ID my favourite sundew

[piscesilim]

This is my favourite sundew.

Love it's shape and reddish colour.

It's flower can't fully open.

I wait from early morning until midnight. The flower never open.

I have more than hundred of this sundew. All seeds grown. All of them share this strange character.
However, they do produce a lots of seeds. What could it be?

One aerial view would help also. Can you take photo from top view?

 

[jimscott]

Beautiful plant. Is it D. ascendens?

 

[Not a Number]

I'd guess D. roraimae "Cerro Adaua" small rosetted form because it looks like mine. The flowers on mine always abort just before opening so I couldn't tell. If you get multiple scapes per plant that would lean me more towards that ID.

It could also D. capillaris, which is easy enough to ID by the seed.

 

[jimscott]

It does remind me of the "Long Arm'.

The flowers so far don't look like D. capillaris but there are D. capillaris going around labeled as D. roraimae.

Yeah, looks almost identical to my capillaris.
The only difference I see is shorter "arms," which could mean it's either just young or not the "long arm" type.

Nice plant.

Seeds look like this. Will take more photos tomorrow.

Looks like D. capillaris from the shape. Do they have little bumps running in parallel ridges length-wise (14-16 ridges) in pairs?

Here's my D. capillaris 'Long Arm', for comparison:

Here's my D. roraimae. The sepals (bristles) at the crown will help to identify the species also:

Looking at them side by side now I'm leaning towards D. capillaris

LOL! "roundandstickia"

Here's my capillaris 'Long Arm'

More photos.

Not sure whether the seeds have little bumps or not as the seeds too tiny.

I'd have to go with D. capillaris. It is likely the 'Long Arm' form, but it seems to be a more robust form, possibly one that has been crossed with the typical form?

There is a lot of variability between even the same species.
For example, the first and second pictures are of the same sundew at different stages:

Compare to this "typical" form that tends to stay close to the ground:

flower- what are your temperatures and humidity? There are evidently certain conditions that discourage certain Drosera flowers from opening.

I used to have a capillaris x rotundafolia that was exactly the same, right down to the aborting flowers. That's what I think it is.

 

[piscesilim]

Day temperature more than 40 °C. Night temperature 23-25 °C. Humidity 60-90%

I'm not sure about Rotundifolia x Capillaris because this is what mine looks like (leaves more circular):

Also, Lim has seeds from his plant, so I think it can't be a hybrid, as it would be infertile most of the time, and wouldn't produce viable seeds.

 

[amphirion]

has anyone considered drosera oblanceolata to be an option? why or why not? looks pretty similar to me.
