Title: Not Olsynium junceum (1577)
Post by: arisaema on July 15, 2024, 10:54:43 AM: I'm not sure what the seeds will grow into, but it looks like it might be a Sisyrinchium? If you donated or received these seeds please make a note of it not being Olsynium junceum, compare with the Holubec collection of the same species:

I have not seen Olsynium juncium seedlings recently enough to remember what they looked like. I do know that the adult foliage is quite coarse. It is possible [even likely] that juvenile foliage exhibits considerable variation

Post by: arisaema on August 26, 2024, 01:31:59 PM: The mystery not Olsynium junceum is flowering - and I'm lost as to what it might be... Any clues? I'll cross-post in plant identification.

Both 1577 and 1578 appear to be this misidentified species, both were listed under Olsynium, and both seem lovely, just not that.

Arisaema,

This is Olsaynium Junceum:

No, that one is (possibly) the same misidentified plant. This is Olsynium junceum, notice the "Juncus-like" foliage:

Your picture is of Olsynium Juncium ssp juncium.

Olsynium Juncium exhibits considerable variability especially outside the ssp juncium.

Not this much, and if you're ignoring the foliage (you really shouldn't) there's still the issue of the missing style... This is not Olsynium junceum, and I'm not even sure it's an Olsynium/Sisyrinchium.

Post by: Tomte on August 26, 2024, 07:25:54 PM: Looks a bit like hesperantha to me, but I‘m no expert on south African bulbs, most of which are not sufficiently hardy for my climate. I recall also having some similar seedlings in a batch of Olsynium from the SeedEx once (junceum or douglasii), but they did not survive for long, possibly for that very reason.

Post by: Tomte on August 26, 2024, 08:03:05 PM: I may add that hesperantha coccinea is a widely grown plant that comes in various shades including light salmon, so a possible candidate imposter..
