Thanks, …  I was wondering about these.


Flora of Arunachal Pradesh- Namdhapa near Miao- Herb 4 for Id- JM:
Wild at Namdhapa near Miao, Arunachal Pradesh in 3rd week of August’10.

Can this be a species of Lindernia (Scrophulariaceae)? may be L. ciliata

I think … is correct.

I think it matches with details as per links of Lindernia ciliata (Colsmann) Pennell (Fringed False PimpernelManipuri: কিহোম মান Kihom Man) of Scrophulariaceae (Dog flower family)
flowersofindia (FOI),

It could be Lindernia antipoda. Flowers here are larger in size.

A few links for Lindernia antipoda:
I am unable to decide between the two right now.

I think the plant is Lindernia antipoda only.

In Lindernia ciliata, leaf blades are sessile or clasping, margins of blades are sharply & deeply serrate, the teeth spreading in to a setaceous tip, Corolla ca 5 mm long.
But in Lindernia antipoda, leaf blades are petioled, elliptic, sharpely serrate, but the teeth not setaceous tipped; Corolla ca 13-15mm long (After, Francis W Pennel, 1943. A second summary of the Scrophulariaceae in New Guinea, Journal of the Arnold Arboretum. 24(3): 250)
Your plant corroborates the characters of L. antipoda.
You may use the following link to download the paper..
flickr (for some images of L.ciliata)

This is not Lindernia ciliata, for sure as … pointed out, L. ciliata has sessile leaves and corolla is white with pink throat.
I think it is the same species that I had posted few days back at efi thread.
The leaves of L antipoda is elliptic obovate and is about 2.5cm. Here, if my assumption is correct, the leaves are more than 3cm long.
Further, the key in The flora of the Tamil Nadu Carnatic (page 1083) says that calyx margin serrulate in L antipoda
Calyx margin entire for Lindernia ruellioides
I think this is Lindernia ruellioides even the one that posted on August 2. (The flora of the Tamil Nadu Carnatic (1983), page 1092)

Lindernia antipoda

Further feedback as per another thread.
“This is not L. antipoda the leaves in L. antipoda is not so broader, flower is also slightly different.
Further the id in the given link is also not conclusive as the plant given in that thread and my thread (this thread) looks similar.

Could this be Lindernia serrata of Scrophulariaceae family.

… probably this is not Lindernia serrata based on the leaf shape and attachment

Leaf shape, according to Gamble, is oblong.

Could this be Lindernia antipoda?? See an earlier post

My choice is also Lindernia antipoda (L.) Alston

Sapporting Dr …

This is not L. antipoda the leaves in L. antipoda is not so broader, flower is also slightly different. Further the id in the given link is also not conclusive as the plant given in that thread and my thread (this thread) looks similar.
