Lavrung and Horpa are classified by Lin 1993 as "northwestern dialects" of Rgyalrong, but otherwise the scholarly consensus deems the distance between them and Rgyalrong proper too great to be classified together, but still recognizes a special relationship, notably in verbal morphology.
Lavrung and Horpa are classified by Lin 1993 as "western dialect" of Rgyalrong, along with Eastern Rgyalrong and the "northwestern dialect" (Japhug, Tshobdun and Showu). Otherwise, the scholarly consensus deems the distance between them and Rgyalrong proper too great for them to be classified under a single branch, but still recognizes a special relationship, notably in verbal morphology.
