VoF Week :: DV :: 04 AUG 12 – 1148 :: interesting buds along Ghangaria – Govind Ghat trail: 4 AUG 12
Ghangaria – Govind Ghat trail 10160 – 5800 ft

Habitat: mountain slope
Habit: herb, about 1 m high (not sure; out of access); the cluster of ¿ buds ? interested me … size: 1 – 1.5 cm (not sure).
… will be happy to get hint of genus.


My perception….this looks like Leptodermis lanceolata…..a juvenile form..may be I am wrong…..


I think … is correct, Leptodermis lanceolata, we had seen plenty of such on Chakrata trip.



… has posted one Leptodermis sp. I too had seen this at Joshimath and also at Govindghat-Ghangaria route.
The plant posted here is from Joshimath.
Family: Rubiaceae
Date/Time: 06-08-2012 / 11:50AM
Habitat: Wild
Plant habit: Shrub.
Enclosing some cropped images also.


Yes Leptodermis lanceolata

VoF Week :: DV :: 04 AUG 12 – 1045 :: white flowered slant herb along Ghangaria – Govind Ghat trail: AUG 12
Ghangaria – Govind Ghat trailabout 7000 ft
Habitat: mountain slope
Habit: herb, about 1 m high, growing slant; flower about 8 – 10 mm across


I hope Leptodermis lanceolata


I would guess Leptodermis kumaonensis but detailed features need to be checked to distinguish it from Leptodermis lanceolata


I too had seen this plant at 2 places, one along Govindghat-Ghangaria trail and other just before Joshimath. Will share the photographs by evening..


Would be interesting to know the differences between the two species but judging from comparison with plants uploaded on FOI it seems to match more with mine Leptodermis lanceolata from Chakrata.

You are right. It is Leptodermis lanceolata. In Leptodermis lanceolata, flowers are borne in cymes at the end of stem, or on lateral branches. In Leptodermis kumaonensis, they are almost fascicled on the stem. Moreover, flowers are white in Leptodermis lanceolata, whereas they are white or pink, fading to purple in Leptodermis kumaonensis. These are the observations of a layman. 🙂


You are not a layman, much more accomplished than many of us (no aspersions on fellow taxonomists). Your knowledge of Indian Flora is unparalleled. Plus your website is something every botanist and nature lover should thank you for. Truly a great contribution.
If any member has access to original description of L. kumaonensis, kindly forward it, as it may help further. I thought we had seen some plants with reddish flowers also in Chakrata.


Thank you for your flattering words. Here is a description of Leptodermis kumaonensis

Rubiaceae Week: Spermadictyon suaveolens Roxb. from Chakrata area:  Spermadictyon suaveolens Roxb., Pl. Coromandel. 3: 32. 1815.

syn: Hamiltonia suaveolens (Roxb.) Roxb.
Erect shrub with spreading branches; leaves opposite, fetid when crushed, ovate-lanceolate to elliptic, 10-20 cm long, roughly pubescent especially beneath along veins; stipules triangular, 2-4 mm long; petiole 12-18 mm long; flowers blue-lilac to white, 12-16 mm long, in small bracteate clusters forming terminal up to 25 cm long panicles; calyx hairy with up to 2 mm long lobes; corolla somewhat funnel shaped, tube 8-12 mm long, lobes spreading 2-3 mm long; capsule ovoid, 3-4 mm long.
Common along roadsides along Mussoorie Chakrata road and in Chakrata. Photographed in September


If I am not wrong you have uploaded a different plant, of course Rubiaceae, but should not be Spermadictyon


I would be happy if correct identification is found.


Yes Sir, I have also gone through the thread, after I mailed you. I usually hesitate to question your identification (and everybody should..). This I did because I remember that old thread, my identification of the same was not agreed, and for that I no longer believed this plant to be S. suaveolens..
The reason of my previous identification was that I had collected the specimen from Morni Hills and got this identified as Spermadictyon suaveolens… now I have to recheck my herbarium collection.. what has gone wrong.. If this turns out to be S. suaveolens then is it not that the plant with pale blue flowers… I had uploaded two days ago is also suspicious then.
Hope to get clues, you have the keys to many such questions


It is turning out to be interesting. Strobilanthes pentestemonoides (syn: Goldfussia pentestemonoides) seems to be a different plant with flowers pale purple or violet (never white) and larger in size with (about 4 cm long) and corolla tube nearly 12 mm wide above, also calyx is deeply divided and glandular hairy, none of which are found in our plant also 4-5 linear stigma lobes are clearly seen in my photograph. http://davesgarden.com/guides/pf/showimage/217590/

Yes my plant resembles … plant which also does not resemble photographs in above links.


