same colour as that of the groundwork from which they happen to spring. The slight pubescence 
formed by these longer processes is visible to the naked eye in both species but is more distinct on 
the fall of I. palestina. On the other hand the filaments of the anthers of I. alaia bear numerous 
long, jointed processes, which are not present in /. palestina. 
As a garden plant, /. palestina is, if anything, more difficult to manage than /. alata. It has the 
same difficulty in ripening its growth, and its whole constitution seems to be less robust. Even in the 
wild state, the plants never grow so luxuriantly as do some specimens of I. alata. Imported bulbs, 
however, usually flower well in their first season at a slightly later period than I. alata. 
t /. T UBERGENIANA 
Foster in Gard. Chron. 1899, I. p. 225. 
Distribution. Turkestan, where it was discovered by Mr van Tubergen’s collector in the mountains near 
Tashkent. The exact locality has not been disclosed. 
Diagnosis. 
I. Tubergcniana J uno ; I. caucasicae valde similis sed folia glaucescentia, conspicue striata, segmenta 
exteriora barbata. 
Description. 
Rootstock, a rather slender bulb of the ordinary Juno type. 
Leaves, with distinctly horny ciliated margin, 6 in number, conspicuously striated, acuminate, of a 
light glaucous green. 
Stem , very short, 2 — 4 in., producing 1 — 3 sessile flowers. 
Spathes, acuminate, light green, with scarious tips, about 2 in. long. 
Pedicel, very short. 
Ovary, cylindrical. 
Tube, 1 — 2 in. long. 
Falls, 2 in. long, with lateral expansions or wings : of a bright and yet transparent yellow except 
on the blade, where the colour is opaque. There may be olive green markings along the centre of the 
haft and on the blade. The haft bears a yellow central ridge tipped with olive green, which as it 
emerges on to the blade breaks up into hair-like filaments. The tip is an undivided crest of yellow. 
Standards, very small, depressed, with a median tooth longer than the lateral tips. 
Styles, of the same transparent yellow colour. 
Crests, rather narrow, triangular. 
Stigma, conspicuous, oblong. 
Filaments, transparent, yellow. 
Anthers, yellow. 
Pollen, orange. 
Capsule, narrow, oblong, with thin membranous walls. 
Seeds, globular, resembling those of I. caucasica and /. IVillmot liana. 
Observations. 
I. Tubergcniana is obviously allied to I. caucasica, but the leaves are more glaucous and more 
distinctly striated. In colour it is very similar to /. orchioides , from which it is easily separated by 
the lateral expansions on the falls, and by the crest that splits up into hair-like threads. 
It is unfortunately not a robust species, and it seems to be dying out of cultivation.

[N.B. There does not seem to be any good reason for separating this from I. sindjarensis, of which it was 
probably only a colour variety. I. sindjarensis itself is variable in its growth. In some specimens 
the flowers and leaves are crowded together, in others the internodes are slightly longer and the 
inflorescence correspondingly less congested. The type of I. fumosa seems to have been a specimen 
of this kind with smoky, yellowish flowers.]

[N.B. This is apparently merely an albino form of I. sindjarensis I find among Foster’s MSS. a letter from 
Max Leichtlin to the effect that this Iris was brought from Mesopotamia by Bornmuller and that 
Leichtlin distributed it in 1895 as l • nusopotamica. The name assyriaca was subsequently given to 
the plant by Haussknecht]
