interval between the insertion of the corolla and that of the andro- 
ceum is generally pretty considerable. This singular form of the 
receptacle, causing the insertion of the stamens to be separated from 
that of the petals by a kind of internode with 
summit more or less dilated and often covered by a 
glandular dise, is particularly noticeable in Grewia 
(figs. 195, 196), and it is for this reason that this 
genus has been made the type of a series which it 
is impossible for us to preserve as distinct after 
what we have just seen in Corchorus. It is only 
artificially that we can make a subseries Grewiee. 
Grewia has a drupaceous indehiscent fruit, entire or 
more or less deeply lobed. In Desplatsia and 
Duboscia it is also indehiscent, but suberose- 
ligneous, ovoid, and with four or five cells in the 
former, almost globular, with prominent ribs, and 
more numerous cells (from eight to ten) in the 
latter. In Columbia the fruit is dry and provided 
with from three to five vertical wings. Sometimes 
it is completely indehiscent, its wings remaining 
intact ; sometimes, on the contrary, it is divided 
into two indehiscent shells, so that each of the 
Corchorus olitorius.
