Oxalis corniculata- Creeping Woodsorrel?

[J.M. Garg]

On 16/8/08 in Talakona forest, AP near Tirupati. I hope the Id is correct.

 

Here are some extracts from Wikipedia link:http://en.wikipedia.org/wiki/Oxalis_corniculata

Creeping Woodsorrel (Oxalis corniculata) [Not to be confused with Yellow Woodsorrel, or Oxalis stricta], is a somewhat delicate-appearing, low-growing, herbaceous plant in the family Oxalidaceae. It has a narrow, creeping stem that readily roots at the nodes. The trifoliate leaves are subdivided into three rounded leaflets and resemble a clover in shape. Some varieties have green leaves, while others have purple leaves, like the Oxalis corniculata var. atropurpurea shown here. The leaves have inconspicuous stipules at the base of each petioles.

The fruit is a narrow, cylindrical capsule, 1 to 2 cm long and noteworthy for its explosive discharge of the contained, 1 mm long seeds.

This species is cosmopolitan in its distribution, and its place of origin is unknown. It is regarded as weed in gardens,^[1] agricultural fields, and lawns.^{[citation needed]}

The leaves of wood sorrel are quite edible, with a tangy taste. A drink can be made by infusing the leaves in hot water for about 10 minutes, sweetening and then chilling.^[2] The entire plant is rich in Vitamin C. Although any wood sorrel is safe in low dosages, it must be noted that if eaten in large quantities over a length of time it can inhibit calcium absorption by the body.^[2]

Hello,


In my garden in Bangalore I have found similar variety, but with light violate color flowers, the leaves bigger in size and the leaves shoot directly from the bottom, with no "branches". Can it be Oxalis barrelieri: Lavender Sorrel (http://en.wikipedia.org/wiki/Oxalis_barrelieri) ?

Regards,
Vaishali.

Appears to be Oxalis dehradunensis. From Indiantreepix Database:

Oxalis dehradunensis

Oxalidaceae

Dun Ambushi

22/6/08- abundant in some areas of Panchgani, Maharashtra.

Oxalis dehradunensis - indiantreepix | Google Groups

I think if one checks Indiantreepix Database, one will get lot of clues & lot of Ids can be sorted out.

Taking this as Oxalis latifolia subsp. latifolia for the time being, as per discussions at Balsaminaceae, Geraniaceae and Oxalidaceae Week: Oxalidaceae- The fate of Oxalis dehradunensis- it is Oxalis intermedia-GS-4

[JM Garg]

This should be Oxalis dehradunensis (Introduced) as per discussions at efi thread.
