vegetation he considers to be his vegetatio terminalis, as exhi- 
bited in the ferns. They are not Monocotyledons. Independent 
of the circumstance, that no anastomosis of the vascular bundles 
takes place in the Monocotyledons, which is distinctly seen in 
the Rliizanthaceee, there is another fact which is opposed to 
this supposed mode of vegetation of the vascular bundles, and 
that is, that the curvature towards the outside is never per- 
ceived. Observations are then added respecting the anthers 
of parasites. The club-formed swellings of the columna geni- 
talis, in the Pilostyles, cover, at the lower side, from two to 
three rows of simple pressed tubes, flattened at the points. 
The anther, in Brugmansia, consists of four tubes ; in 
Rafflesia, an indefinite number of long drawn tubes are found, 
which all bend together upwards, and scatter their contents 
about through a single opening. The anthers in Hydnora 
consist of longitudinal tubes, which open themselves longitu- 
dinally ; an indefinite number of blunt conical tubes, entwined 
with each other and united into a little head, are seated on a 
thick foot-stalk in the SarcopJiyte sanguinea ; the upper free 
wall of these tubes bursts at the period of ripeness ; the burst- 
ing is efiected by the elasticity of striped vascular cells. The 
anther tubes in Hydnora have quite a similar structure. 
The author finally treats on the relationship of parasites 
with the fungi, with which they certainly correspond in many 
respects. The author’s statements are illustrated by seven 
tables, which are a valuable contribution to our knowledge of 
these plants. 
There is no doubt, that all parasitical plants belong to the 
Dicotyledons. The vascular bundles certainly do not often 
form a ring, but stand separated in one circle, which is also 
the case in many weed-like Dicotyledons; they are never, 
however, situated in several circles, as is the case in the 
Monocotyledons. I am not inclined to agree with the author, 
when he says, that the latter exhibit no anastomosis of the 
vascular bundles ; this is frequently the case with the nodes of 
the grasses ; the bending towards the outside is by no means 
a rule with the Monocotyledons. Many Rliizanthacece, ac- 
cording to the representation of the author, appear to have
