Description

Stems clustered, non-climbing, short and subterranean or free standing, to 5 m, to 5 cm in diam. Leaf sheaths greenish brown with brown hairs, with densely arranged, black, needle-like spines to 2 cm; ocreas to 40 cm, spiny, fibrous and soon disintegrating; knees absent; flagella absent; rachis to 1.5 m with 28-49 lanceolate pinnae per side, these strongly clustered and spreading in different planes; middle pinnae 30-37 cm, 1.5-2 cm wide at mid-point, adaxial veins and margins bristly; cirri absent. Inflorescences to 1 m, erect, not flagellate; inflorescence bracts split open and tattering. Fruits reddish brown, ovoid or ellipsoid, to 1.5 × 1 cm. Editing by edric.

The sole specimen of C. scutellaris is a fragment of infructescence. There is no doubt that it matches the extensive material of C. thysanolepis at K. Beccari (1913) overlooked the similarity between these two taxa when he named C. scutellaris, comparing it only with C. scipionum. The strongly grouped, plumose leaflets are reminiscent of C. viminalis but the erect habit and short inflorescences with strongly lacerate bracts and broadly cupular involucrophores are very different. The status of var. polylepis C. F. Wei from Guangdong was not reassessed in the present study. (J.

Culture

Comments and Curiosities

There are two sub-species:

1.) Calamus thysanolepis var. polylepis; China Southeast.

2.) Calamus thysanolepis var. thysanolepis; China Southeast.

Uses: Fruits sold in Vietnam, presumably as food.

Conservation: Unknown, but suitable areas of lowland forest are scarce and declining in the one area of Indochina where is has been recorded.
