Species unica P. LONGIFOLIA, Spruce, MS. (Plate XXXV.) 
Arbor fide Sprucei 20—30-pedalis, ramis adscendentibus, tota glabra exceptis inflorescentia ramulisque 
novellis tenuissime rufo-tomentellis. Folia (foliola solitaria?) oblongo-elliptica, breviter acuminata, 
basi obtusa, coriacea, nitidula ; maxima ultrapedalia, suprema multo minora ; petiolo (petiolulo ?) brevi 
crasso fulta. Racemi 1-3-pollicares, ad axillas solitarii v. subfasciculati, simplices v. ramosi. Pedi- 
celli solitarii v. subfasciculati, calyce subbreviores. Calyx 1} lin. longus. Petala ochroleuca, calyce 
vix duplo longiora. 
Hab. Tropical America. Caatingas near Panuré, on tlie Rio Uaupés, in North Brazil; gregarious, and 
often covering acres of ground among the scattered large forest-trees (R. Spruce, n. 2586). 
The inflorescence, the small flowers, and in a great measure the calyx, petals, and even 
the anthers, are very near those of Dalbergia ; but the stamens are entirely free, placing 
the genus amongst Sophoree, where I know of no one resembling it in other respects. I 
have not seen the pod: Mr. Spruce describes it as flat, rather broad, acuminate, and 2- 
valved, and he believes he had laid some in with the specimens ; but they appear to have 
been unfortunately lost before transmission to this country.

_ This genus stands alone in Leguminosæ, as combining the lofty climbing woody stem 
‚and habits of many Dalbergieæ with the digitately trifoliolate leaves of Podalyr ieæ and 
Genistee, whilst the flowers place it amongst Sophoree. Both the species known are 
amongst the handsomest of the Order, and the flowers of one are certainly the largest 
hitherto known. It has therefore been appropriately dedicated by Dr. ‘Welwsteck to the 
celebrated Portuguese poet Luis Camoes, author of the ‘Lusiade,’ in which - vri

as a soldier.
