244 PARASITISM OF CUSCUTA AND OROBANCHE 
ceo.* Squame tubo basi et semet adnatz, apicibus incurvis, 
integris, fimbriatis.+ 
tylus unicus brevis, longitudine stigmata 2, linguiformia 
subulata, purpureo-sanguinea eequans. Ovarium basi solidum 
et viride, evasculum, cæterum cellulosum, albuminosum, bilo- 
culare, ovulis cujusque loculi 2, erectis, foraminis situs hilum 
prope, tegumento 0 discreto. 
ZEstivatio leviter imbricata, apicibus leviter inflexis. 
This species is just coming into flower, it is conspicuous 
from its size and its colour. 
— The specific characters can only be drawn from the inflo- 
rescence and envelopes of the sexual organs, no peculiarity 
appearing capable of detection in the axis and its appendages. 
The stigmata in this species have precisely the same structure 
asin the last, and present no furrow down their inner face, or 
any symptom of deficiency of stigmatic tissue on the outer, 
both curious anomalies. 
This species although very generally found. on a species 
of Salix, up which it climbs to a considerable height, also oc- 
curs on Populus, and in one instance on Eleagnus Sinjit. 
On the poplar its effects were evidently deleterious, althoug 
the tree from its greater size might be supposed better able 
to withstand its effects than the Salix. The effects on the 
only branch of the Sinjit to which it had become attached, 
were also injurious. The parasite not being limited to one 
species, is a proof that it eliminates its own food, that is, 
it alters the juice of the stock. The presence of Strychnine 
in its Viscum is no proof to the contrary. The Strychnine 
may be the only material in the Viscum that exists, corres- 
pondingly in the stock. 
rom the wounds of adhesion, the Sinjit exudes its fluids, 
which subsequently assume the form of a laminated transpa- 
rent gum, not unfrequently assuming the form of a fungoid 
excrescence. 
* Pollen nothing remarkable under 4 TA th. 
f Adhere to tube for a little divise above its base; and up to this also adhere 
together.
