29. SiSYRiNcmuM Linn. 



Perianth with scarcely any tube above ovary ; segments oblong, 

 snbequal, spreading from above the base. Stamens inserted at tlie 

 base of the perianth ; filaments more or less connate ; anthers 

 erect or versatile. Ovary turbinate or globose, 3-celled ; ovules 

 many, superposed ; style short, subulate ; branches subulate, stig- 

 matose at the apex. Capsule subglobose or turbinate, loculicidally 

 3-valved. Seeds many, minute. — IlJdznme none or very short. 

 Leaves linear or terete. Peduncle flattened or terete, leafless or 

 leaty. Flowers usually several in a cluster, usually blue or yellow. 

 Clusters solitary or fascicled, rarely spicate or panicled. Capsule ex- 

 serted from the spathe. I have classified the species according to 

 stem and inflorescence. Herbert's arrangement, founded on stamen 

 characters, will be found in Bot. Reg. 1843, Misc. p. 84, and Mr. 

 Bentham has followed this, with modifications, in ' Genera 

 Plantar um.'

Hab. Chili and Argentine republic. Differs from the dwarf one-headed 

 forms of jnnceiDii by its filaments free to the base. S. Ntiiio Colla loc. cit. t. 

 54, is doubtful. The stem is said to be ancipitous and the dower violet with a 

 yellow throat.
