2. T. fasciculata, Beille in Bull. Soc. Bot. France, lv. Mém. viii., 
83. Stems very many, subtriquetrous, slender, wiry, tufted from a 
cylindric woody horizontal rootstock, 4-5 lin. thick, erect, sparingly 
branched, the axillary branches all leafy ascending and virgate, densely 
clothed with spreading or subreflexed tawny setose hairs. Leaves dis- 
tinctly petioled, narrowly ovate-lanceolate, acute or acuminate, base 
slightly subhastate-auriculate or shallow wide-cordate, margin finely 
serrate throughout, 14—2in. long, }-4in. wide across the base, }-4in. wide 
at the middle, rather sparingly tawny-pubescent, more densely so along 
the nerves on both surfaces; petiole }-} in. long, densely tawny-pubes- 
cent ; stipules lanceolate, erect, 1 lin. long, sparingly setose. Racemes 
androgynous or at times I-sexual, terminal on the stem but not on 
the leafy branches and leaf-opposed below, slender, very lax-flowered, 
6-10 in. long; bracts from the middle downwards }-1} in. apart, 
gradually more remote, with a short naked densely pubescent basal 
peduncle $ in. long; flowers all male or with a solitary basal female ; 
pedicels in both sexes pilose, shorter than their bracts ; uppermost male
