 Riverbank at Wang Chow; common (No. 72). 



39. STAUROGYNE SI AMENSIS C. B. Clarke, sp. nova; spicis sub- 

 globosis, in axillis (fere omnibus) quasi-sessilibus, foliis floralibus spathulato- 

 orbiculatis intermixtis; spica terminali (imo in fruclu) ovoidea; corolla vix 

 1 cm. longa; S. glaucaeO. Kuntze Var. spathulata? arcteaffinis. Annua, 10-18 cm. 

 alta. Folia-Iamina usque ad 7 cm. longa spathulato-elliptica, obtusa; petiolus 

 5-12 mm. longus. Capita in pedunculis 0-2 mm. longis, admodum pilosa, 10-14 

 mm. in diam.; folia floralia 8-9 mm. longa. Sepala linearia vix 5 mm. longa. 

 Corollae tubus reclus. Capsula 5 mm. longa. 



This uew species comes next to Staurogyne glauca, 0. Kuntze var. spalhulata, 

 i. e. Ebermaiera spathulata, Hassk. It differs in the spathulate-orbicular floral 

 leaves ; and greatly in the very axillary inflorescence. In Hasskarl'sE. spathulata 

 the terminal spike is linear elongate in fruit (C. B. Clarke). 



Near Tapotsah ; open places in woods (No. 9, 10, 11, 25). 



40. Hygrophila phlomoides Nees; Hook, f., 1. c. 408.

41. NOMAPHILA SI AMENSIS C. B. Clarke, sp. nova; herbacea, 

 erecta, ramosa, foliis tenuibus: inflorescentiis oblongis (nee globosis), Iaxis, a 

 foliis floralibus pluribus oblongis ornatis ; ceteroquin ut N. strieta Nees. Caulis 

 3-6 dm. altus, ramis pluries divisis. — Differt a N. strieta ob cymulos laxos a 

 bracteis interspersos. 



This new species is closely allied to Nomaphila strieta Nees (and other Noma- 

 philos). It differs in the herbaeeous much branched stem, the oblong (not globose) 

 inflorescences, which have many scattered oblong floral leaves; and do not 

 match the recurved denser inflorescences of N. strieta, Nees. (C. B. Clarke).
