While a standard walnut grows natively with only two ribs, an extraordinarily rare genetic anomaly yields the \u003ci data-path-to-node=\"10\" data-index-in-node=\"237\"\u003eSan Leng Ben\u003c\/i\u003e—the Three-Ribbed mutation. This structural miracle splits the shell into three balanced chambers, creating a triangular symmetry that resembles the iconic Mercedes-Benz three-pointed star emblem when viewed from the base. Combined with Nanjiangshi's signature flat bottom and prominent straight seams, this variety is highly valued for its physical density and distinct geometric handling.\u003c\/p\u003e\n\u003chr data-path-to-node=\"11\"\u003e\n\u003ch3 data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003e[Product Characteristics of NJS-1007]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"13,0,0\"\u003e\n\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eThe Triangular Ergonomic Geometry:\u003c\/b\u003e Measuring 40.0mm in width paired with a 38.0mm belly depth.
