but the figures of ovary and fruit: 10, 11 and 12 are quite similar 
to the specimens in the Utrecht museum, as indeed all the other 
figures. Only the cilia at the top of the perianth leaves are figured 
somewhat shorter; this is, however, intelligible, as Beccarr had dried 
plants to work with and I had excellently preserved alcoholic material 
at my disposal. 
My conclusion is therefore that the plants found in Tjiomas belong 
to Sciaphila corniculata Byccart and that the distribution of this 
species is consequently not limited to New-Guinea, as Brccart had 
imagined. 
If we may now assume that the figures of S. nana given by BLUME 
are not very accurate — an assumption which does not seem to me 
to be very hazardous —, and if we further eliminate from BLUME’s 
deseription the unbranched shoot, which was probably due to an acci- 
dental property of the specimen described, then it seems to me, that 
we may well assume, that S. nana of Brumr and S. corniculata of 
Breccarr are names for one and the same species, especially as so 
far no other species of this genus have become known from Java 
except the so widely different S. tenella Br. 
There is however no complete certainty on this point, and as 
long as this is not the case, it will be best to affix the name of 
the accurately described Sciaphila corniculata Brccart to the specimen 
in question, and for the present to regard the name of Sciaphila nana Br. 
as not sufficiently well characterized. Possibly a future monographer, 
having many more data at his disposal, will be able to restore this 
name, but at present it is better to reject il.

Astronomy. — “Zhe Solar Vortices of Hare”. By Mr. A. Brestsr Jz. 
Communicated by Prof. W. H. Junius. 
On the more or less cyclonic configuration of the hydrogen flocculi 
around the spots on the spectroheliographs of the solar atmosphere 
and on the shifting and the becoming invisible of one of these 
flocculi at a short distance from a spot, Hare recently founded the 
hypothesis that the spots are vortices, which from the solar atmos- 
phere continually absorb the hydrogen, which there comes back 
every time as new protuberances or flocculi outside the spots. *)
