Scaphoid Tubercle

Brief description Branching planar, pinnate, and plumose. Short and very narrow lateral branches arise from the main stem. The lateral branches do not branch further. Sclerites range in length from 0.05 to 0.16 mm, and are straight or slightly curved spindles with three to six transverse whorls of tubercles. Some scaphoids are distinct and have smooth tubercles on the convex side, while others are less distinct and have ornamented tubercles on both the convex and concave sides. The sclerites are yellow or red. ... 

From the palmar retinaculum, the tubercle of the scaphoid and that of the trapezium.
