Laurelin and Telperion

[Galin]

It's noted that Telperion had white blossoms like a cherry, and that Laurelin had leaves like a beech -- though generally it was also noted to have been 'founded' on the laburnum:

On the carbon copy of LQ 2, which otherwise received no emendations, my father added the following note to the word spilth in the last sentence: meant to indicate that Laurelin is 'founded' on the laburnum. 4 'jocund spilth of yellow fire' Francis Thompson — who no doubt got the word from Timon of Athens (his vocabulary was largely derived from Elizabethan English)

Morgoth's Ring

In a note published in The Attack on Weathertop (Return of the Shadow)...

'For as it is told the Blessed Realms of the west were illuminated by the Two Trees, Galathilion the Silver Cherry, and Galagloriel that is Golden Rain.'

If that helps any (despite the Elvish names at this point)!

Looking quickly on the web (!) sometimes laburnum = Golden Rain but I'm no expert here; I see Golden Chain on the web as well.
