THE ORCHID REVIEW. 103 
light yellow flowers, with the disc of the sepals, petals, and lip ivory white, 
and a few purple spots near the base. It might, perhaps, be better 
described as having ivory white flowers, with all the segments broadly 
margined with yellow, and spotted as before, but without the purple 
suffusion seen in the original. The contrast of colour is very pretty. 
R. 
FERTILITY OF PAPHIOPEDILUM FAIRRIEANUM 
HYBRIDS. 
PossiBLy a record of failure may in some ways be as instructive as a 
record of success. It is for this reason that I do not hesitate to write out a 
complete list of my hybridising operations with respect to Paphiopedilum 
Fairrieanum hybrids for the years 1891 to 1898 inclusive. These attempts 
number seventy-two in all, and may be briefly summarized as follows :— 
On four occasions I have tried to fertilize a Fairrieanum hybrid with the 
pollen of another Fairrieanum hybrid, but in each case without success, no 
good seed pod having developed. 
I have used P. x vexillarium superbum as pollen parent twenty-six times 
on various species and hybrids, the result being that twenty of these attempts 
failed to produce good pods, and of the remaining six, when seed was sown, 
two only resulted satisfactorily, two seedlings being raised from one cross 
and four from the other. These hybrids have been named Paphiopedilum 
X Daedalus and x Zalmoxis, respectively. As a seed parent, P. X 
vexillarium superbum has been still less successful, no seedlings having 
resulted. My operations were seven in number, and from four of these no 
good pods resulted, while the seed sown on the other three occasions failed 
to germinate. 
Passing to P. x Arthurianum, I have been thrice successful, twice 
when using it as pollen parent in conjunction with Spicerianum 
as seed parent—when I was rewarded with two batches of P. x Minos 
seedlings—and once as seed parent, the pollen parent being X Pitcherianum 
magnificum. The failures number seventeen, though some, where seed has 
been sown so late as September and October, 1899, may yet have to be 
transferred to the list of successes. As pollen parent, there were seven 
attempts, and on two occasions only did a good pod fail to develop, though 
the five apparent good pods proved unproductive when the seed was sown. 
As seed parent, the failures to produce a good pod numbered only four, 
against six when the seed was deemed worthy of being sown, although as 
yet without result. 
With P. x Niobe I have been altogether unsuccessful.
