Tricoryne simplex

Tricoryne simplex

It is somehow heartening to know that it is always spring or summer somewhere in the world. Another thank you to David M. aka petrichor@Flickr of Sydney, Australia for sharing one of his photographs (original via BPotD Flickr Group Pool). Here's another plug for David's weblog as well, Kipili.com, with near-daily photographs of Australian plants.

The genus Tricoryne contains seven species, six of which are endemic to Australia (and one that is also found in New Guinea). Tricoryne simplex is one of the Australian endemics, native mainly to coastal New South Wales. Herbarium records seem to indicate one disjunct population in Queensland near Brisbane and a second disjunct population in the interior of NSW near Cobar, but these seem to be so far from the main distribution range that I wonder if the information has been verified. To see the herbarium records map, visit the New South Wales Flora Online record for Tricoryne simplex, then click on the “AVH map” button to view records from the Australian Virtual Herbarium. It's quite possible that these disjunct populations exist (or existed at one time), but it is also possible that there is some error in the location data, that an error occurred while keying in the location data or that a misidentification occurred.

It seems that it has a not-so-commonly-used common name: yellow rush-lily. This moniker makes more sense if you view photographs of the entire plant: Tricoryne simplex via the Tricoryne simplex via Plants of Sydney.

Lastly, I should note that Tricoryne is typically associated with the Anthericaceae, a plant family that has now been lumped into the Agavaceae (but see comments below – it looks like Tricoryne has been moved into the Hemerocallidaceae.

What's with the twisty buds? Characteristic of the (former) family or genus?

The New South Wales Flora online says "Tepals free, spirally twisted after flowering, later falling,.." so those apparently are not buds, and this was given as a characteristic of the genus.

fine camera work
if this is an herb how so

do you ever plant by the moon up there
my grandfather did in long ago days

we have cooled off in my part of florida
but the drought is still with us

Currently (APG) in Hemerocallidaceae (or Johnsoniaceae)

Thanks, David - duly noted (I'd incorrectly assumed that this genus would have moved with its typically associated family into the Agavaceae, and tagged it with the family).
