32. Sphagnum portoricense Hampe    异叶泥炭藓 yi-ye ni-tan xian
Linnaea 25: 359. 1852. Type. Puerto Rico.
Plants grayish green, or yellow above, brownish orange below, in beautiful shiny tufts. Stem cortex in 3–4 layers, hyaline cells with delicate fibrils, each cell with 1–3 large pores; central cylinder brownish. Stem leaves 
1.0–1.2 mm × 1.0–1.1 mm, broadly lingulate with a broad apex; margins borders hyaline, differentiated, sometimes with fringed fibrils across the apex; hyaline cells mostly divided, often without fibrils, or with fibrils only in the upper cells. Branches in fascicles of 4–5, with 2–3 spreading. Branch leaves 2.5–3.5 mm × 2.0–2.5 mm, broadly ovate, strongly concave, narrowed at base, margins involute and hyaline, cucullate-concave and sometimes fringed and dorsally roughened at the apex; hyaline cells with large, rounded pores on the ventral surface, with numerous, half-circular pores at the opposite ends along commissural rows and membrane pleats in the upper cells on the dorsal surface; green cells in cross section rather large, nearly equilateral-triangular, exposed on the ventral surface. Dioicous. Sporophytes not seen.
