This species is obviously endemic and always grows together with Bromeliads.
Hitherto it has
been found in an area of only about 5 acres. The buds arise from a ring
of white wool in
which they are inserted and after the flowers have fallen a pit remains
as is typical of
Lepismium. This can be readily seen in, for instance, L.
megalanthum. The outside of the
outer perianth segments is brownish yellow with a darker midstripe. Sometimes
flowers are canary yellow.
Lepismium saxatile is a striking species of almost cereoid habit.
but with typical characters of
Lepismium, it seems to be related to L. epiphyllanthoides Backeberg which has larger (3cm
diam.) yellowish flowers and shorter limbed joints. This, too, is terrestrial,
growing in tuff
-holes in Southern Brazil, along with such striking plants as Pseudozygocactus
var. bradei Backeberg & Voll. with small. white, terminal,
rhipsaloid flowers and tiny
lingulate limbs. After many years I have been able to get for the first
time again living
material of this rare species through the kindness of Dr. Friedrich, Salto.
who also discovered
L. saxatile. I have also seen living material grown by a collector who
received a specimen
from Mr. G. Redecker of Tubingen and who gave the first description although
as cited above. For this reason I have described the new Lepismium with
Dr. Friedrich and
Mr Redecker as co-authors.
