106 MR. BENTHAM ON MALVACEJE 
bretonia, Schranck, with five broad bracts and indehiscent cocci 
(sometimes muricate almost as in Urena), and Lopimia, Nees and 
Mart., with numerous narrow bracts and the cocci enveloped in 
mucilage, have now been generally reunited with Pavonia, as being 
connected with other species by intermediate forms. An Austra- 
lian variety of P. hastata, Cav., has been established by F. Müller 
as a genus under the name of Greevesia, as having dimorphous 
flowers—perfect ones with the usual petals, together with abnormal 
pentandrous ones with small closed corollas. This is hitherto, as 
far as I am aware, the only instance observed in Malvacee, as the 
Stellarias of the group of Krascheninikowia are among Caryo- 
phyllee, but in neither case supplying a good generic character 
any more than in the numerous other orders where it is now 
known to occur. 
Asterochlena, Garcke, from the character given in the Bot. 
Zeit. 1850, p. 666, does not appear in any way to differ from other 
-Pavonias with more or less dehiscent cocci. 
Goethea, Nees et Mart., has also been united with Pavonia ; yet, 
in two species known to me, the habit and inflorescence, the large 
coloured calyx, short corolla, &c., seem to indicate differences more 
important than those which separate Urena. The GŒ. semper- 
florens, Mart., however, only known to me from Martius's figure, 
may possibly sufficiently connect Goethea with species of true 
Pavonia to justify the considering it as a section only. 
Malvaviscus, Dillen., with erect petals and a baccate fruit, seems 
at first sight very different from Pavonia; but the former charac- 
ter occurs in several true Pavonias, and the succulence of the fruit 
is variable in degree in different species of Malvaviscus. It is, 
however, known only in avery few, and whether it passes or not 
into the slightly mucilaginous outer coating of the carpels of 
Lopimia remains to be ascertained. Another character has been 
pointed out, which, if true, may be important,—that is, that the 
carpels are said to alternate with the petals in Malvaviscus, and to 
be opposite them in Pavonia. I have been unable to verify this 
character satisfactorily in our dried specimens. It is only in the 
fresh flower that it can be ascertained whether it may not be due 
to a greater or less degree of torsion, to which there is a tendency 
in many Malvacez. 
JULOSTYLES, Thw. 
This is a Ceylon tree, which, from some general resemblance in 
calyx and in habit to Aydia, had been published by Gardner as à 
second species of that genus. Thwaites very properly established
