Calibanus caespitosa Rose. By C. Sprenger (Bull. B. Soc. Tosc. 

 Ort. 4, 1907, p. 104). — Dr. C. A. Purpus discovered this quite new and 

 unpublished genus last year on the high and arid mountains of Northern 

 Mexico. Seeds, along with a shoot collected on the rocks of that country, 

 were sent to the writer, who now has plants of it growing freely at 

 Naples. The new genus stands midway between Dasylirion Zucc. and 

 Nolina Mich., with which is reunited Beaucarnea of Lemaire ; Nolina 

 is a synonym of Boulinia of Brongniart. 



Nolina bears polygamo-dioecious, and Dasylirion simply dioecious, 

 flowers. The flowers of Calibanus have not yet been examined. 



C. caespitosa grows on rocks exposed to the burning sun. It grows 

 at a height where snow regularly rests, and where the thermometer falls 

 below 10° R. It forms very dense colonies and often covers the entire 

 mountain with its rigid leaves. The greater part of the stem is above 

 ground ; it is very broad and hard, and grey like the rocks on which it 

 grows ; it is woody, dense in texture, and bears numerous tufts of leaves. 

 The stem bears thirty or more tufts of leaves, which are channelled, 

 rough, acute, veined, and glaucous, with a purplish-pink base. The 

 smallest plants have the aspect of, and resemblance to, some of the 

 Asphodclus of Asia Minor. The plant is quite hardy. The long peduncle 

 rises to a height of seven or eight feet, and is simple ; it is only slightly 

 branched at the top and bears myriads of ivory-coloured flowers. It is 

 visited by thousands of insects, especially bees. Its culture is of the 

 simplest, and its hardiness in Naples is a proved fact. — W. C. W. 



Calliandra portoricensis, var. major. By T. A. Sprague (Bot. 

 Mag. tab. 8129). — Nat. ord. Leguminosae ; tribe Mimoseac; Mexico and 

 Central America. Small tree with bipinnate leaves, two to seven pairs of 

 pinnae ; heads 2 inches diameter ; flowers white ; stamens 1 inch long.

 and 1 woodcut). — The plate represents extremely fine forms, white and 

 blue, of this species ; flowers very large, resembling somewhat Clematis 

 Jackmannii, the bell form being flattened and deeply cut.— C. T. D.
