I'd like to get a second opinion about the ''Dictyospermum montanum'' (Commelinaceae)  photographed by Vinayaraj and put on Wikicommons (https://sv.wikipedia.org/wiki/Dictyospermum#/media) and on Indiabiodiversity.org (https://indiabiodiversity.org/species/show/243879). Is this actually Dictyospermum montanum or is it rather Pollia secundiflora?
The inflorescences and flowers on Vinayaraj's pictures are just like the Pollia secundiflora that I photographed in Sri Lanka. It was easy to identify due to the large dark blue berries that are characteristic of this species and the brown hooked hairs on the spike, I found it as a large group of 1 meter high plants in a clearing in a lowland dry zone jungle. See pictures below. It is described on Flowers of India at https://www.flowersofindia.net/catalog/slides/Three-Stamen%20Pollia.html.
The inflorescences are described as: ''White flowers borne in a spike longer than distal leaves, more than 20 cm. The spike is densely covered with brown-yellow hooked hairs, ,,, . Stamens are 6, with 3 fertile ones and 3 staminodes. Fruit is round, about 6 mm in diameter'.
I also photographed Dictyospermum montanum in a swampy shady area in a mountain forest in Sri Lanka and it is the same as the one on the photographs of this plant on Eflora of India (https://sites.google.com/site/efloraofindia/species/a---l/cl/commelinaceae/dictyospermum/dictyospermum-montanum) and Flowers of India (https://www.flowersofindia.net/catalog/slides/Mountain%20Dayflower.html).
The  Dictyospermum montanum is described as having tiny flowers on the end of panicles.
Several herbarium specimens of Dictyospermum montanum and Pollia secundiflora can be viewed at
and
(Specimens can be viewed individually by clicking on them, and then in greater detail by clicking on them again.)
The inflorescences of the plant ... and I photographed matches the specimens of Pollia secundiflora.

Thanks, ..., for the detailed and comprehensive post. 
I am agreed with … view, both (https://sv.wikipedia.org/wiki/Dictyospermum#/media and https://indiabiodiversity.org/species/show/243879) are nothing but a Pollia secundiflora
