It is Schefflera arbiricola, an ornamental plant.
I have also clicked it at YADVINDRA GARDEN, Pinjaur, Haryana, last year
As per link below Schefflera arbiricola is not listed in Nepal. 
As such, I am a bit confused.
If it is the same plant for sure it could be a new species for Nepal. 

I had thought it to be cultivated. Thanks for species ID.
It is from the forest !
Can I firstly advise that members should NOT automatically TRUST the identification of postings on blogs on the internet.  They should be SCEPTICAL.  Few who grow plants are experts on plant identification.
Whether or not the US BlogSpot here has correctly named the plant correctly as Schefflera arboricola (note the correct spelling of the species name), it is UNLIKELY that one can RELIABLY arrive an identification by "matching" a few general images taken in India or Nepal with one or two general images on a web-site.
Schefflera is a VERY large genus and thus will have a number of closely-related species, which will be difficult to tell apart.
S.arboricola is NOT known as a native of Nepal.  THUS, it will ONLY be CULTIVATED or at most NATURALISED in Nepal.  IF, it actually is the proposed species.
IF the plant photographed in Nepal is a genuinely 'wild' specimen (this can be difficult to decide when close to habitation), then it is highly unlikely to be a species known as a native only to Taiwan and Hainan (according to Wiki).
I do not have the time to familiarise myself with the genus Schefflera, so UNLESS we have someone with specialist knowledge of the genus or KNOW about any Scheffleras IMPORTED into Nepal for ornamental merit, then PROBABLE, assuming it does belong to the genus Schefflera, it is LIKELY to be a variant of one of the three species known to occur in Nepal.

Schefflera venulosa

Is it the same. I think number of leaves and flower colour differ.
Schefflera venulosa

Schefflera venulosa (Wight & Arn.) Harms

if it is a tree then it should be Schefflera elata (Buch.-Ham. ex D. Don) Harms whereas Schefflera venulosa is climbing shrub.

Inflorescence pattern looks different from Schefflera elata as per GBIF and does not match.
Also looks different from Schefflera venulosa

Only 3 sp. in Nepal so far.

As per current situation in CoL, Schefflera venulosa (Wight & Arn.) Harms does not have any distribution in Nepal (also not reported in flora of Bhutan). While Schefflera roxburghii Gamble (Schefflera venulosa var. roxburghii (Gamble) K.K.Khanna) is reported from Nepal.
To me appears close to Schefflera roxburghii Gamble as per GBIF specimens as below:
