In riower atul fruit this specits liardly differs from T. cannahina, Linn, f., of 

 which it may only he a local form. This is especially true of the form {Hildebrandt^ 

 1981), which Dr. Pax has described as subsp. r/laucescens, which can hardly, as 

 rrffards foliage, be separated from T. involucrafa, var. intermedia, Miill. Argf. 

 {T. tripartita, Beille, not of Schweinf.) and is only distinguishable by its strictly 

 erect habit.

 Stems erect from a woody base, 1 J-2 ft. high, rather sparingly virgately 

 branched, sparsely armed with white stinging hairs, otherwise glabrous. 

 Leaves distinctly petioled, ascending, membranous, deeply 3-partite, 

 lobes lanceolate or linear-lanceolate, acute, the central 4-7 in. long, 

 J-|in. wide, with undulate or coarsely toothed margin, lateral 1^2 in. 

 long, \ in. wide, with subentire or undulate margin, base narrow-cuneate, 

 with a few white bristles on the main nerves beneath, otherwise glabrous; 

 petiole \-\ in. long, sparingly white bristly ; stipules lanceolate, reflexed, 

 membranous with setose margins, 1 J lin. long. Racemes androgynous, 

 terminal on the stem and bmnches and below leaf-opposed, 2 in. long, 

 on naked peduncles 1-3 in. long, rather sparingly beset with short 

 spreading white bristles, with numerous rather lax male flowers above 

 and 1-3 basal female ; pedicels in both sexes glabrous, solitat y to and 

 shorter than their bracts ; bracts lanceolate, acuminate, males 1 J lin. long,
