Mazus pumilus looks similar to M. surculosus, but the orange stripes on the lower lip are longer in latter. In addition the species can be differentiated as under:

M. surculosus: Perennials, up to 8 cm tall, stem with long white hairs; basal leaves forming a rosette present at flowering time; flowers almost from base of raceme, lax; calyx lobes 1/3 as long as calyx, broadly ovate with obtuse to subacute tip; middle lobe of lower lip longer than lateral lobes; lobes of upper lip suborbicular; capsule ovoid
.
Branched herbs, to 10 cm tall; stems hispid. Lower leaves opposite and closely packed, to 5 x 2 cm, obovate, obtuse, crenate to serrate, upper ones alternate, smaller. Flower few, in terminal racemes; pedicels 10 mm long, slender, woody, erect; calyx campanulate, 6 mm long, divided to the middle, lobes triangular to ovate, leafy; corolla pale violet with yellow centre, 2-lipped, upper lip orbicular, lower 3-lobed, midlobe smaller than sidelobes, spreading; stamens 4, didynamous, anthers divaricate; style short, stigma 2-lamellate.

Mazus pumilus (Burm. f.) Steenis from Hooghly: This seems to be the plant which is also known as Mazus japonicus (Thunb.) Kuntze.
Species : Mazus pumilus (Burm. f.) Steenis
H & H : wild small herb in a rural kitchen drain
Date : 9/11/12, 1.50 p.m.
Place : Hooghly You are right … the pics are, as usual, very beautiful…     Mazus? Hooghly 06-01-13 sk: Species : UNKNOWN
H & H : less than 1 ft, prostrate-erect herb found in paddy-field
Date : 6/1/13
Place : Hooghly I think Mazus Now it appears to me that this too can be Mazus pumilus (Burm. f.) Steenis, for FoC informs – “corolla white, purple or blue” and the flowers in this thread can be called creamy-white, instead of yellowish. Very interesting find –
F. I. iii. 97 describes four Columnea species –
(i) C. balsamica R. = “….. capsule long (capsule in this thread is globose)
(ii) C. heterophylla = ” …. floral leave sessile…. a native of Bengal, in wet places, during dry season
(iii) C. tomentosa – “…… a native of Bengal, appearing during the cool season
(iv) C. minuta – ” …. annual spreading, four-sided” ,,,, maybe the one at – Oswaldasia
F. B. I. iv. 259., while describing M. rugosus Lour. informs, “……. Roxburgh’s Columnea tomentosa, referred here by Bentham, can hardly be this.”

M. pumilus (Burm.f.) Steenis is a common species in Pantnagar. Here it blooms almost throughout the year.
Photographed in Pantnagar Uttarakhand.
Nice Photographs … I hope Majus was a typographic error. It should be Mazus pumilus. Very nice … Both M.pumilus and M.surculosus are very close. Both have yellow spots.
Will you please tell us about the differences?

I find it more closer to images at Mazus pumilus (Burm. f.) Steenis compared to those at Mazus surculosus D. Don Majus sp. i cant go further on these pictures. needs a little more details in pics etc. this thread tells you why, by … I guess it is Majus surculosus ! Flower image not clear
Thanks for the feedback.
I looked at … post linked by … and am trying to put down points in favour of M.surculosus.
In favour of M. surculosus:
– stem with long white hairs
– basal leaves forming a rosette at flowering time
– middle lobe of lower lip longer than lateral lobes
– Calyx lobes 1/3rd as long as calyx against Calyx lobes as long as calyx in M pumilus
– Orange marks are longer (I think)
Besides, these pics look different than the ones posted by me earlier.
Would greatly appreciate any comments. Thanks, … Things can be better appriciated if you see all the images in efi site. Yes, it’s … I agree with … Thanks … If I understand your comments correctly, this is M. pumilus.
