Author's notes

Hi Betty, Here's a poser for you, not that I expect an ID on it. I'll create Convolvulus sp and it can go in there in the short term, till I get a specimen sent off and pronounced on. The Convolvulus revision (Johnson, 2001, Austrobaileya 6(1)) is a stinker of a thing to decipher, but to my eye, just going on his leaf shapes it looks like C. erubescens s. str. (distribution = coastal and sub-coastal areas from Sydney to Rockhampton). The flowers are markedly smaller (17mm) and paler (nearly white) than the angustissimus I'm more familiar with from the Monaro and assorted secondary grasslands in the Bega Valley, and this is the 3rd time I've run across it - others close to Bega, suggesting maybe exotic, but the toothed leaf margin and hairiness lets out *C. arvensis. This was right on the highway verge, so exotic is not out of the question for this plant. It's unusually robust too; I think the whole mass of it may be a single plant.

This is as common as mud in Canberra. I recognised it on sight. Plantnet has a comment that a later paper rejects the subspecies. I presume that is why there are no subspecies on the list. The leaves in this species are highly variable and you have to be lucky enoughto find really basal leaves to find ‘typical’ leaf shape with several lobes. I checked my key about what species of Convolvulus are present on the south coast. Angustissimus is the only native. The introduced arvensis is quite different, with usually white flowers, most records of it in the Sydney area.

Hmm, these flowers are damn-near white and the plant is amazingly robust. See Max's sighting from today (would not have generated an email as he self-confirmed it) for a more typical angustissimus from down here. But we can leave it as that for the time being if you like, until the RBG pronounces. In my experience with angustissimus the leaves are quite variable in shape from the base of the stems to the tip, whereas with this thing they are all exactly the same, just smaller heading in the newer growth.

Perhaps you should send the bright pink version upmto Sydney too. The Canberra version is different again, with washed out flowers, often nearly white, and is a scrappy little plant that has usually lost its basal leaves and only retains one or too practically lobeless upper stem leaves. It is as tough as old boots. I have seen it on a heavily trodden footpath opposite the Belconnen markets.

Yeah, OK, I'll grab a bit of the bright pink one at the next opportunity. I wish the key in the 2001 paper was a bit less impenetrable. I've been happy to just rely on distribution for an ID, but when we've got two such obviously different looking plants where there should only be one species, that won't work any more.

You are right. Let’s see what Sydney says.
