the region below 2,000 feet. He notes a fine grove of silver-tn 

 and compares the thick growth of evergreen shrubs to the "mao- 

 chie of Corsica and Algiers," but notes that this formation at the 

 Cape is much richer in species than the corresponding formation 

 in the Mediterranean regions, and that there were more species 

 with showy flowers. Especially conspicuous were species of 

 Podalyria (Leguminosae) Polygala (milk-wort), sumacs, and many 

 others. 



White, pink and scarlet heaths were abundant and among the 

 rocks were stone-crops (Crassula, Cotyledon, Rochea) with fleshy 

 leaves and showy pink or scarlet flowers. 



The blue African lily (Agapanthus) is also a common plant of 

 this region, as well as many of the showy Iridaceae already men- 

 tioned. 



The fine Protect cynaroides belongs to Table Mountain also, and 

 one of the handsomest orchids, Disa grandiflora, with large scarlet 

 flowers. 



Among the common Compositae are species of Helichrysum, 

 a genus also abundant in Australia, and furnishing some of the 

 showiest of the garden "everlastings." Engler calls special 

 attention to two of the chaparral shrubs: viz., Cutwnia Co pens is 

 and Grubbia rosmarinifolia. The former is a monotypic speci' 

 belonging to the essentially southern family Cunnoniaceae. 

 Grubbia represents a family, Grubbiaceae, confined to the Cape 

 region. 



The Cape is not rich in ferns, as the long diy summer is not 

 favorable to most of them. Nevertheless there are some interesting 

 species in the sheltered gullies, or rock crevices. One of the most 

 notable is Todea barbara, a very handsome fern which also occurs 

 in Australasia. In some of the gulches of Table Mountain, a 

 small tree-fern, Hemitelia Capensis, occurs, and a single small 

 filmy-fern (Hymenophyllum) was noted by Engler. At Muizen- 

 berg, near Cape Town, the writer collected specimens of the inter- 

 esting Gleichenia polypodioides belonging to a family having no 

 representatives in Europe or the United States, but common in 

 the warm temperate regions of the southern hemisphere. 



Just as many plants native to the Cape have been introduc 

 into other countries, so one may see in Cape Town a great many 

 trees, shrubs, and herbaceous plants brought from abroad. One
