the posts take root after the manner of willows, but because the fence 

 consists of rows of grooving plants. The species universally employed 

 for this purpose is one of the pineapple family known as the pinguiella 

 {Bromelia Plnguin). It has pineapple-like leaves with very sharp 

 recurved prickles, and as it suckers freely from the root it very promptly 

 forms a hedge impervious even to the itinerant pig. The red spikes of 

 flowers are succeeded by a yellow berry-like fruit of a not unpleasant 

 flavor. 



The so-called calla lily, now so widely known in cultivation, is a 

 native of the Cape of Good Hope. Following is a short extract from an 

 article in Gardening on the "Native Flowers of South Africa," in which 

 the home of the calla is described : " In Cape Colony, for man 3^ miles 

 between Paarl and Cape Town, the line is bordered with so-called ' pig- 

 lilies.' These are none other than our carefully tended and garden- 

 produced arums or callas. But in South Africa they grow wild and in 

 luxuriant profusion. Near Ceres there are great fields full of these 

 snowy white blooms with their orange yellow spadixes." 



A NEW station for the interesting plant known as rose-root, or 

 Sedwn roseum (the Sedum Rliodiola of Gray's Manual) has recently been 

 recorded by Arthur N. Leeds, of the Philadelphia Botanical Club. Mr. 

 Leeds discovered it in some abundance last summer growing along the 

 upper Delaware River near Port Jervis. Only two Eastern stations are 

 known for the plant south of this ; one of these being in Bucks County, 

 Pennsylvania, and the other on Roan Mountain, North Carolina.

The largest and most valuable collection of orchids upon the Pacific 

 coast, and one of the best in the United States, is that of John C. Sieg- 

 fried, Alameda, Cal. For years this collection has remained little 

 known, even to the people of Alameda, but hereafter it is to be open to 

 the inspection of the public. Here are gathered 2760 plants, including 

 some 170 varieties, among them many rare things which could scarcely 

 be duplicated. Mr. Siegfried places the value of the collection at not 

 far from $70,000. F. O. Vincent is the gardener in charge, having been 

 on the place six years. Prior to that he spent six years in charge of the 

 conservatories at the Golden Gate Park, San Francisco. — Californian
