Peradenia, in the winter of 1865, plants from which flowered, 

 in moderate heat, at Kew, in September, 1866. It belongs 

 to a most puzzling group of this genus, in which the leaves 

 are sometimes opposite or whorled, but more often alternate, 

 and is most closely allied to, if not identical with, the L 

 flaccida of this work, Tab. 5276, differing chiefly in the 

 broader leaves. Thwaites, indeed, refers I. flaccida to the 

 Iinneean I. latifolia, but describes it as a decumbent plant, 

 which does not accord with the habit of the original specimen 

 in the Linnamn herbarium. Unfortunately the locality of 

 the Linna?an specimen is unknown ; it is marked as from 

 the Cape of Good Hope, obviously erroneously, and has the 

 spur bifid at the apex (an abnormal feature). Lastly, L flac- 

 cida, according to Thwaites, is a lowland plant, ascending to 

 an elevation of 3000 feet ; whereas the present is a mountain 

 species, occurring between 4000 and 7000 feet. It is also a 

 native of the ghauts of Western India. 



Descr. A shrub, two to four feet high, much branched, 

 quite glabrous. Stems terete, rather swollen at the joints. 

 Leaves usually alternate, sometimes, especially in peninsular 

 Indian specimens, opposite or whorled, petioled, very variable 

 in size and shape, two to four inches. long, ovate or ovate- 

 lanceolate, acuminate, sharply serrate, lower serratures seti- 

 gerous, as is the petiole. Flowers in solitary, one-flowered, 

 axillary peduncles, one to two inches long, flat, an inch to 

 an inch and three-quarters in diameter, pale purple. Lateral 

 sepals small, green, oblong-lanceolate. Lip concave, green, 

 with a long, slender spur. Upper petal deeply two-lobed, 

 with a green horned keel at the back. Wings spreading, 

 upper lobe largest, emarginate, all obtuse. — J. L). H.
