Largeflower Pink-Sorrel Oxalis debilis

Description

I've gotten quite a lesson in pink-flowered Oxalises trying to ID these plants in the creek corridor near Salton Drive. Prompted by @alisonnorthup, I finally made the effort to document the crap out of these plants, and the verdict is Oxalis debilis. There are about a dozen clusters/colonies of plants along a 100 yard stretch of the creek, growing in loose sandy silt near the creek bank. I prepared a detailed description of these plants (below). The eFloras.org key for the genus is here:
http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=123464
and the species account for O. debilis is here:
http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250031756
Here's the longwinded documentation for my plants:

GROWTH HABIT: Plants acaulous but clone-forming, 10 to 20 cm tall; individual clusters or colonies 10 to 80 cm across. BULBS present, creamy white or pale yellow, clustered in older specimens, to 2 cm tall and wide; bulb scales dark brown, conspicuously 3-nerved; many small crowded bulblets present on older plants, bulblets typically 3 to 5 mm diameter after calving; tap root present on one mature bulb, 5 mm diameter at base, about 4 to 6 cm long (broken during extraction); fibrous roots moderately numerous, rhizomes and tubers absent. LEAVES: Petioles 8 to 15 cm, glabrous to thinly pilose; leaflets green, slightly paler below, broadly oval to obcordate, to 25 mm long, 30 mm wide, notched 1/8 to 1/4 of depth, lobes rounded; venation slightly impressed above, 2 secondary veins evident on each side of primary vein on underside; base of leaflets with dense tuft of hairs, both surfaces of leaflets sparsely strigose to hirsute (need hand lens); single line of inconspicuous oxalate crystals along outer margin, more visible from the underside, few or none interior to the margin (again, need hand lens).
FLOWERS: Primary scapes slightly shorter to slightly longer than longer petioles, glabrous (?); flowers 4 to 8 (December specimen) in a simple to slightly branched cyme; pedicels to 3 cm long; sepals 5 to 6 mm, lanceolate, acute, green with a narrow hyaline margin and two conspicuous convergent orange tubercles at apex; petals oblong-oblanceolate, somewhat oblique on the bluntly rounded apex, 12 to 15 mm long, to 5 mm wide, pink with conspicuous purple veination in inner half, the petals and venation becoming green near base, stamens 10 in two series, anthers white, filaments green, short hispid; styles 5, green, appearing to be shallowly bifid at apex, short hispid on margins or outer side (?).

Description

Not sure of identification anymore. The name used here has been applied to plants like this found sparingly naturalized in the Auckland Region (and also sold as an 'edible' Asian herb in local markets). The inflorescences - as a rule - are not branched. However, this population which I have kept under observation for five or so years (see for example https://inaturalist.nz/observations/9108341 and https://inaturalist.nz/observations/4662301), has this year, started to produce branched infloresences - so matching plants called H. bonariensis. Interested to know what the correct name for this Hydrocotyle is.

In a lawn. I'd thought this was pink-eyed grass at first glance, but it looks a lot like oxalis, doesn't it? I couldn't find any leaves to confirm, though, and didn't want to spend too much time rooting around in a stranger's front lawn.

Edit: just noticed that there are some oxalis leaves visible under the leftmost flower clump.

The culmination of my hiking and birding efforts in SoCal in June 1974 was the discovery of a nesting pair of Spotted Owls in Trabuco Canyon. A day after the initial discovery, I invited raptor bander Pete Bloom to accompany me back to the spot to attempt to band the birds. Pete was successful at capturing and banding both adults and the single fledgling. Here is some documentation of that effort, including a John Denver-ish image of me at the time with the fledgling and Pete Bloom holding one of the adults. I also include an image of the canyon as it looked that day where Pete set up the small trap to capture the owls.
