Journ. Bot,, vol. iv. p. 100). The P. spectabilis, DC., has turned up 
again in sufficient quantity for general distribution. 
The following new Securidaca, from the banks of the Amazon, near 
Santarem, is remarkable from the fruit having a second wing, arising 
from the back, giving the whole samara a very peculiar form, though 
not easy to describe. i 
Securidaca dialata, sp. n.; scandens, foliis ovalibus obtusis retusisve 
basi subcordatis coriaceis subtus ramulisque puberulis, alis ovato- 
orbieularibus, carina latiuscula apice brevissime triloba plicato-cris- 
tata, petalis superioribus anguste oblongis, alis fructus geminis fructu 
subbrevioribus, postica angusta antica latissima cristeeformi.— Frutex 
super arbores alte scandens. Folia breviter petiolata, 2-3 poll. 
longa, 1-11 poll. lata. Racemi breves, multiflori. Bracteas caducas 
haud vidi. Flores majusculi. Calycis foliola 3, puberula, 13 lin. 
longa; ale vix unguiculatæ, 5 lin. longe, glabre nec ciliate. 
Carina unguiculata, supra unguem 4 lin. longa; petala superiora 
5 lin. longa, se invicem applicata, superne paulo latiora. Stamina 
8, usque ad 2 in tubum incurvum basi latiorem connata; filamentis 
superne libéris. Ovarium subsessile, obovoideum, compressum, apice 
oblique truncatum, intus 1-loculare, l-ovulatum. Stylus glaber, 
faleatus, a latere compressus, stamina æquans, apice oblique stigma- 
tosus. Fructus absque alis oblongus, 8-9 lin. longus, reticulato- 
rugosus; ala superior ex suturæ posticæ parte superiore orta, ob- 
longa, 5-6 lin. longa, 11—2 lin. lata, apice rotundata; ala major 
e tota fere sutura antica Lenis, in parte superiore 6—7 lin. longa, 
valde dilatata, plicato-rugosa, margine exteriore undulata v. sublobata. 
There are likewise two species of Catocoma: C. floribunda, a species 
widely diffused over tropical Brazil, found by Mr. Spruce at Santarem, 
growing to the tops of the loftiest trees and covering them with a 
crown of white and yellow flowers spotted with purple; and C. lucida, 
Benth., a Guiana species, now gathered on the Rio Trombétas, and its 
affluent the Rio Caipurá. Klotzsch (Linnæa, vol. xxii. p. 51) refers 
this genus to Bredemeyera of Willdenow, but without stating on what 
grounds. If the identity has been established by inspection of original 
specimens, Willdenow's character will require considerable modification, 
for the “drupa ovata nuce biloculari " is at total variance with the 
essential character of Catocoma.
