 ORNAMENTAL LADIES'-TRESSES 



Last year (Jour. N. Y. Bot. Gard. 34: 106-108), I published a 

 note on "Our Largest Ladies'-Tresses," Ibidium odoratum. The 

 subject of the note was a young plant brought to the Garden from 

 New Orleans, La. It flowered last fall and made three "suckers" 

 which were transferred to a pan. In the meantime Mr. J. B. Wal- 

 lace, of New Orleans, sent twelve young plants to the Garden. 

 These were set out, six each in two large pans. Eleven of the new 

 plants grew and flowered along with the three descendants of the 

 single plant that flowered in the fall of 1932. The plants began to 

 open their flowers the first week in September and continued to 

 flower until the first week in November (Figure i). 



In addition to the long flowering-season this autumn, two other 

 interesting features were evident. I. — Seven of the flowering- 

 spikes had a clockwise twist, while seven others had a counter 

 clockwise twist. II. — The fourteen separate plants have produced 

 forty-two "suckers." This indicates forty-two flower-spikes for 

 next fall's growth, or three new plants apiece for each plant now 

 flowering, just as the single plant last fall made three new plants 

 for this year's growth. For a plant accustomed to the normal soil 

 and fresh air of a southern swamp this plant shows remarkable 

 vigor when grown under glass in the North. Several of the flower- 

 stalks now measure more than two feet in height. One of the 

 flower-spikes is nine inches long as against the one six inches long 

 referred to in the note mentioned at the beginning of this note.

CONFERENCE NOTES FOR DECEMBER 



A conference of the Scientific Staff and Registered Students of 

 the Garden was held on the afternoon of December 13. 



Dr. Marshall A. Howe discussed "Riccia in the Galapagos 

 Islands," with reference to a considerable number of specimens of 

 this genus collected on these islands in 1932 by Mr. John Thomas 

 Howell, botanist of the Templeton Crocker Expedition of the Cali- 

 fornia Academy of Sciences. Although short lists of the Hepaticae
