Small latin-american vine and weeds

9 years ago

Hi everybody,

1-Any clue on this small vine, two three feets long at most, twisting type, two or three small winged seeds per fructification, no fragrance. Grows in arid rocky slopes mostly. I wish to cultivate ir so it would be more abundant, but wildplants rarely like to be moved.

2- This one reminds me a Gaura, up to six feet tall weed, variable apearence, some redisk (kind of virus or crestation I presume) very prolific with seeds resembling rye, very easy to collect.

3-A local ipomoea, grows in arid soild, tubers form inside the cracks of rocks, favorite food of some sort of orange spotted ladybug, adults and larvae leaves very little of the plant. Flower with subtle color very difficult to capture, usually closing when I wake up.

Thanks. Paul

Number 1 is some type of Stigmaphyllon - I have a vine with similar flowers here (australia) but mine has different leaves and is fine and straggly. Here's the Wiki link and you might have to google up images to find your variety

No 3 I'm wondering if similar to Ipomoea pes-caprae - although it's usually found along dunes, it has a similar flower and leaf. Mind you there are so many ipomoea and convolvulus and sometimes only small differences

I agree that 2 must be a gaura, but I have no idea which. They're said to be native only to North America.

I think #1 may be Janusia guaranitica, which is in the Malpghiaceae family, as are the Stigmaphyllon.

Perhaps the Gaura travelled with cattlefeed/hay or by similar means.
Is the area used by farmers?

There are lots of examples of seeds travelling, mostly as stowewaways, in wool, with grain, in bird feed.

I just googled Gaura species and came across about 8 others, (sorry, no pics with that link),
That is an interesting find,

That's a good point about the animal feed, linaria. I was trying various searches earlier and came across a mention of gaura seed as a contaminant in grain or maybe feed crops. Unfortunately I can't find it now.

G. parviflora has the smaller flowers, and can be 6' tall:

Oenothera curtiflora (newer name of Gaura parviflora) is listed as naturalized in Argentina.
