Ludwigia sp2 (?) ID Hooghly 16\/9\/12 SK3:<\/a> 6 images.<\/p>\n
Found this wild herb beside my home today.<\/div>\n
Species : UNKNOWN<\/div>\n
Habit & Habitat : small wild herb, less than 1 foot tall, stem branched, softly angular and clearly winged<\/font><\/div>\n
Date : 16\/9\/12, 10.43 a.m.<\/font><\/div>\n
Place : Hooghly<\/font><\/p>\n
\n<\/div>\n<\/div>\n
This species is closely allied to Ludwigia hyssopifolia<\/i> (G. Don) Exell., having only petals.<\/p>\n
But your specimen with 5 lobes.<\/div>\n
Ludwigia hyssopifolia:<\/b> <\/i>Herbs; branchlets angled or winged. Leaves 2.5-5 x 1-2 cm, elliptic-lanceolate, base cuneate, apex gradually acute to acuminate, glabrous, membranous; petiole to 1 cm long. Flowers solitary, axillary. Calyx tube narrow; lobes 4, c. 3 mm long, lanceolate, persistent. Petals 4, obovate, yellow. Stamens 8; filaments unequal. Ovary 4-celled; ovules many; stigma 4-lobed. Capsule c. 2 cm long, linear, terete, 8-ribbed. Seeds dimorphic, uniseriate and embedded in endocarp below and pluriseriate and free above.<\/font><\/div>\n
Please compare with this species.<\/font><\/p>\n
\n<\/div>\n<\/div>\n
\n
This 5 petal flower is an exception, there was only this flower when i recorded the attached pictures. However, later i noted that all flowers of the same winged species have four petals. And this is very common in moist land, leaves and base of the stem sometimes red tinged.<\/font><\/div>\n
I have another plant, posted in June ’12 (https:\/\/groups.google.com\/d\/topic\/indiantreepix\/J3TAWywxx5k\/discussion<\/font><\/a>), and i think that species is also the same as this one.<\/div>\n
Thank you very much for the ID.<\/p>\n

<\/span><\/span>After a relook at this post i think that i may be wrong, this species may not be the same as in my earlier post, titled “Ludwigia prostrata<\/i>” at – https:\/\/groups.google.com\/forum\/#!topic\/indiantreepix\/J3TAWywxx5k\/discussion<\/font><\/a><\/div>\n

found a ref where a line drawing sort of looks different from Surajit’s flower… look at it … and tell me please… http:\/\/www.wssa.net\/Weeds\/Invasive\/FactSheets\/Ludwigia%20prostrata.pdf<\/font><\/a><\/p>\n

Please refer the following links.<\/p>\n

Thank you very much for those reference. What i learn is –<\/div>\n
1. 4-winged stem with 4 stamens = L. prostrata<\/i><\/font><\/div>\n
2. 4-angled capsule = L. prostrata<\/i><\/font><\/div>\n
3. glabrous similar plant = L. perennis<\/i><\/font>
<\/i><\/div>\n
Since i didn’t take any petal or sepal measurement, neither have any picture of capsule, i take it simply as Ludwigia sp.<\/p>\n
