Naturalisation in Extra-Tropical Countries. 577 



"boiled, afford a nutritive and palatable food [M. Holtze]. Each pod 

 lias generally only one seed, somewhat larger than a pea [Dr. 

 Henkel]. 



Waitzia corymbosa, Wendland. 



Deserts of Australia. Quite ornamental. Sheep are particularly 

 fond of this herb and soon get fat on it [Mrs. M. Heal]. It is the 

 choice of horses, cattle and sheep when in flower [W. Webb], 



Wallichia caryotoides, Roxburgh. (Harina caryotoides, Hamilton.) 



India, up to 4,000 feet elevation [Kurz] . A dwarf tufted palm, 

 eligible for scenic group-planting. 



densiflora, Martius. ( W. oblongifolia, Griffith.) 

 Himalaya as far as 27 north. There one of the hardiest of all 

 palms. It is not a tall one, yet a graceful and useful object for 

 cultural industries. 



Washingtonia filifera, H. Wendland. (Pritchardiajilifera, Linden.) 



From South-California to Arizona and Colorado. One of the 

 most northern and therefore most hardy of American palms. This 

 species attains a height of about 50 feet. Of heavy massiveness like 

 most of the Sabals [Dr. Franceschi]. In gardens it passes often 

 under the name Brahea filamentosa. Thrives well near Melbourne 

 [C. French]. W. robusta (H. Wendland) occurs near the Sacramento- 

 River, and will endure long-continued drought as well as a few 

 degrees of frost [Prof. Naudin]. This is one of the most beautiful 

 among hardy Palms. 



Wettinia augusta, Poeppig. 



Peru, on mountains several thousand feet high. This palm 

 is therefore likely to endure mild, temperate climes. 



Wettinia Maynensis, Spruce. 



Cordilleras of Peru. Like the foregoing, it attains a height of 

 about 40 feet, and advances to elevations of 3,000 to 4,000 feet. 



Before finally parting from the American palms, it may be appro- 

 priate to allude briefly to some of the hardier kinds, including 

 besides some plants of closely allied orders. From Dr. Spruce's 

 important essay on the Palms of the Amazon-River may be learned 

 that, besides other species as yet imperfectly known from the sources 

 of this great river, the following kinds are comparatively hardy, and 

 hence might find places for cultivation or even naturalisation within 

 the limits of extra-tropical countries : Geonoma undata (Klotzsch), 

 Iriartea deltoidea (Ruiz and Pavon), Iriartea ventricosa (Martius), 

 which latter rises in its magnificence to fully 100 feet ; Iriartea 

 exorrhiza (Martius) ; this, with the two other Iriarteas, ascends the 

 Andes to 5,000 feet. Oenocarpus multicaulis (Spruce) ascends to 

 4,000 feet ; from six to ten stems are developed from the same root,
