(Gardn. 546). 
A very distinct species, having straight elongated branches, 
with axils 1^ inch apart ; leaves 1|-3| inches long, |-2 inches 
broad, on a rather stout petiole 2-3 lines long ; the terminal 
panicle is 6 inches long in flower, 8 inches long in fruit, with 
twenty to tvventy-four alternate patent branches 4-6 lines 
apart, 1-2 inches long, diminishing upwards, bare at base, the 
lower ones again branched, the upper ones simply spicate ; 
flowers 1 line apart ; sepals rather fleshy, very pilose on both 
sides, Ij line long ; tube of corolla fleshy, contracted in the 
middle, 1|- line long, its segments |-1 line long ; anthers 
cohering in the mouth by their scabrid summits ; ovary and 
style equal, glabrous ; stigma short, conical, pilose, sub- 
2-lobed.

COETESIA. 
This genus was established by Cavanilles, in 1797, upon a 
plant collected by Louis Nde in his overland jommey from 
Chile to Buenos Ayres. His account of this little-known 
plant is upon the whole correct ; but, as there are some points 
of structure unnoticed by him, I will here add the results of 
my own observations made from the living plant in 1825. I 
found two species — one in dry desert rtacts in the neighbour- 
hood of Mendoza, the other fifty miles to the eastward, in 
saline marshy ground, which is that described and figured by 
Cavanilles. This genus has been rightly placed in the Ehre- 
tiacece^ with which it accords in its tubular calyx, exserted 
stamens, bifid style, and baccate fruit : it approaches Tourne- 
fortia in its baccate 2-pyrenous fniit, each nut being 2-celled ; 
but it differs in its sohtary flowers, in the singular appendages 
found between the calyx and corolla, in the absence of a 
hypogynous disk, in its long bifid style, and in its persistent 
campanular calyx. The following is an amended character of 
the genus, from my own observations. 
Coetesia, Cav . — Calyx tubulosus, camosus, extus pilosus, 
intus densissime sericeo-villosus, ore dentibus 10-15 tereti- 
bus obtusulis subinaequalibus glabiis paulo divaricatis cum 
membranis brevibus inteijectis donatus, demum subcam- 
panulatim dilatatus et persistens. Appendices circa 5-10
