The Pogoniris Section 
N.B. The following are probably forms of 7 . variegata : — 
/. Uucographa, Kerner in OBZ. XIII. p. 313 (1863). This appears to be an albino form of 7 . variegata, in which 
the purple veining is replaced by white. It was only found once by Kerner at R 2 kos, near Buda Pest He 
searched again in the same spot, which he also showed to Dr A. v. Degen, but the plant has never been discovered 
again. The place, where it grew, has now been built over. 
I. lepida, Heuflel in Flora XXXVI. p. 621 (1853), collected in 1842 in the neighbourhood of Grebenac in 
Banat with inflated herbaceous spathes and white flowers with violet-veined falls is probably a form of 7 . variegata. 
It has, however, never been found again since its first discovery and it is impossible to identify it with any 
certainty. It is sometimes stated, though on what authority I do not know, that Reichenbach’s figure of 
/. lurida (Ic. IX. CCCXXXVII. fig. 764) was taken from a flower of Heuflel's plant but it does not tally with 
the description. It rather represents one of the smoky purple forms, which have been known under the names 
of I. sambucina and 7 . squalens and which are probably all hybrids of 7 . pallida and 7 . variegata. See also 
7 . atnocna (p. 169).

N.B. There is at Berlin a specimen from Meersburg collected by Busch in 1883 and, if this is the 
Meersburg on the opposite side of the Lake to Constance, we get a considerable westward extension of the 
habitat of this species. 
Diagnosis. 
I. variegata Pogoniris ; folia tenuia, conspicue striata ; caulis ramosus ; sfathae herbaceae, inflatae ; 
segmenta interiora lutea, exteriora purpureo venosa. 
Description. 
Rootstock , a compact rhizome. 
Leaves , deep green, distinctly ribbed ; those clothing the base of the stem are more or less falcate 
and not more than 8 in. long ; those of the non-flowering shoots are longer and more erect. 
Stem, 15 in. or less, bearing a terminal head of 3 flowers and 2 or 3 side branches, set in bracts 
and bearing each 2 flowers. In weak specimens the stem is sometimes unbranched and bears only two 
flowers in the single terminal head. 
Spathe valves, 1 — 1£ in. long, the inner valve being usually longer than the outer; light green, 
glossy, sometimes slightly flushed with purple and membranous only at the extreme edge, inflated. 
Pedicel, very short. 
Ovary , $ in. long, with six longitudinal grooves at equal intervals. 
Tube , | in. 
Falls. The obovate blade passes gradually without any constriction into the wedge-shaped haft. 
The yellow-white ground is veined with conspicuous purple or black-purple veins. In some specimens 
these run together on the outer part of the blade, of which the extreme edge is, however, often quite 
pale. The beard is of close set yellow or orange hairs, sometimes tipped with brown. 
Standards, rounded oblong with a short canaliculate haft, which together with the lower part of the 
blade is usually slightly veined with brown. The rest of the blade is bright yellow. 
Styles, narrow, yellow, keeled. 
Crests, long, narrow, pointed. 
Stigma, entire, rounded.
