narrow thickly and evenly serrulate 1. and corymbose fl. orfr., 
from the other Mad. Epilobia. St. 6-18 in. high hard firm and 
slender, round below, angular but not always square upwards, 
quite straight and mostly entirely erect, but if accidentally from 
situation a little procumbent yet never rooting at the base. L. 
1-4 in. long 2-4 and 5 or even 8 lines wide with subparallel 
margins and so rather ligulate than lanceolate, the lower obtuse, 
the upper gradually more acute, the intermediate not wedge- 
shaped narrowed or entire at the base, but perfectly sessile with 
their leafy basal margins distinct full or plicate (not auriculate) 
and narrowly decurrent ; the upper 1. at the origin of a branch 
or fl. are often distinctly stalked like all the lower 1. In my 
Mad. ex. the 1. are quite smooth, but in some luxuriant Can. 
spec, from Palma they are minutely puberulous at their edges 
and on the midrib as sometimes in E. obscurum Schreb. Fl. 
much smaller than in E. parvifiorum, pale pink or rose. Stigmas 
cohering into an oblong club. Caps, very long and slender 2- 
2| in. long, 2 mill, broad, corymboselv crowded towards the top 
of the st. and all ripening nearly together ; their valves spread- 
ing but scarcely curled or rolled back. 
Although omitted by Webb and Berthelot, this is also a 
Canarian sp., found by myself in the great Caldera of Palma, 
and by Bourgeau in Gomera (Bourg. PI. Can. no. 747 in BH.).

(Bab., Grenier). 
4. E. obscurum Schreb. 
Smooth except st. upwards, buds, caps., edges and midrib of 
upper 1. which are finely adpressedly pubescent ; st. ascending 
procumbent and rooting at the base, much branched and angu- 
lar but not regularly square upwards, round below; 1. ratlier 
broadly subovato-lanceolate acuminate narrowing gradually 
from a rounded broadisli base, all quite sessile not decurrent but 
with two strong ribs running down the st. from their base, 
faintly and remotely denticulate and except the mostly very 
minutely puberulous edges and midrib smooth and shining; 
rac. erect leafy, fi. axillary scattered subremote, buds ovoid-ob- 
long, sep. lanceolate acute ; caps, short pubescent with strongly 
recurved valves, the lower ripening long before the upper ; seeds 
minutely granulate oblong-obovate pointed at the base. — Bab.
