MR. J. MIERS ON THE HIPPOCRATEACEJE OF SOUTH AMERICA. 377 
gitudine, apice truncato, centro cavo; stigmate in cavitate punctiformi ; ovarii loculis 
4-ovulatis : fructu maximo, pyriformi-ovato, supra basin subito angustato ; seminibus 
magnis, angulato-oblongis, circa 6. In Brasilia, prov. Rio de Janeiro: v. v. in flore, 
monte Corcovado; v. fruct. sicc. in hb. Mus. Brit., Itagoahy (Bowie and Cun- 
ningham). 
The specimen which I collected in flower agrees with the fructiferous drawing of 
Velloz's Clercia passiflora; and as Cunningham's fruit accords with that in the same 
drawing, there is no doubt of their specifie identity. The flowering branches are straight, 
somewhat slender, with axils ¿-12 in. apart ; the leaves are 43-54 in. long, 21-25 in. broad, 
on a petiole 53-6 lines long; the panicle is 12-21 in. long, the peduncle 9 lines; the three 
first branches (each bare at its base for the length of 5 or 6 lines) are 13 in. long, and 
furnished at short intervals with alternate branchlets, which are again subdivided, thus 
forming an intricated corymb of very numerous terminal flowers, which expanded are 
each 3 lines in diameter; the white petals become yellow in drying; the disk, ovary, and 
style are pale green. The fruit is 53 in. long, with a diameter of 33 in. ; the pericarp is 
rather smooth, yellowish, becoming blackish and hard when dry, 6 lines in thick- 
ness, the dissepiments being evanescent ; it contains six seeds, oblong and subangular by 
compression, each 2 lines long, 1} in. in diameter, and partly covered by a whitish papy- 
raceous brittle eoating, mostly fallen away, consisting of cellular tissue analogous to the 
white arilloid covering which I observed in the living seeds of the following species; 
beneath this arilline we find the testa of a lightish-brown colour, somewhat brittle, coria- 
ceous, marked near the angle at one extremity with a round hilar cicatrix, from which 
rises a narrowish ribbon-shaped imbedded raphe, which soon becomes subdivided into 
innumerable ramifications, spreading over the entire surface, and lost in a network of 
fine spiral threads; the inner membranaceous integument adherent to it encloses the 
embryo, consisting of two large fleshy cotyledons, without albumen, united at a point 
near the hilum by a small radicle, imbedded between them.
