polished ; all the leaflets are more or less acuminated at base, 
and often at their summit, are at least twice as long as broad, 
triplinerved, the lateral nervures springing at some distance 
from the petiole, are thicker in texture, opake and somewhat 
coriaceous, while the primary and secondary petioles are longer 
in proportion. On the other hand, in my plant the leaves are 
simply trifoliate or divided into only three leaflets, as in Boquila ; 
the leaflets are much larger in size, nearly as broad as long, 
conspicuously cordate and broadly truncated at base and obtuse 
at their summit, with a terminal mucro ; they are all equila- 
teral, quintuplinerved, the nervures originating at the base ; they 
are very reticulated, much thinner in texture, more transparent, 
and are deeply sinuated on the margin, the nervures in each 
salient angle (of which there are six or eight on each side) ter- 
minating in a long cuspidate excurrent point ; the lateral leaflets 
are both petiolulated ; the main petiole and three petiolets are 
comparatively shorter, and they, as well as the nerves and veins 
beneath, are all pubescent. In another specimen gathered at 
the same spot, and accompanying the fruit, the leaves are much 
smaller, also simply 3-foliate, the leaflets being more regularly 
obovate, slightly cordate, very opake, coriaceous, quite smooth, 
with thickened margins, which are almost entire or finely crenu- 
lated ; in other respects it corresponds with the above-mentioned 
specimen, and is evidently taken from the end of a branch, as 
its stem is thin and very twining. 
In L. biternata tbe stipulary leaves are large, orbicular, and 
sessile; in my plant only one remains, which is very small, 
linear, and attenuated at its base. The fruit is similar in size 
and shape to that of L. biternata, as figured in the Prodromus 
of the ‘ Flora Peruviana.^ The plant I have described is known 
at Concon as the Coguil, being the same name as that given in 
Concepcion and the southern provinces of Chile to the plant of 
Ruiz and Pavon. ‘Coguil’ is properly the name of its edible 
fruit, ‘ Coguil-boqui ’ that of the plant, the word ‘ boqui ’ being 
applied alike to all scandent shrubs ; the names attributed to it 
of ‘ Aguilboquil ’ and ‘ Guilboquil ’ by Dombey and La Perouse 
are certainly typical errors. In most botanical works, L. tri- 
temata is said to be a native of Peru, at Arauco ; but this is a 
mistake common to most of the specimens collected in Chile by 
Dombey. Arauco is a province bordering on that of Concepcion, 
and separated from it by the river Biobio.
