 — A common plant in uhl iiaidens, iTi/.-d as an ever-

 for seasoning, as those of T. vulgaris are. The nodes 

 are short, making it a very leafy plant. Variable.

 herbs or shrubs with opposite, often large leaves and

 lipped; stamens 2; staminodia 2, small, at the base of 

 the filaments: capsule oblong; seeds i or fewer by 

 abortion.

Tliyrsacantlins Schomburgkianus is a fine old green- 

 house favorite which has of recent years fallen into un- 

 deserved neglect. It deserves a place in every good 

 general collection. It is chiefly admired for its um- 

 brella-like habit and pendulous grace of its long sprays 

 of slender, red, tubular flowers. Like many other acan- 

 thads, it becomes leggy and weedy in old plants, even 

 if cut back severely. Hence, plants are rarely kept after 

 the second season. The culture of Thyrsacanthus is 

 easy. It is an ideal plant fur a g.-neral collection, as it 

 requires no special tr.atiii.iit. S.im. i:iii;lish writers

 back severely. It is not desirable tu have mure than one 

 plant in a pot, nor should the young plants be pinched 

 the first season, as the umbrella form is preferable to 

 that of a compact, much-branched bush. The pendu- 

 lous habit of Thyrsacanthus has suggested to some gar- 

 deners the use of this plant for hanging baskets and 



brackets.
