa et cum unguibus inserta; jilamenta

nacea et ciliata, apice repente inflexa; anthere parve, reni- 
formi-rotundatze, 2-lobe, lobis 2-valvatis, valvula antica breviore, 
et hine rima hippocrepica latissime hiantes. Discus fere ob- 
soletus, calyci adnatus, ovarium fulciens et ejus diametrum vix 
excedens, cum toro confusus. Ovarium superum, disco pau- 
lulo immersum, 8-loculare ; ovula erecta, in loculis solitaria. 
Stylus filiformis, longe exsertus, ultra medium patentim hir- 
sutissimus, superne glaber, profunde 3-sulcatus, Stigma bre- 
viter 3-lobum, lobis obtusis, adpressis, glutinosis. Fructus 
carcerularis, chartaceus, valde hirsutus, oblongus, calyce im- 
mutato inclusus, eo paulo longior, stylo persistente termi- 
natus, indehiscens, 3-locularis, seepius abortu 2- vel 1-locu- 
laris, loculis monospermis. Semen ovatum, lenticulari-com- 
pressum, structura omnino ejus Colletia. 
Arbuscule Chilenses valde ramose, ramulis confertis, tortuosis, 
decussatim divaricatis et oppositis, junioribus brevibus et spi- 
nosis ; folia integra, oblonga, in petiolum brevem cuneata, sub- 
5-nervia, nervis parallelis costata, supra glauca, infra albido- 
sericea, e tuberculo majusculo infra spinam egrediente cum flo- 
ribus glomeratim congesta ; flores fasciculati, albescentes.
