Looking through the August 1979 issue of Byte magazine, it discusses a dialect of Lisp in which arithmetic operations are denoted by words like PLUS and TIMES.
Later dialects like Common Lisp and Scheme use the symbols common to other languages like + and *.

@Wilson It doesn't seem to say what the dialect is specifically called, or if it does, I missed it. The Byte issue can be downloaded in PDF if you want to take a look yourself.

Lisp is not a single language, but a whole ecosystem of different languages. Moreover, there's no standard covering all Lisps, like with C or Fortran, so for this reason, + and plus are equally "valid".
When Lisp 1 (March 1960) was written, the primitive operations defined were car, cdr, cons, and, or, cond, etc. The arithmetic operations were not primitives at that time, so the programmers chose their own names.
At least Lisp 1.5 (early 60s) had both.
But this Lisp from 1970 had PLUS and MINUS but no + nor -.
If you consider Scheme (1975) to be a Lisp, then it is a specimen having both + and &+ (the latter is an optimisation for two arguments only).
And Common Lisp (1984) has + but not plus as you have noted.
So I posit that we gradually settled on +-style symbols starting in the 70s, and the situation was a state of flux before then, for the reason that arithmetic operations were not even primitive operations to begin with.
