In these thiekets are several species of temperate zone affinities, 

 including Berheris aristala, Ruhus lasiocarpus, R. moluccanus, 

 Lysimachia ramosa, Valeriana Moonii, Campanula ful^ens, San- 

 icula europaea, Gaullheria fraf^rantissima, Ruhia cordifolia, and 

 Cynoglossum micranthum. Ulex europacus is naturalized freely 

 in the patanas immediately about the town of Nuwara F^liya, 

 and seems to flourish. Verbascum Thapsus is also a common 

 roadside weed, but appears less hairy than in America. 



The most noteworthy roadside plant of the region is a lobelia, 

 L. nicotianaefolia. It has the general habit of the mullein, and 

 grows in the same habitat, but its suffrutescent stems reach a 

 height of twelve feet. 



Six miles from Nuwara Eliya along a beautiful macadamized 

 road lies the mountain garden of Hakgala. It is located at an 

 altitude of about 5,000 feet, at the foot of the precipitous Hakgala 

 Peak. The garden grounds are very attractive, and present a 

 very interesting display of conifers and tree ferns.

PARTHENIUM LLOYDII, A NEW MEXICAN GUAYULE 



By Harley Harris Bartlett 



In the summer of 1909 Prof. F. E. Lloyd referred to the writer 

 for study and description a Parthenium which he believed should 

 be segregated from Parthenium argentatum, the rubber-plant of 

 Chihuahua and neighboring states. Since that time Prof. Lloyd 

 has pointed out and illustrated the distinctive characters of the 

 two plants,* so that it is only necessary to present an abstract 

 of his account and a formal diagnosis of the new species. 



In Parthenium argentatum the monopodial growth of the seed- 

 ling is terminated by the development of the first inflorescence. 

 Extension of the stem system takes place at the base of the well- 

 dififerentiated peduncle, by the growth at that point of two or 

 three branches, whose growth is in turn terminated by inflores- 

 cences. As a result of this sharp delimitation of leafy stem and
