Prof, Michael Foster, F.R.S., to whom I am indebted 
for the following description and remarks, informs me that 
I. Bulefeldi is a shy flowerer, but that the foliage remains 
green all summer, not dying down in July and shooting 
again in August like the Oncocycli and many other Central 
Asian Irises. It dies down late in autumn, and does not 
shoot again till March or April. The colour of the flower 
is of extraordinary beauty and delicacy, very difficult to 
describe. As yet, Prof. Foster adds, I know no Iris like 
it, being unlike the Oncocycli, or any of our European 
dwarf species of the genus. It makes a distant approach 
to I. Blondowi, but without capsule and seeds its amount 
of affinity cannot be determined. Its distinctive features 
are its rhizome, foliage, spathe-valve, colour of flower, and 
especially the form of the narrow long cuneate segments 
of the perianth. Maximovicz makes it a variety of J. 
scariosa, Pallas (I. glaucescens, Bunge), but according to 
oct. Ist, 1886.
