PASSIFLOREJE OF ECUADOR AND NEW GRANADA. 27 
This is a very remarkable species, having orauge-coloured and 
yellow, tubular funnel-shaped flowers, the petals arising, not from 
the top of the flower-tube as usual, but from near the centre as in 
some species of Modecca or of Wormskioldia. 
The present plant does not appear to differ from that described 
and figured by Karsten, except in the much larger flowers. Until 
further researches prove whether or not there are more forms 
with the same peculiarity,it seems better to consider M. André's 
plant as a variety rather than as a separate species. 
Except in the peculiar origin of the petals, the plants do not 
differ in any way from Tacsonia; and hence it seems preferable 
for the present to keep Karsten's name as the indication of a 
section only and not as that of a separate genus. T. floribunda 
and its variety differ from the T. bracteosa, Planch. & Lind. J. c. 
p. 137, in the fact of the petals originating from the centre 
of the tube, not from the upper part. The last-named plant 
is made the type of a distinct section (§ Zacsoniopsis), and 
distinguished by the limb of the calyx (“ saltem quod sic perpe- 
ram dicitur ") being 5-fid, not 5-partite, and by the petals being 
exserted, ‘‘ bien au-dessus de la gorge du calyce, c'est-à-dire sur 
la portion dilatée du limbe, laquelle est simplement 5-fide, au lieu 
d'étre 5-partite." The “insertion,” or, more strictly speaking, 
the “ exsertion," of the petals in these plants, then, takes place (1) 
at the throat of the flower-tube, the most usual place ; (2) above it, 
as in T. bracteosa; (3) below it, as in T. floribunda. 
Owing to the scarcity or imperfect condition of the flowers of 
some species in herbaria, it is not possible to subject them to 
complete examination; but when better material becomes acces- 
sible, it is probable that other species will be found to possess 
the same peculiarity as T. floribunda. 
As M. André’s specimens of the last-named plant are excep- 
tionally good, I append a full description as follows :— 
Scandens, cirratus, glaber. Rami angulati. Folia 8-9 cm. long., 
10 em. lat. Petiolus 1-3 em., gracilis, glandulis 2-3 sessilibus 
onustus, Stipule lineari-lanceolate acuminate glanduloso-serrate. 
Laminz foliorum suborbiculares, basi rotundate, fere ad basin 3-5- 
secte, segmentis lanceolatis apiculatis serrulatis, medio paulo lon- 
giore et ad basinangustato; nervi subtus prominentes, nervi secun- 
darii remotiusculi. Peduneuli teretes, 1-flori, 8-10 cm. longi. 
Bractes 4 cm. long., 2 cm. lat., foliacez, oblongo-lanceolatz, serru- 
late, acute. Flores ad 12-13 cm. longi [basi aurantiaci, apice lutei,
