It is a remarkable circumstance that eight attempts to 
impregnate A . corymbosa with pollen of A . fastigiata were 
made, and all failed. In one case the pollen was from the 
outer anthers, in the other cases from the inner. 
The hybridisation was accomplished in the end of May 
1887, and the seeds were sown soon after they matured. 
Germination of many of the seeds in heat took place in a 
week. The seedlings quickly formed bulbs, and the earliest 
ones flowered when they were twenty-one months old. 
Under a different method of culture they might have flow¬ 
ered sooner. 
As far as has been observed, no appreciable difference 
exists among them individually. The characters of the 
parents are very equally balanced in the offspring. The 
bulb at its present age —three years — (figs. 12, 13) 
shows many intermediate features. The tunics are more 
numerous than m A. corymbosa, and they are more swollen 
than in A. fastigiata. The leaves are well-defined, the 
parental features being singularly equally blended as to 
colour and texture. With regard to the histological ele¬ 
ments, the intermediate character is very evident in the 
marginal cells of the leaf. Taken from the same region in 
the three, they are very prominent in the one parent 
(A. fastigiata), not at all prominent in the other, and 
fairly prominent in the hybrid. In section the flower-stem 
is nearly circular. The flowers in size, colour, condition 
of the stamens, and other points, exhibit the same inter¬ 
mediate features. The relative power of flowering is also 
very noteworthy. On account of some peculiarity in its 
constitution A. fastigiata has not flowered for three years, 
while A corymbosa grown under the same conditions has 
flowered with great readiness every year. The hybrids
