May I know this marshy prostrate weed found near the coast is a species of Suaeda or some other. It is fleshy, with 5 sepals, petals and stamens; a large disk is +, the ovary is submerged in the disk.
Pls help me in the identification.


Interesting find. Looking at these photographs i remembered seeing a prostrate herb (Sesuvium portulacastrum) with reddish stem and thick, fleshy leaves at Alibag (Maharashtra) near Sea shore.


It is not Sesuvium portulacastrum, see the image attached; I am sure; because i had examined the live specimen, the leaves measure less than 0.6cm, thick and succulent, the flowers are 5 merous, sepals
5, green, united, triangular; petals-5, free, much shorter than sepals, (minute), white, stamens 5, included, large disk pinkish, in which ovary is enclosed, style short, stigma capitate.


It looks like Sesuvium portulacastrum, Aizoaceae

Please identify – Trianthema sp. or Portulacaceae sp? : Attachments (3).   5 posts by 4 authors.
Please help to identify the semi-succulent prostrate plant collected from the coast of Parangipettai, Tamil Nadu recently. There’re no field data except the images available. Is this obscure plant is Trianthema sp.? or
Portulacaceae sp? please find attached the images for your kind perusal


Atleast me cannot go for Trianthema…nearest I can guess is any Suaeda sp.. but I can be absolutely wrong in both regards..


If style 1…. it could be… Trianthema triquetra


I think it appears close to images at Trianthema triquetra Rottler & Willd.


yes it is Trianthema triquetra


Yes … it is Trianthema triquetra.
