Tlnirsacnntlnis ^f'Jiombiirci'kla nii-'i is a tine 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 hahit and pendulou.s gr-ace of its long sprays 

 of slender, red, tulmlar flowers. Like many (dher acan- 

 thads, it becomes leggy and weedy in old ]dants, even 

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

 the second season. The culture of Thyrsacanthus is 

 easy. It is an ideal plant for a general collection, as it 

 requires no special treatment. Some Englisli writers 

 advise a stove temperature, but the undersigned has 

 grown it (or many years in a coolhouse. Ordinary pot- 

 ting soil such as suits geraniums will do for Thyrsa- 

 canthus. It flowers about April and remains in bloom a 

 long time. Cuttings may l>e made at any time in early 

 spring and will produce flowering plants 2-2k_. ft. high 

 the first season. After flowering, they should be cut 

 back severely. It is not desirahle to have more than om- 

 plant in a pot, nor should the young plants lie pimdied 

 the first season, as the umbrella form is prefer:dile to 

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

 lous habit ot Thyrsacanthus has suggested to some gar- 

 deners the use "of this plant for hanging li;iskets ami 

 brackets. Rcbekt Sh(M;e.

 m ill 1:11 . T. Si'iiiii'iisi.i is a tall Indian bamboo which h:is 

 been offered in southern California since the article 

 Bnmboo was written for this work. As the plant is not 

 included in Mitford's Bamboo Garden, its horticultural 

 status is uncertain. Franceschi writes that thi' plant is 

 rather tender at S;tnta Barbara. The genus belongs to 

 a snbtribe of bamboos of wdiich Dendrocalamus is the 

 type. This suhtribe is distinguished by having tj sta-
