Smooth Parrot-Pea (Dillwynia glaberrima)

This photo shows the front and back of the Smooth Parrot-pea flower, along with the leaves and a new bud.

Last week I posted a photograph of an unidentified pea flower, which was subsequently identified by John as a Smooth Parrot-pea (Dillwynia glaberrima).

As John mentioned in his comment, Dillwynia species of plants have a few distinguishing characteristics, and once I was alerted to these, I couldn’t resist looking up the Smooth Parrot-pea in Enid Mayfield’s field guide ‘Flora of the Otway Plains and Ranges 2‘ which includes very detailed illustrations of a number of pea flowers.  Happily, the Smooth Parrot-pea is one of them.

Armed with all of this information (thank you John and Enid) I will attempt to explain the distinguishing features as simply as I can.

According to Enid Mayfield, Dillwynia species have almost cylindrical leaves with a groove along the leaf on the upper surface. The leaf of the Smooth Parrot-pea is long, thin, hairless, and has a ‘recurved’ tip, meaning the tip of the leaf curves back. The stem is also hairless.  In fact, the name attributed to the plant,  ‘glaberrima’ stems from the word ‘glabrous’ a term used by botanists to indicate that a section of a plant is hairless.

Smooth Parrot-pea flowers grow in small ‘pedunculate clusters’ which essentially means they grow in groups of 2 to 6 flowers  on a stem which forms off the main stem.

Pea flowers have five petals.  The large upright curved petal at the back, called the ‘standard’; two small side petals (often not noticed) called ‘wings’; and the two petals which stick out to the front in a wedge shape, called the ‘keel’.   In Parrot-pea (Dillwynia) species, the standard petal is always wider than it is high.  This is such a useful piece of information to have as I can immediately see that some of my unidentified photographs from last year are Dillwynia.  So there is a chance I may yet identify them if I keep learning.

Thanks to John who identified this flower as the Smooth Parrot Pea (Dillwynia glaberrima)

    1. Thank you – I was extremely grateful to John who initially identified it. However, I have been reading up in field guides and am trying to get my head around the distinctions. I have a few more that I can see are different, and am just trying to work out what they all are. Thank goodness for the Macro lens, I would have no hope without it! 🙂 Thanks for commenting. Lisa
