378 MR. J. MIERS ON THE HIPPOCRATEACEA OF SOUTH AMERICA. 
' cayo et minute punctiformi; ovarii loculis 6-ovulatis: fructu majusculo, pyriformi- 
ovato, imo subito et breviter constricto, plurispermo, dissepimentis sspe imper- 
fectis, subtriloculari; seminibus 9-12, pressione subangulato-ovatis, tunica externa 
alba, carnosa, molli, arilliformi ; testa coriacca, vasibus spiralibus repleta: cet. ut in 
praeced. In Brasilia, prov. Rio de Janeiro: v. v. in flore et in fructu, Monte Corco- 
vado ; v. s. in herb. Hook., Corcovado (Gardner, 5388). 
This species is closely allied to the former, being distinguished from it by its lanceolate 
leaves, smaller fruit, and more numerous seeds. The younger floriferous branches are 
long and slender, with axils ¿ in. apart; but when they become fructiferous, they are 
greatly thickened, foliiferous, oppositely rectangular with the stem, and pendulous with 
the weight of the fruit. The leaves are 3-5 in long, 9-13 lines broad, on a petiole 3-44 
in. long; the axillary panicle is 13 in. long, its peduncle 5 lines, with alternate (that is 
to say, dichotomous) branchlets with a single bracteole, which are 4 lines long, gradually 
diminishing upwards till they are corymbously crowded, supporting very numerous 
flowers; these are 2-21 lines in diameter when expanded; the petals, of a whitish colour, 
become dark yellow in drying. The pyriform fruit, supported on a very stout peduncle 
4 lines long, is suddenly contracted at both extremities, where it is 27 lines thick; the 
pericarp is coriaceous, but hard and ligneous when dry, is 4 lines in thickness, its external 
surface being of the colour of an apple, freckled with eoloured spots, and finely granulated ; 
it is imperfectly 3-locular; the dissepiments, being thin, are pushed out of their normal 
position by the unequal growth of the seeds, and sometimes consequently become torn or 
fenestrated ; the seeds, attached to the central axis, assume various directions, but always 
placed so that the hilum and radicle are directed towards the centre; they are 15 lines 
long, 9 lines broad, oblong, somewhat angular on the sides by pressure, and flatter 
upon the hilar extremity; the external coating, which I have formerly called an «arilline, 
is quite entire, white, fleshy, 1 line in thickness, smooth, and polished, becomes finally 
soft and somewhat pulpy, composed of cellular tissue, mixed with glandular cells, in 
which 1 did not observe any spiral vessels ; beneath this are the two proper integuments, 
agglutinated together, in the form of a thin coriaceous shell, internally filled with the 
network of spiral threads of the raphe, and closely investing the exalbuminous embryo, 
formed of two fleshy cotyledons, united at one extremity by a small semiorbicular radicle 
imbedded in corresponding recesses of the cotyledons.

From the close resemblance of the fruit and seeds to those of the two preceding 
species, and from the general habit of the plant, there can be no doubt that it is con-
