Which Mussaeda ?


Try to match the sepals in the comparative images.

Thank you …! Mussaenda treutleri Stapf

Recently seen in Sikkim.

Is it the same …

Yes, it is.

Where are the additional image ?

I also agree with … for Mussaenda treutleri as per
Here are the keys between two closely related species from Flora of China:
5 (4) Stems sericeous with appressed indument; stipules 5-8 × 4-5 mm; calyx lobes 4-11 mm. 19 M. macrophylla
+ Stems villous or hirsute with widely spreading trichomes; stipules 7-10 × 6-12 mm; calyx lobes 7-18 mm. 29 M. treutleri

Images in Flowers of India looks different and may be of some other species.


There seems to be some discrepancy in the description of Mussaenda treutleri at FOC and elsewhere.
According to Bhutan Biodiversity Portal, the sepals of Mussaenda treutleri are described as:
Calyx lobes filiform, tappering from base, 4-8 x 1mm, pilose. Corolla tube 1.6-3.2cm, distinctly widened upwards, sparsely pilose;
sepals of Mussaenda macrophylla are described as
Calyx lobes oblong oblanceolate or oblong elliptic, tappering from middle, 7-15 x 1-3mm, pilose. Corolla tube 2-2.8cm, pilose upwards
At India Biodiversity Portal, the calyx lobes of M. treutleri are described as
Calyx lobes to 1 cm long, linear-lanceolate
 I differentiated the two species based on the length of sepals compared to that of flower-tube. Going by the above description, the sepals of Mussaenda treutleriare much smaller than the flower-tube and very narrow. Sepals of M. macrophylla are larger (less than about half the flower-tube) and broader.
 Based on the above, I would assume that this plant is Mussaenda macrophylla.

FOC described sepals of M. treutleri as “lobes lanceolate, ligulate, or oblanceolate, 7-18 × 3-4 mm” 1.8 cm sepal length looks much larger than that in the other two descriptions.


Thanks, … To me … plant matches with illustration at
Also matches with the keys between two closely related species from Flora of China:
5 (4) Stems sericeous with appressed indument; stipules 5-8 × 4-5 mm; calyx lobes 4-11 mm. 19 M. macrophylla
+ Stems villous or hirsute with widely spreading trichomes; stipules 7-10 × 6-12 mm; calyx lobes 7-18 mm. 29 M. treutleri
From the keys, it is evident that hairs on stem play a key role in differentiating these two closely related species. Here the stem is clearly not sericeous with appressed indument. It appears to be villous.
Going through Flora of Bhutan also supports this as calyx lobes appear to be closer to filiform and tapering from the base rather than oblong oblanceolate or oblong elliptic, tappering from middle. Length of the calyx lobes and corolla tube seems to be quite variable as per the measurement given- thus there co-relation may not be correct.
Mussaenda macrophylla is different as per high resolution specimen and other posts by …:

Flora of China further states “This species is similar to Mussaenda macrophylla, and in the protologue M. treutleri was explicitly separated from plants commonly called M. macrophylla, both in the wild and in cultivation; in fact, the protologue noted that M. treutleri was already widely distributed in cultivation at that time incorrectly under the other name. Mussaenda treutleri subsequently has apparently still been confused with or combined with M. macrophylla, including by recent authors (e.g., Springate et al., Fl. Bhutan 2(2): 783. 1999). Mussaenda treutleri is here circumscribed somewhat differently than by H. H. Hsue and H. Wu (in FRPS 71(1): 301. 1999): the plants from montane Yunnan and adjacent regions with broad, generally persistent stipules were separated by Stapf from M. macrophylla and included in M. treutleri, and this distinction is followed here.”


Thank you …! …: Mussaenda pubescens and its SYN. are not listed in Nepal.

Mussaenda macrophylla, the white bracts are attractive even from a distance in the forest.


…, does this plant have a climbing tendency ?


It was a shrub …, if i remember correctly.


Shouldn’t this be Mussaenda glabra? I would like to be enlightened about the differences.


Nice set of Pics … I had come across this Mussaenda sp. growing wild in the forest cover of Matheran – Prabal valley. Attching few photographs of the same. Attachments (4)


… plant seems to be different from …


…, the query because, had found similar species of Mussaenda at Prabal Machi (near Panvel, Maharashtra) … 11JUL10 8:28AM

Could see those white bracts on the canopy of a small tree (this tree was out of reach, so could not get nearer).
A photo (very poor quality, attached) shows the sighting, leading me to wonder whether any Mussaenda “climbs”.
Climb may not be appropriate, nor straggle … very loosely growing with sturdy support.
The habitat is a slope, and it is possible that the Mussaenda plant could be rooted somewhere higher up on the ground, and may have sent its slender branches among the tree branches … the apparent sight could have misled me. Attachments (1)


…, I will verify the id once again. My id has reference to the short calyx lobes. http://www.iaat.org.in/Rheedea19_53-57.pdf
M. glabra looks different from my plant as well as that of …: http://www.flickr.com/photos/ncmls/4326249184/ ; flowersofindia 
… plants (beautiful pictures!) have longer calyx lobes and pubescent corolla. So both are different species as you said.
…, i understand that there are some ‘climbing’ (straggling) shrubs in Mussaenda, for e.g. M. pubescens. Your plant looks like a straggling shrub to me too. So this thread contains three different species i hope. [I am unable to give a clearer picture as i dont have access to Indian Floras at present]. 

If not wrong, my plant could be same as …, on account of location.
My plant found near Prabal Machi (Panvel side) … … could be Matheran side.


I had noticed this plant both on Panvel side as well as on matheran side. Photos shared by me were from Matheran side.


I am coming back to this post after several year, after gaining some clarity on the Mussaenda species of the Himalayas. This indeed should be Mussaenda macrophylla, as … had originally identified. The roundish petals and relatively large hairy sepals are characteristic features of this species. Mussaenda glabra Vahl, on the other hand, is pretty much a hairless plant (as the name itself suggests), and has very small sepals:
Mussaenda glabra Flower tube: 1.3-1.8 cm, Sepal size: 1-4 mm
Mussaenda macrophylla– Flower tube: 2.-2.5 cm, Sepal size: 1.2-2 cm


I think it may be Mussaenda treutleri as per discussion under thread.
