Drosera trinervia (Small Sundew)

Notes
Drosera trinervia is a perennial carnivorous plant and can be recognised by its small basal rosettes covered with reddish, sticky, glandular hairs. The palnts are only 50 - 100 mm high and have one or two long, slightly swollen roots. The wedge-shaped laminas (leaf blades) have slightly rounded ends, 10-20 mm long and 4-7 mm wide. The three veins on the underside of the lamina are most noticeable on dead leaves. Petioles (leaf stalks) are absent but stipules are present on either side of the base of the lamina margin. The stipules, in the form of two thin filaments, are inconspicuous and deciduous. The glandular hairs or tentacles are much larger at the top of the lamina than at the base. The lower surface of the lamina is smooth and without hairs (glabrous) or becomes smooth with age (glabrescen). The flowering stalk originates directly from the centre of the plant. The inflorescence can reach up to 100 mm and 2-10 white or, infrequently, mauve to red flowers are borne closely together. The styles on the ovary are fringed at the top. Flowering occurs from August to November. Blackish-brown, ovoid seeds, 0.3 mm long, are formed in the oblong capsule.

Welcome to iNat! Great photos, and obviously you are an expert with ID. You might need to just look for a field that lets you 'Suggest ID' so that it gets labelled correctly. If it doesn't have a label on it, it will sit in the 'unknown' category. Hope this helps!

Hi, thank you! Very much appreciated, no expert. just a very passionate hobbyist, I will see if I can get it fixed. Thanks for the tip, still finding my way around☺️

Erica demissa

lucstrydom commented
I would say E.demissa based on the stoutness of the style.

evieb commented

Ok. Could be E. demissa.
Although key says stigma is simple?
See similar recent posts by Nicky in Kouga;-

Stigma looks capitate to me (in both this and Nicky's obs). Bredenkamp (2019), compiled by S. P. Bester describes E. demissa as having a stoutish style and a peltate-capitate stigma. E. simulans is described as having large, lobed stigma (clavate-capitate).

Interesting. Thanks for that info. That would fit as most of the observations show more than just a 'simple stigma"
I guess the "Southern Cape Erica" key , which refers to a simple stigma in E. demissa - is out of date on that one!.

Muraltia knysnaensis ( Evie seen Herolds Bay West)https://www.inaturalist.org/observations/51076796#activity_comment_a8f46db1-59a9-4468-9ea1-83f877fc21eb

Muraltia knysnaensis
Muraltia knysnaensis
Garden Route Purplegorse
Levyn's description below.
Her drawing shows the leaves as shortly spine tipped, and it fits in all other respects.
Muraltia knysnaensis
An undershrub, 10 — 20 cm. high, branching chiefly near ground level.
Young stems puberulous. Leaves usually solitary, occasionally imper-
fectly fasciculate: the primary 5-0 — 12-0 mm. long, acicular, linear or
sometimes ovate on the flowering branches, ciliate when young, other-
wise glabrous, fiat or channelled above, rounded below: the secondary
much smaller. Bracts 1-0 — 1-3 mm. long, ovate or oblong, concave,
obtuse. Flowers 6-0 — 7-0 mm. long, pink, sessile. Sepals glabrous,
obtuse or sub-acute, apiculate: the outer ovate, concave, non-ciliate or
sparsely ciliate: the inner elliptical, almost flat, ciliate, the apiculus well
developed, about half as long as the side petals. Side petals linear or
lanceolate, longer than the carina, narrowing somewhat abruptly into
an obtuse slender tongue-like tip. Claw of the carina a little shorter
than the limb: the line of attachment of the crest more or less vertical,
of medium length, the width of the crest less than the length of the carina,
the upper and lower lobes somewhat similar. Ovary shortly hairy on the
top, the horns long, very slender: the style slender, the anterior branch
minute, the posterior long and narrow, making an obtuse angle with the
style: the stigma oblique. Capsule ovoid, rough or shortly hairy above,
almost completely hidden by the calyx: the horns slender, as long as or
slightly shorter than the capsule. Seed globose or nearly so, hispidulous,
the caruncle with broad membranous lobes.
M . knysnaensis occurs on dry flats and hill slopes.

Gosh - super to be given all those technical details. Generally so difficult for us "ciizen scientists " to find and access such information.
Many thanks Andrew.

i think we are all intimidated by Muraltias. :). I know I am. I was lucky to find her book online which can be downloaded here: https://archive.org/details/botanysupplement02unse

It makes me feel much more comfortable doing ids.
Matt Fainmann and I are doing a key where I have synthesised the info from Levyns with Cape Plants and put it in a spreadsheet. Matt is doing the wizzardly stuff to turn the spreadsheet into a key which links it to verified obs on i-Nat. It will hopefully be ready quite soon. Once it is up and running he will link it to the other keys which he has moved from I-Spot to here: https://inatkey.herokuapp.com/
Regards
Andrew

Thanks Andrew- good luck .
@knysna_wildflowers
useful info.

knysna_wildflowers commented

Tx - yes - will be a big help. The biggest issue with id of muraltia is that you need the flower detail and the flowers are SMALL. So most photographs are not that useful......

knysna_wildflowers commented

I think M knysnaensis and M ericoides are often mixed - need to find a solid way of distinguishing the two.

andrewm commented

I have looked for differences in the descriptions and there is really not a difference. Perhaps (but not certain) is that knysnaensis seems to have the flowers all the way down the flowering stem, whereas the one and only ericoides I have found here: https://www.inaturalist.org/observations/66476673 has the flowers more at the top.

I have id a few M ericoides in the eastern False Bay area - they seem to have quite a recognisable habit there.....