I seem to be coming close to resolving this. I was all along confused about a semitubular structure outside the calyx seen in photographs which I have cropped and uploading here. They seem to be two bracts which are partially united towards base.
I feel my above plant is as such Leptodermis lanceolata Wall.
Please confirm.


Interestingly we are not only ones to get confused. Famous author D. Don also got confused. Following is listed as one of the synonyms of Leptodermis lanceolata in eFl Pakistan

Hamiltonia suaveolens auct. non Roxb.; D. Don 


Leptodermis lanceolata Wall. in Roxb., Fl. Ind. ed. Carey & Wall. 2: 191. 1824 syn: Hamiltonia fruticosa D. Don; Hamiltonia suaveolens auct. non Roxb.; D. Don
Erect shrub with spreading branches, up to 2.8 m tall, glabrous; leaves opposite, fetid when crushed, lanceolate to ovate-elliptic, 2-10 cm long, pubescent especially beneath; stipules small, appressed, acute; petiole 3-6 mm long; flowers white, sometimes tinged with purple, 12-18 mm long, in small bracteate clusters forming terminal large panicles; each flower enclosed by two partially confluent bracts; calyx lobes small, ciliate; corolla somewhat funnel shaped, tube 8-10 mm long, lobes spreading; style long 5 branched at tip; capsule cylindric, 7-8 mm long, splitting into four valves.
Common along roadsides along Mussoorie Chakrata road and in Chakrata. Photographed in September


Thank you for the clarifications sir…
My contribution of the same taken in August last year from Kalatope Sanctuary…


Thanks … for such clear photographs. The bracts enveloping the calyx are clearly visible in your photograph no 2

White flowered Mirabilis jalapa?


This is not M.jalaapa. I have plenty around my house.  I will post the pictures shortly.


This plant looks very close to Spermadictyon suaveolens Syn. Hamiltonia suaveolens A Rubiaceae plant..


This may be a climber twining on a shrub. If the leaves are less than 5 cm and flowers less than 1 cm then this can be Jacquemontia paniculata of Convolvulaceae.


This looks like Goldfussia pentastemonoides of Family Acanthaceae


I am tending to agree that the plant in question is not in Convolvulaceae as the leaves appear to be in opposite arrangement and all plants in Convolvulaceae have alternate arrangement.


This cant be Goldfussia! Pl follow this link.. http://mail.ssps.tpc.edu.tw/~yafen/flora/acanthaceae/goldfussia%20for…


Thanks for forwarding me this useful literature. Yes! I am also not convinced with S. penstemonoides
Even there is a little ambiguity in the name. (Ref: Fl. China). 
Strobilanthes penstemonoides (Nees) T. Anderson, J. Linn. Soc., Bot. 9: 477. 1867.
Goldfussia penstemonoides Nees in Wallich, Pl. Asiat. Rar. 3: 88. 1832 [“pentastemonoides“]; G. flexuosa Nees; Ruellia capitata Buchanan-Hamilton ex D. Don. 
Hope we’ll get the correct identity soon.  


The specific epithet ‘penstemonoides ‘ should be valid because it is based on Ruellia penstemonoides from Wallich Catalog.. But not sure of the id yet. 


Please check a previous thread on Spermadictyon suaveolens @
https://groups.google.com/group/indiantreepix/browse_thread/thread/dc…
I think this is indeed a Rubiaceae species, though I am not sure about the species. 
My thoughts are based on opposite leaves, interpetiolar stipules and inferior ovary with persistent calyx.


Leptodermis lanceolata Wall. Vernacular name in Uttarakhand: Padera, Padar.

If we go by the keys at link (it should be Leptodermis kumaonensis as corolla seems to be pubescent outside). … may further check with original images. 


After going through all threads, I feel it is Leptodermis lanceolata only & does not match with images of Leptodermis kumaonensis in efi thread.

I have a feeling, I have seen this somewhere, but cannot place it.

Requested to please provide ID.


These resemble Leptodermis lanceolata. Kindly validate.


Yes, you are right …
