266 ORCHIDEA. 
In Eulophia Pl. CCLXXXV. Fig. IIl., before the ap- 
plication of the pollen to the stigma, no tubes are to be 
found in the stigmatic canal, which is highly developed. The 
specimens examined were dried,: except the impregnated 
ovaria which remained nearly fresh. In this plant the ovula 
are situated on two distinct lines, but after impregnation they 
present a confluent mass. 
_ Neither in this, nor in the species represented Fig. Il. of 
the same Plate, have I seen the tubes attached to the ovules, 
but I am led to believe that this does not take place until 
a comparatively late period, the ovula not having reached a 
sufficient state of maturity. If thisis the case the maturity 
of. the ovula themselves is in some cases dependent on im- 
pregnation, on the farther investigation of this point we keep 
in mind those plants which have very young ovula at the 
time of flowering.

Do. pollinia reflected to shew the insertion of the

the clinandrium, or rather of its outer portion and the 
rostellum, which is as usual inflectile, and in this in- 
stance very broad.

In a case like this in which so intimate an union by 
contiguity takes place between the gland and the rustellum, 
ich is certainly stigmatic, impregnation must almost

theory.
