altitude Lyto weddell & insigne at which altitudes?

[Pal Meir]

According to the palm literature Lytocaryum weddellianum grows at altitudes between 50 and 800 m and Lytocaryum insigne from 1000 to 1800 m (Noblick 2017). But those limitations seem to be not correct. Below four habitat photos showing L insigne at c. 500 m and L weddellianum at c. 900 m (and 1200 m imo):

This palm is imo also L weddellianum, but I am not sure:

PS
Those four photos were once posted on Panoramio which was a very informative platform combined with Google Earth, but is to my deep regret no more existent :-(

Distribution
The species is endemic to Brazil, occurring in the Atlantic Forest, in the states of Espírito Santo and Rio de Janeiro (Leitman et al., 2012), at altitudes of 1000-1800 m (Lorenzi et al., 2010). However, Lima and Soares (2003) state that the species occurs from 700 m in the Biological Reserve of Duas Bocas, Espírito Santo.

Two examples growing in altitudes of 560 m and 600 m, far below of 1000-1800 m (Noblick 2017: 118):

Having checked all locations in Noblick 2017: 118 om Google Earth I came to following results for L insigne: 300 m (!) to 1800 m.

It is possible that some species grow at sea level and also high in the mountains, like Geonoma schottiana here do. So it doesn' t surprise me. It shows the palm is adaptable.
