428 General Notes. | July, 
And Mr. M. W. Vansdenberg, of Fort Edward Academy, New York, an 
acute correspondent, has pointed out a marked exception in the case of 
Trillium erythrocarpum. This has the most slender filaments of all, and 
my correspondent calls attention to the fact that they are inserted on the — 
divisions of the perianth, well above their base, and the anthers are 
plainly extrorse. — Asa Gray | 
Spores OF BLODGETTIA CONFERVOIDES. — In Har'vey’s Nereis Am. 
Bor. there is a curious figure of a plant which he called Blodgettia con- 
Jervoides, which, if it correctly represents the fructification of the alga 
in question, is entirely unlike that of any other known alga. Bornet is 
of the opinion, from examining dried specimens, that the bodies figured 
as spores are parasites of some kind. Mr. F. W. Hooper, recently re- 
turned from Key West, gives the following as the result of his examina- 
tion of living specimens of Blodgettia :— 
“The figure of Harvey is curious indeed. To begin with the curious 
net-work of fibres bearing his so-called spores is, together with the spores 
entirely colorless. The anastomosing fibres are made up of short cells 
placed end to end. The cells are about three times as long as broad. 
The wall of the cell is distinct and the contentscolorless. It would seem, 
in many cases, that the so-called spores are only thin cellules swollen 
up, since they appear often in the middle of a filament. They are, more 
often borne on a side branch and are often irregularly placed, looking 
like a miniature bunch of grapes. This whole structure is not a part of 
the cell-wall, but ramifies between the layers of the cell-wall. As a 
proof of this we have this peculiar arrangement of fibres and spores (?) 
continuing right through from one cell of the Blodgettia to the next 
T am certain that the filaments and spores (?) have walls distinct from 
the layers of the cell-wall of the Blodgettia. A cross section shows 
distinctly. Generally two or three layers of the cell-wall of Blodgettia 
separate the parasite (?) from the cavity of the cell. I can see but little 
reason for calling it a unicellular alga. Morphologically it suggest 
those Callithamnia which have seirospores.” — W. G. FARLOW.

and Hepaticæ. P.J. Berckmans, in answer to a query by Dr. Thurber, 
states that Acanthospermum xanthoides and Clerodendron Siphonanthus 
were observed by him (in 1857 and 1873 respectively) in Georgia. 
Professor Tuckerman states that Willdenow’s description of Phaseolus 
multiflorus was founded upon Cornuti’s plant. :
