21. Exapurtum Hindsianum, sp. n., (Plate VIII.) ramis tortuosis, foliis simplicibus ovatis 
obtusis crenatis basi late subcordatis utrinque pubescentibus, pedunculis brevibus 1-2-carpiis.—Bay 
of Magdalena. 
Habitus, pubescentia et fructus HZ. rhoifolii, sed folia constanter simplicia. Petiolus fere pollicaris, lamina 
1-1}-pollicaris, inciso-crenata vel obscure lobata. Flores non vidi, sed sub fructu vestigia observavi staminum 
octo. 
Plate VIII. fig. 1, fruit cut across, with two perfect cells; fig. 2, the same, where one cell is 
abortive, both magnified.

22. Scuinus? discolor, sp. n., (Plate [X.) foliolis 1-7 parvis ovatis obtusissimis supra puberulis 
subtus incano-tomentosis, terminali inciso crenato subtrilobo, inferioribus multo minoribus integris 
crenatisve, paniculis abbreviatis, pedicellis fasciculatis.—Bay of Magdalena. 
Rami tortuosi, rigidi, cortice cinereo ; ramuli breves tomentoso-canescentes. Folia alterna vel in ramulis 
brevissimis fasciculata, vix cum petiolo sesquipollicaria. Foliolum terminale sepius semipollicare, lateralibus 
bijugis 5-4 lin. longis; nonnunquam preesertim in foliis superioribus terminale usque ad 8-10 lin. longum, 
lateralibus multo minoribus vel omnino nullis. Panicula terminalis foliata, ramulis axillaribus 6-12 lin. longis; 
fasciculi in quoque ramulo 2-4, sessiles, 8-15-flori. Pedicelli puberuli, 2 lin. longi. Sepala 5, puberula, colorata, 
siccitate rubra. Petala 5, calyce longiora (vix lineam excedentia) ovata, in alabastro carinato-concava, estiva- 
tione valde imbricata. Stamina 10, petalis breviora, in disco 10-crenato inserta. Ovarii rudimentum stylis 3 
brevibus terminatum. Flores hermaphroditos vel feemineos non vidi. 
Plate IX. fig 1, flower; fig. 2, the same, with the petals removed, both magnified. 
This plant has a very different aspect from most others of this genus; but 
in the male flowers, the only ones which I have seen, I can find no character to 
distinguish it.
