bug with ls

[Jason Temple]

Greetings,
   I was trying to recursively list all the directories, *only the 
directories* on a linux system (debian, 8.10) and ran into a bug. 

ls -d /*    ---- lists all directories in /  (one level deep, expected)
ls -dR /*  ---- lists all directories in /  (one level deep, no 
recursive directory traversal)

I can use

find / type d  ----- which gives me the desired results, but I feel that 
ls -dR, from its man page should work in this capacity.

thanks,

jas
