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. Capsule 3 x 3 mm, oblong; seeds oblong, rugose, brown.

Mazus pumilus (Burm. f.) Steenis from Hooghly:

This seems to be the plant which is also known as Mazus japonicus (Thunb.) Kuntze.

You are right … the pics are, as usual, very beautiful…

Mazus? Hooghly 06-01-13 sk: This is a small herb with yellowish flower. Don’t know if it is Mazus or Lindernia or some other.

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 – http://www.oswaldasia.org/species/l/linpu/linpu_02.jpg
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?

This should be Mazus pumilus


major weed of wheat fields and other grains

may be becoming resistant to herbicides

that would make it a  major concern worldwide

I wonder if there are natural predators for this and similar weeds in India?

This may be Mazus pumilus or any other species of Mazus.


it is Majus species. family Scrophulariaceae


Mazus species so far in efi 


Yes, it is Mazus pumilus, deformed or mutilated specimen of M. pumilus are often found in paddy fields, the cause maybe use of insecticides/herbicides/pesticides/inorganic manure etc.

Another wild herb seen in Oct,18.

Please look at this one: Mazus pumilus (Burm. f.) Steenis (Mazaceae) Japanese Mazus



Saw this along the Govindghat – Ghangaria trail, Uttarakhand in Aug 2018.
IDed based on efi pics. Requested to kindly validate.

Markings look a bit different.


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.

Corolla markings are very important.

Leaves and other things looks very confusing


Yes, it’s …


I agree with …


Thanks … If I understand your comments correctly, this is M. pumilus.
