Planta 30-45 cm. alta, vix robusta, erecta, simplex, 

 subtortuoso-flexuosa, subaraneoso-puberula vel glabrescens, 

 e tubere circ. 5 cm. longo ovoideo vel ellipsoideo orta ; apice 

 tuberis primarii abeunt stolones subterranei, sex vel plures, 

 30-40 cm. longi, tuberibus terminati, foliis reductis squami- 

 formibus remotis praediti. Folia radicalia mox delapsa, 

 mihi ignota ; folia caulina plura petiolo 3-6 cm. longo, 

 supra alte sulcato, basi vaginante, apice anguste alato 

 praedita, latiora quam longiora, ovato-triangularia, rarius 

 5-gona, plerumque 6-8 cm. longa, 8-12 cm. lata, basi perlate 

 cuneata, saepius truncata, apice acuta vel subacuta, margine 

 nunc aeque nunc irregulariterindurato-dentata,nonnunquam 

 sinuato-lobatula, supra atroviridia puberula, infra pallidiora 

 sparse araneoso-tomentella vel glabrescentia nervis pal- 

 matim abeuntibus eminentibus. Inflorescentia terminalis 

 8-10 cm. longa, basi foliata, folia suprema paulo superans, 

 anguste paniculata, racemis plerumque siinplicibus com- 

 posita, araneoso-puberula ; bracteae numerosae lineares vel 

 lanceolatae, 2-4 mm. longae, sparse araneoso-tomentellae ; 

 pedicelli bracteis breviores ; capitulum floribus apertis 

 10-12 mm. longum; involucri phylla 5, circ. 8 mm. longa, 

 viridia, glabra, nitentia, fere ad apicem cohaerentia, tubum 

 angustum dentibus quinque brevibus lanceolatis praeditum 

 formantia ; flores paulo f ragrantes (tunsi odorem Senecionis 

 Jacobaeae suggerunt), in capitulo quoque plerumque 4, 

 quorum unus rarius duo ligulati ; flores ligulati 1*4 cm. 

 longi, anguste oblanceolati, apice 2-3 denticulati, flavi ;

Central China. — Cultivated in the Royal Botanic 

 Garden, Edinburgh, from seeds (Wilson, No. 1066) received 

 from the Arnold Arboretum in 1909. Plants flowered in 

 July-August 1912, and the above description is based on 

 them. The long tuber-bearing stolons are very striking, 

 and distinguish the plant from any Chinese species known 

 to me. The single ligulate flower (rarely two) in each 

 capitulum is also noteworthy.
