punte triangolari, equilatere, rappresentanti la metä dell’intiero petalo, ed ha il frutto 
con semi ad albume penetrato da pochissime lamelle, mentre nella L. minor, la parte 
valvata dei petali nel perianzio fruttifero & liguliforme e triangolare-allungata, e le in- 
trusioni del tegumento sono numerose sebbene poco profonde 
Nelle foglie non ancora espanse del germoglio centrale il picciolo ed il rachide 
sono coperti da una forma tutta speciale di tricorni, consistenti in ammassi di cellule 
addensate a pareti rigide che formano delle placche poliedriche dure, approssimate in 
uno strato continuo di apparenza grumoso-cristallina; le placche in parola con lo svilup- 
parsi delle foglie cadono; sembra che esse corrispondano allo strato cotonoso che tanto 
frequentemente riveste le parti giovani del grumolo centrale di moltissime palme.

C. Ledermannianus Becc. n. sp. — Scandens. Folia satis lata, pars 
inferior foliola gerens ca. 1 m longa vel longior, rhachis decidue-furfuracea, 
supra rotundato-angulosa, subtus apicem versus unguibus robustis armata. 
Foliola subaequidistantia, inter sese satis remota, lanceolata, in media parte 
latissima, superne inferne subaequaliter attenuata, apice breviter acuminata, 
subtus paulo pallidiora, ubique glabra atque inermia, nervis primariis 9 
tenuibus atque nonnullis secundariis minus conspicuis percursa, transversa- 
libus numerosissimis. Spadix © flagellis carens, foliis brevior, apice in 
appendicem excurrens, spathis primariis nonnullis tubularibus, laxe vagi- 
nantibus vel leviter inflatis, oblique truncatis; rami primarii adscendentes 
infra vaginam prope os inserti, rami floriferi approximati, divaricati, supra 
os spathae prope basin spathae sequentis orientes. Spathae secundariae 
breviter infundibuliformes, ore latae, truncatae. Involucrophorum extra 
spathulam affixum. Perianthium fructiferum brevissime pedicelliforme. 
Fructus pisiformis, abrupte rostratus, squamulis 48 — seriatis, concoloribus, 
flavidis loricatus. Semen globulosum asperum, albumine aequabili. 
: Scandent and apparently of moderate size. Leaves rather larger, no 
doubt cirriferous, but the cirrus is wanting in the specimen seen by me; 
the pinniferous part 4 m or perhaps more long; the rhachis fugaceously 
furfuraceous; with salient angle on the upper surface not very sharp and 
quite smooth, underneath it is unarmed in its lower part but furnished 
above with scattered or more or less confluent and robust claws. Leaflets 
aequidistant or rather considerably apart (6—8 cm) one from the other 0n 
each side of the rhachis, rather firmly papyraceous, lanceolate, largest at 
about their middle, almost equally narrowing towards both ends, the bar 
acute, the apex briefly acuminate; green on both surfaces, slightly paler 
underneath, with 5 slender costae and several rather distinct secondary 
nerves; transverse veinlets very numerous, approximate and rather sharp, 
all nerves and the margins quite smooth; the apex also without bristles 
or spinules; the largest leaflets (the lowest) 25 cm long & em broad, 
upper leaflets gradually smaller. Male spadix... Female spadix 
no flagelliform shorter than the leaves, terminating into a tail-like el
