202 MR. SPRUCE ON FIVE NEW PLANTS FROM EASTERN PERU. 
stamens combined at the base into a tube which lines the short | 
tubular base of the corolla, ——although it has the same character, 
of the outer tooth of the calyx of the axial flowers being pro- 
duced into a leafy lamina, which gives to Calycophyllum its 
name. 
There is some analogy to Bignoniace:e, in the campanulate sub- 
asymmetrical flowers with a short tubular base and an approach 
to a bilabiate limb. Indeed the flowers remind one much of those 
of Henriquezia, which on its side shows an approach to Rubiaces 
in the inferior ovary. The winged seeds of Capirona it has in 
common with the rest of the Cinchonez, and with all true Big- 
noniaceæ. 
Enkylista I have seen along the shores of the Amazon for full 
2000 miles. It perhaps extends downwards to the very mouth 
of the river, and it is said to be still abundant above the mouth 
of the Huallaga. On the latter river it is frequent; and I have 
traced it by the streams among the roots of the Andes up to a 
height of about 2000 feet. Capirona grows only on dry ground ; 
and I have not yet seen it at a greater elevation than Enkylista, 
nor anywhere far from the river Huallaga. 
The light tough wood of the Capirona renders it very suitable 
for the beams of houses; and the trees are mostly cut down when 
they have attained a suitable size; so that it is rare to find a 
well-grown or a flowering specimen. 
There is apparently a second species with subpilose leaves, 
attenuated at the base and apex, and with paler bark, in which a 
green tinge is always perceptible. It grows rather higher than 
C. decorticans, and is very abundant at Yurünaguas on the Hual- 
laga; but as I have never seen its flowers or fruit, and could 
therefore give only an incomplete character of it, I hesitate to 
signalize it by a distinct name.
