202 MR. SPRUCE ON FIYE IfEW PI>ANTS FROM EASTERN PERU. 



stamens combined at the base into a tube which lines the short 

 tubular hose 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 Bignoniacese, 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 Bubiaceae 

 in the inferior ovary. The winged seeds of Capirona it has in 

 common with the rest of the Cinchoneae, and with all true Big- 

 noniaceae. 



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 Capi/rona 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 Turiinaguas 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. 



V. Erythrina Amasisa, a new species with follicular pods. 



Erythrina Amasisa {Spruce). Arborea, foholis ovato-rhombeis 

 glabrescentibus, racemis terminalibus brevibus subpaniculatis, calyce 

 truncate, vexillo anguste ovato coraplicato carinara gamopetalara

Hab. Tarapoto, in sylvis montium inferiorum praecipue secus rivulos. 

 Amasisa* a Peruvianis designata est. 



Caudex 80-1 00-pedalis, basi subdilatatus, superne ramosus ; ramis baud

* Query — a corruption of " Ainor-sisa," i. e. "Love- flower" ?
