D. spathulata

Im going to order some sundews and want to know if D. Spathulata has the dormancy requirment.
 
No, Drosera spatulata does not have any dormancy requirement as it is a tropical species.

And it is spelled "spatulata" not "spathulata".
 
Nope, no dormancy needed. It will produce alot of seed via self pollination. Most likely, you will get the 'Kansai' type.
 
Hmmmm, I think it more likely that you will get the "Kanto" type as it has the greater distribution. "Kansai" is found only in a small range in Tokyo.

:) It is the mark of a serious student of Drosera species to correctly spell "spatulata". If you get this one right, those that KNOW will say "Ah, a wise one!", and the gates of the kingdom will open! BTW, I mis-spelled this species for over 20 years, up to about 2 years ago!

Thanks again to our Editor/Moderator Pinguiculaman, for his efforts at keeping us looking good!
 
Really, "Kanto" is more common then "Kansai"? All people I know that grow one spatulata type is usually "Kansai".
 
D. spatulata "Kansai" is a naturally occuring hybrid between D. rotundifolia x D. spatulata and has been described as a new species, D. tokaiensis, by Nakamura and Ueda in 1991. It is of very limited occurrence in Shikoku and southern Honshu, Japan.
 
So is D. tokaiensis a 40 chromisome reproductive version of D. rotundifolia x D. spatulata like D. Anglica is a 40 chromisome reproductive version of D. rotundifolia x D. linearus(sp?)?
 
You are correct with D. anglica, which is 2N=40. As for the allopatric hybrid D. tokaiensis: D. rotundifolia (20 chromosomes) + D. spatulata (40 chromosomes)= D. tokaiensis (60 chromosomes).
 
What are all the other types of D. Spatulata that you guys are talking about like the Kanto, and the Kansai types. Are they hybrids?? thats what im guessing.

There are only two recognized forms of Drosera spatulata, respectively the "Kanto" form and the "Kansai" form.

The Kanto form has the most widespread distribution: from eastern Australia to central Japan. This form is quite variable across this range (you can see some photos of some forms that I cultivate at:
http://home.twcny.rr.com/tamlin/index.html ) This form is visually distinct by the fact that stalked glands occurr all along the lamina (leaf) almost to the plant's center as opposed to:

Drosera spatulata "Kansai" (please see the former post regarding the range of this species.) This is also known as D. tokaiensis, or D. x tokaiensis (depending on which expert is doing the talking). The lamina on these plants are longer and thinner, and the petioles are mainly glabarous.

Both forms are recognizable by the fruiting capsules: the sepals do not close over the buds, resulting in a starlike effect which is unique to spatulata.

These plants often are traded and sold as more exotic species (notably the Brasilian droserae) and have a reputation of disappointing growers, but they are all beautiful plants in their own rights, and gems in any collection. Their variability makes them fun to collect and compare.
