Mary Sue,
The technical details of style + filaments in Hessea and Strumaria can be
confusing, even with good technical jargon and illustrations. I have always
been bewildered that Snijman or someone else never merged these two, along
with Carpolyza, assuming they are a monophyletic lineage. It seems that the
justification used for expanding Drimia or merging Ornithogalum with Albuca
is comparable, especially when the character state of adnation of style and
filaments seems quite artificial.
None of which helps answer your question. Leaving floral details aside, I
have grown ssp. bulbifera for some years and it is very distinct
vegetatively since it offsets prolifically (every year each plant makes some
new offsets). These plants have linear, ascending, softly hairy leaves. In
contrast, the four different accessions (separate gatherings) of ssp.
discifera I grow  each has different leaf morphology/presentation, and at
least one has leaves similar to ssp. bulbifera as described above but the
plants are solitary. Offsetting in this genus in general is uncommon, and I
would describe all four of these ssp. discifera as solitary bulbs. All have
been under similar conditions for 5-10 years.
