Some may contend that H. Desetanrjsii is a hybrid form or 

 //. qaadrangulnm crossed with H. perforatum (ff. tetrapterum is 

 even less likely), but if that were the case, some of the more 

 minute characters of perforatum would be present, such as the 

 peculiarly-shaped pellucid dots, long style, absence of membranous 

 margin to leaf, etc. 



It appears likely that the extreme form of H. quadrangulum 

 with very broad, obtuse, entire sepals is far from common in 

 Britain, our usual plant having these longer and narrower and 

 the lip often eroded or denticulate. Dr. Schinz has described 

 a variety erosum, and this, very likely, is our more frequent form. 

 Babiugton's var. maculatum (now var. Bahinytonii) is probably the 

 same. 



As regards the name " quadrangulum, L.," this has been used, 

 both on the Continent and in Britain, by various wi-iters to 

 denote either the large-flowered non-dotted-Ieaved plant or the 

 smaller-flowered dotted-leaved species in a most confusing manner. 

 An examination of the Linnean Herbarium shows that there is 

 some reason for this. Two sheets are pinned together, both 

 labelled " 13," which refers to H. quadrangulum in ' Species 

 Plantarum,' ed. 1. One of the specimens is H. tetrapterura, and 

 upon this sheet Smith has written " quadrangulum origiual sp." 

 The other example is labelled by Linnaeus " quadrangulare " 

 (altered by Smith to '■^ quadrangidum," who aho added "•duhium'?"), 

 and it is the plant with large flowers, non-dotted leaves, and short 

 obtuse sepals. 



Mr. Gr. C. Druce and Dr. Stapf commented on the exhibition, 

 and Mr. Salmon replied.
