supra glabris subtus pubescentibus trinervibus basi biglandulosis, spicis feemineis fasciculatis petiolo 
longioribus simplicibus ovarioque leviter pulveraceo-puberulis.—Tumaco, 
Rami fceminei adest frustulum ecrassum, lignosum, teres, cortice verrucoso. Folia 10 poll. longa, 7 poll. 
lata, supra nitidula, subtus ferruginea; costa media supra medium folii venas emittit primarias divergentes 
utrinsecus 3-4 ; cost laterales ad latus exterius tantum venis preeditw sunt 7-9; coste veneeque majores quee 
ad marginem attingunt ibidem seepius in denticulum glanduleformem excurrunt; omnes in pagina superiore 
folii depressee sunt, in inferiore valde elevate ; venze secundariee minus elevate, transversales et subparallele, 
rete venularum minorum minus conspicuum; glandule orbiculares, depresse, in pagina inferiore in axillis 
costarum. Petiolus 4 poll. longus. Spice interrupte, 5-6-pollicares, sepius geminew, basi squamis paucis 
Janceolatis setaceo-acuminatis stipate. Flores singuli ad axillam bractee parves squameeformis subsessiles, 
dissiti vel per 2-3 approximati. Calyx minutus, 4-fidus. Fructus nondum maturus jam magnitudine pisi, 
2-3-coccus, stylis 2-3, semipollicem longis, acutis, glabris, summo apice minute papillosis. 
789. Mapea Piriri, Aubl. Pl. Gui. 2. p. 867. t. 334. £. 1.— The leaves are very white under- 
neath, as described by Aublet, which is not the case with my specimens of Hostmann’s n. 1320, 
from Surinam, referred to this species by Steudel.—Isthmus of Darien. I have it also from 
Santa Martha. 
790. JarropHa nudicaulis, sp. n., glaberrima, foliis peltatis 5-lobis, lobis ovatis acutis eciliatis, 
stipulis glanduliformibus, panicula pedunculata corymbosa.—Monte Christi, in Columbia; in flower 
when everything else is burned up. 
Caulis crassus, mollis, rugosus, sexpedalis, apice tempore florescentiee foliis paucis parvis nascentibus 
coronatus; dum fructus maturescit folia evolvuntur 3 pollices lata, vix ad medium lobata, lobis apice 
rotundatis cum acumine abrupto brevi acuto; cilie glanduliferee omnino desunt. Stipule brevissime, 
irregulariter glandulzformes, pilis coronate longissimis tenuissimis implexis caducissimis. _ Inflorescentia et 
flores J. panduraformis et petala pariter coccinea videntur. Capsule glabra, glaucescentes, semipollicem 
diametro. 
791. Jarropwa, sp. n.?—Peduncle very long, and flowers smaller than in the preceding 
species ; leaves nearly the same, but as they are loose it is not certain that they belong to the same 
plant as the flowers.—Columbia. 
792. Curcas purgans, Medic.—Columbia. 
793. Cxrposconvs guinguelobus, Pohl, Pl. Bras. Ic. 1. p. 63.—Realejo; Gulf of Fonseca; Isle

794. Croton riparius, Humb. et Kunth, Nov. Gen. et Sp. 2. p. 90.—This should probably be 
referred to Klotzsch’s genus Astrea.—Columbia. 
795. Croton rivinefolia, Humb. et Kunth, Nov. Gen. et Sp. 2. p. 80. vel species ei valde 
affinis.—This is the same as Hartweg’s n. 695, but in both cases I have only seen male flowers, and 
therefore cannot satisfy myself as to its identity with the female plant described by Kunth, nor yet 
as to the genus to which it ought now to be referred. —Guayaquil.
