Tulipa ferganica

Biflores are a nightmare, I am glad I am not a taxonomist. Named as I got them.

Tulipa koktebelica from Crimea, flowers very early
Tulipa orthopoda from Kazakhstan, 2 forms which look very different? I have no idea.
Tulipa subbiflora from Tajikistan, a tiny plant which opens flowers within the leaf sheaths without showing buds

[Christian G.]

Tulipa polychroma from Iran
Tulipa biflora, a tall clone from Iran close to binutans
Tulipa binutans from Kyrgyztan, one of my favorites. Flowers for almost a month, curiously the flowers only open in the afternoon.

[Christian G.]

Tulipa buhseana from Kazakhstan
Looks very similar to binutans but flowers both earlier in season and daytime as well as for a shorter period. It comes from a steppe habitat while binutans is a mountain species.

[Christian G.]

Tulipa turkestanica 'Nuratau'
Tulipa turkestanica 'Zaamin'
Both from the Uzbekistan - Tajikistan border, I do not see much of a difference

[Christian G.]

Tulipa tarda 'Kashka Su' from Kyrgyzstan
Tulipa urumiensis, yellow form of tarda, allegedly from Iran, only known from cultivation

[Karaba]

Very nice series of pictures,Christian !

You have a great collection Christian, and I love how they grow so 'naturally' under good light conditions.
Yes section Biflores is rather confusing taxonomically but fortunately there's a very interesting article on the subject in the latest International Rock Gardener (vol. 148).

Thank you!

I am currently working on a thorough documentation of all of my 200+ tulip cultivars, from macro photos of flower parts, bulbs and bulb tunics to seedpods and seeds.

The key to biflores is highly appreciated, I'll go through it with my plants once I have good pictures of all parts. Still as ecologist I must say I am not overly fond of 'splitters' defining taxa by subtle morphological characteristics of a few plants, especially regarding vegetative parts. In many cases such classification cannot be upheld when looking at the full diversity within a tulip population. Infraspecific variation is ofter higher than between such 'species'. We would need to know more about pollinators and reproductive isolation as well as genetics to better define tulip species.

Anyway, let's continue with Saxatiles

Tulipa humilis, Dutch stock
Tulipa humilis violacea, Dutch stock
Tulipa kurdica from Iraq

[Christian G.]

Tulipa humilis alba caerulea oculata, Dutch stock
Tulipa rosea caerulea oculata, Dutch stock
This is the only humilis I have which produced flowers which droop when closed.

Totally agree and thank you for the reference, very interesting with lots of pictures
