872 FLORA OF SOUTH AMERICA. 
before me closely resemble one I have received from Martius 
under the above name, but the leaves are more acute at the 
base, and the pedicels are shorter.—British Guiana, Schom- 
burgk, n. 627. 
766. E. citrifolium, St. Hil.—HMart. l. c. p. 114.—British 
Guiana, Schomburgk, n. 590. 
767. E. mucronatum (sp. n.), foliis coriaceis oblongis v. 
obovato-oblongis apice obtusis cum mucrone, basi anguste 
cuneatis, stipulis ramentisque petiolo longioribus, peduncu- 
lis nodoso-glomeratis vix petiolo longioribus, calycis laciniis 
acutissimis petalis oblongis subdimidio brevioribus.— Folia 
pleraque bipollicaria, apice subplicata, supra nitidula, subtus 
in sicco rufescentia v. subglauca, venulis parum prominen- 
tibus, petiolo 1-2 lin. longo.  Stipulee membranaceze, acutis- 
sime, bidentatz;. Ramenti floriferi secus ramos plurimi, non 
distichi, 2-8-flori. Pedunculi 3 lin. longi, Flores parvi, 
petalis oblongis. Drupa oblonga, 4 lin. longa.—Pirara, ' 
Schomburgk, n. 766. I cannot make this plant agree with 
any of Martius's descriptions, though it comes near both to 
E. nitida and E. campestris. 'The stipules are much longer 
than in either. 
. 468. E. rufum, Cav. Diss. 8, p. 404, t. 232 ? DC. Prodr.v. 1, 
p. 575.—Rio Quitaro, Schomburgk, n. 545. I have little 
doubt but that this is the plant described by De Candolle, 
and is probably Cavanille's species, and I presume it is the 
one referred by Martius to his E. nitidum, though the leaves 
are much broader and the peduncles longer than described by 
him in any of his varieties. 3

oblongo.elliptieis utrinque angustatis subcoriaceis subtus 
glauco-ferrugineis, stipulis ramentisque petiolo aquilongis v. 
parum longioribus, floribus dense glomeratis, pedicello flore 
breviore, stylis a basi liberis.—Pluribus notis cum E. mag- 
noliefolio convenit, sed folia apice minime rotundata et 
petioli stipulis sepissime breviores. — Ramuli cinerei, novelli 
leves, fusci, subcompressi. Folia 6-12 poll. longa, medio 
25-35 poll. lata. apice acuta v. acuminata, basi acuta v. leviter
