Name the Bug # 49

You said we'd go far
in my white convertable car.
Reclining my seat;
leaning back in this heat.

Heat is the subject on everyone's mind in this part of the world, as Perth suffers through what is likely to be the longest extended period of temperatures above 30°C on record. So here's a bit of hot pink for today's ID challenge:

Attributions to follow.

Update: Identity available here. Photos from here and here.


  1. It looks to me like... oops, I need to sit out this round :)

  2. You can't get points for doing so, but you are allowed to comment if you want to raise the bar for other commenters ;-)

  3. This is probably too obvious, thus can't be right, but it looks like a Wisteria to me.

  4. Not a Wisteria because its a tree (Wisteria are vines) and the flowers don't seem to have the yellow spot at the center of the enlarged midline petal (is it called a banner?).
    Obviously a pea flower (Fabacea) of some sort. I'm going for the New Zealand endemic Weeping Broom (Chordospartium stevensonii) a rare and geographically restricted plant (from the Kaikoura Range) that is apparently making a great recovery from its porevious endangered status. Also starting to be used in gardens because of its obvious ornamental appearance.

  5. OOps, Thats what you get for skim reading and posting too quickly. The species is NOT doing well and is still restricted to a few hundred plants. The leafless branches seen in the lower picture are typical of the species so I'm fairly sure of my ID.

  6. Now that Adam has done the heavy lifting let's see if I can gank a point or two: Chordospartium was sunk into a more inclusive Carmichaelia by Heenan (1998).

    Thus this would now be Carmichaelia stevensonii. It also bears mentioning that a hybrid origin for C. stevensonii has been proposed by several workers, fingering a few different candidate parent species, once considered distinct genera but now absorbed into the expanded Carmichaelia. Not sure if there is much concrete evidence to back this scenario up, it is mentioned by Heenan who also documents several cases of both wild and garden hybrids in the genus, including some involving C. stevensonii.


    Heenan, P . B. 1998 : An emended circumscription of Carmichaelia (Fabaceae – Galegeae), with new combinations, a key, and notes on hybrids . New Zealand journal of botany 36: 53–63 .

  7. Adam loses points for getting the name wrong, so three points go to Neil. Adam gets two.

    Many of the New Zealand brooms are not surviving well. The centre of diversity for the group is the eastern South Island, which happens to also be the most generally altered part of the country.
