reflexis et petalis angustioribus recedit. 
“ Planta alte scandens, ramulis cylindraceis, junioribus viridi-pilosis, adultis 
glabriusculis, suberoso-sulcatis.” Folia juniora late ovata, seniora plus 
minus alte triloLata vel interdum subquinquelobata, omnia breviter acu- 
minata, basi satis profunde emarginata, 4-8 poll. longa, 3-6 poll. lata, 
margine minute denticulata, supra breviter, subtus longe villosa ; petiolus 
teres, 1-8 poll. longus, longiuscule villosus, supra canaliculatus. Flores 
mascult apice pedunculi 6-16 poll. longi, longe villosi, globoso-capitati. 
Calycis tubus extra dense villosus, intus ellipsoideus, 2 lin. longus; lobi 
lineari-lanceolati, sub anthesi reflexi, circa 7 lin. longi, 1-1} lin. lati, extra 
dense villosi, intus sparsiuscule pubescentes. Petala erecta, obtuse 
lineari-subulata, 2 lin longa, $ lin. lata, breviter pubescentia, basi intus 
pilis longioribus moniliformibus munita. Axnthere suborbiculares, inferne 
replicate, connectivo lato mutico. Flores feminet et fructus ignoti—

The figure is from a specimen communicated in December 
last by Mr. Ed. André. As the plant has been referred to 
G. eriantha, it seems desirable to mention the chief differ- 
ences between the two species. The inflorescence of G. 
ertantha is spicate; that of G. malacophylla is capitate. 
The petals of G. eriantha are destitute of moniliform hairs, 
and are only slightly shorter than the suberect sepals ; 
whereas those of G. malacophylla have a tuft of moniliform 
hairs at the base, and are rather less than one-third as long 
as the reflexed sepals. : 
Most, if not all, of the species of Gurania are dicecious, 
and it is a curious fact that whereas the male plant is 
known in all the fifty-seven described species, the female 
plant is known in no more than nine, or less than one-sixth. 
It seems probable that the male plants are much more 
numerous than the female, though the relative incon- 
Spicuousness of the female flowers may, no doubt, often 
cause them to be overlooked. 
The genus Gurania has not hitherto been represented
