Looks to me like "Ogalava" is an error. The rosewood being referred to by GfS may be Palisander de Rio Grande, which comes under several names...

"The pre-eminent rosewood appreciated in the western world is D. nigra known as Rio, Bahia, Brazilian Rosewood, Palisander de Rio Grande, or Jacarandá"

The only thing that "Ogalava" sounds much like to me is "Oglala"...Crazy Horse's particular section of the Lakota (Souix) Indian nation.
