punte triangolari, equilatere, rappresentanti la metà delP intiero pelalo, ed ha il frutto 
con semi ad albume penetrato da pochissime lamelle, montre nella L. minor la parte 
yalvata de. petal, nel perianzio fruttifero è liguliforme e triangolare-allungata, e 1c in- 
tiusiom del tegumento sono numerose sebbene poco profonde. 
Nelle foglie non ancora espanse del germoglio centrale il picciolo ed il rachidc 
sono coperti da una forma lutta spéciale di tricorni, consistenti in ammassi di cellule 
addensate a pareti rigide che formano delle placche poliedriche dure, approssimate in 
uno Strato continuo d, apparenza grumoso-cristallina; le placche in parola con lo svilun- 
pars, delle foghe cadono; sembra che esse corrispondano allo Strato cotonoso che tanto 
requentemente 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 
sulitus paulo pallidiora, ubique glabra atque inermia, nervis primariis 5 
tenuibus atque nonnullis secundariis minus conspicuis percursa, transversa- 
libus numerosissimis. Spadix g flagellis carens, foliis brevior, apice in 
appendicem excurrens, spathis primariis nonnullis tubularibus, laxe vam- 
nantibus vel leviter inflatis, oblique truncatis; rami primarii adscenden'es 
infra vag.nam prope os inserts, rami floriferi approximati, divaricati, supra 
os spathae prope basin spathae sequentis orientes. Spathae secundariae 
breviter mfundibuliformes, ore latae, truncatae. Involucrophorum extra 
spathulam aftixum. Perianthium fructiferum brevissime pedicelliforme. 
l'ructus pisiformis, abrupte rostratus, squamulis 18 — seriatis, concoloribus

Scandent and apparently of moderate size. Leaves rather larger no 
doubt cirriferous, but the cirrus is wanting in the specimen seen by me- 
tie pmmferous part 1m or perhaps more long; the rhachis fugaceouslv 
ur uraceous; 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 on 
each side of the rhachis, rather firmly papyraceous, lanceolate, largest at 
about their middle, almost equally narrowing towards both ends, the base 
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 
a nerves and the margins quite smooth; the apex also without bristles 
or spinules; the largest leaflets (the lowest) 25 cm long 4 cm broad 
upper leaflets gradually smaller. Male spadix . . . Female spadix 
no age i orm shorter than the leaves, terminating into a tail-like elongate
