A. Westlandi, Helmsley in Britten Journ. Bot. vol. xxiii. (1885), p. 286. 



Under his description of this plant, in the Journal of 

 Botany, Mr. Helmsley observed, " The foliage of this is so 

 like that of A. longifolia, that without flowers, one might 

 regard it as a variety ; but the flowers are nearly three 

 times as large, and appear to be very different in shape, 

 having a relatively shorter tube." A. longifolia is a Hong 

 Kong species, of which a figure is given at Tab. 6884 oi* 

 this work, taken from a plant that flowered at Kew the 

 year following Mr. Helmsley's description of A. Westlandi, 

 and an inspection of it fully justifies that botanist's re- 

 marks in all respects. It does not, however, solve what 

 appears to me the doubtful point, that is, whether West- 

 landi may not represent a large-flowered race of longifolia, 

 for the column, which Mr. Helmsley describes doubtfully 

 as six-lobed, is truly three-lobed, and accords in size, 

 number of anthers, their villous margins, conical summits, 

 and all other particulars with that ot A. longifolia, leaving 

 nothing but the size of the perianth whereby to distinguish 

 the two plants. Referring to the Herbarium, I find 

 numerous native specimens of A. longifolia, and all are 

 identical with the published figure cited above, and show 

 no trace of an intermediate character; I therefore retain 

 the two as representative species, of which the insular 

 {longifolia, of Hong Kong) is small-flowered, the continental 

 {Westlandi) large-flowered. A. Westlandi is a native of
