identical, and the only apparent difference is that the leaves 
of P. Cotyledon are all, except the uppermost, peltate ; but 
this peltation varies in amount, and the allied Sprucean 
plant has both cordate and peltate leaves; I therefore 
quite expect that P. resedeflora and P. Cotyledon will, when 
more material is obtained, prove identical specifically. 
André describes his specimen as having uniformly (on 
upwards of one hundred flowers) obscurely umbilicate tri-. 
gonous apparently one-celled anthers, and remarks on the 
singularity of this structure, suggesting further, under 
great reserve, that if the character proves constant, P. 
resedeflora will constitute the type of a genus to be called 
Trigonanthera. Unfortunately the plate in the Flore des 
Serres gives no analyses; ours shows perfectly normal 
anthers. 
P. resedeflora is a native of the table-land of Bogota, 
where it grows on mossy trunks of oaks; it has long been 
cultivated at Kew, but by far the finest specimens I have 
seen are those figured, which were sent by Mr. Lynch from 
the Cambridge Botanical Gardens. 
Descr. Erect, quite glabrous, succulent. Stem cylindric, 
one to one and a half feet high, red, forked or subverti- 
cillately branched above. Leaves broadly orbicular-ovate, 
dark green, radical two to two and a half inches long, 
subacute, basal sinus very narrow and short; nerves seven 
to nine, radiating from the petiole, stout, reddish beneath ; 
petiole stout, two to three inches long, terete; cauline 
leaves opposite or whorled in threes, smaller shorter- 
petioled, very pale beneath. Peduncles one to three at the 
ends of the branches, two to three inches long, simple or 
with small opposite or solitary lateral branchlets, naked or 
with a few minute scattered imperfect amenta below the 
inflorescence. Amenta in short conical or long cylindric 
conical topped racemes, white, spreading, clavellate, obtuse, 
a quarter to a third of an inch long. Bracts orbicular, 
peltate, stipitate. Stamens several in each flower; fila- 
ments very short; anthers shortly oblong. Ovary pyriform 
or yo top rounded, with a very minute sessile stigma. 
Fig. (= Portion of amentum with flower; 2, bracts; 3, stamens; 4, ovary; 
5, vertical section of ditto — all greatly enlarged.
