166 REPORT ON BRAZILIAN PLANTS. 
pistil, although without visible ovules, and a flower I possess of the 
same species is also hermaphrodite, whilst those of Mr. Spruce’s 
specimens of À. bicolor are male, without any vestige of ovary; and 
we know how very different the stamens often are in the male and in 
the hermaphrodite flowers of the same species of Clusia. Our plant is 
specifically well distinguished from St. Hilaire’s, by the foliage and 
petals. A third species from Surinam, 4. purpurea, Splitg., is unknown 
to me: it is described as 5-petalous, like ours, but with purple flowers, 
and only nine sepals. 
Arrudea ? bicolor, sp. n. ; foliis petiolatis obovali-cuneatis margine recur- 
vis, venis vix conspicuis, corymbis (masculis) terminalibus paucifloris, 
sepalis ultra 20, petalis 5.—Frutex in arbores parasiticus, undique 
glaberrimus, ramis teretibus. Folia 3-5 poll. longa, supra medium 
13-21 poll. lata, apice rotundata, basi in petiolum semipollicarem 
longe angustata, costa media subtus prominente, venis lateralibus 
parallelis tenuibus v. sæpius omnino évanidis. Flores ad ‘apices 
ramulorum 3-9, dispositi in cymas breves trichotomas breviter pedun- 
culatas, multo minores quam in <. clusioide, vix enim 14 poll. dia- 
metro; in speciminibus suppetentibus omnes masculi. Sepala 
(v. bracteæ) cirea 22, concava, coriacea, arcte appressa, exteriore 
brevissima et late orbieulata immarginata, interiora gradatim majora, 
intima late membranaceo-marginata et lacera. Petala 5, sepalis 
interioribus majora, alba, basi lutescentia, late obovali-orbiculata, 
apice emarginata, margine undulato-crispa, basi in unguem bre- 
vissimum latum angustata. Stamina in medio flore receptaculum 
totum obtegentia, numerosa (circa 80), arcte conferta, libera tamen : 
filamentis clavatis lineam longis ; antheræ in summo vertice sessiles, 
biloculares, loculis brevibus divergentibus longitudinaliter dehiscenti- 
bus. Ovarii vestigium nullum vidi. 
The two species of Vismia distributed— 7. dealbata, H. B. K., and 
V. Cayennensis, Pers.—are both well known, though not so common in 
collections as the V. Guianensis. The Malpighiacee are interesting, 
but require further study, and will be referred to in a future report.
