76 ORCHID HYBRIDS. 



The nomenclature of this genus, if taken to Cypripe- 

 dium, would interfere in a few cases, viz.: giganteum, 

 Venus and robustum (robustius and robusticus, lingua 

 hortulanorum!). 



Regarding the varieties of Spd. longifolium, I have 

 preferred to follow the division of Rolfe (Gard. Chron. 

 Dec. 20, '90.) in Hincksianura, the Isthmus of Darien 

 form, Roezlii, from New Granada, and Hartwegii, the 

 Ecuador variety. 



Spd. longifolium is so variable a species that it can- 

 not be wondered at that all those crosses in which it took 

 part display a wonderfully great relationship; so much 

 so, in fact, that sooner or later some rearrangement will 

 have to be made defining those seedlings which display 

 a character rendering their certificate of birth liable to 

 forfeiture. I will mention those cases which came under 

 my notice. Spd. Albanense (Schlimii X Sedenii x) 

 Veitch's Manual, page 105, states " differs in no essential 

 character from the original Sedenii. " It is doubtful 

 whether Sedenii took any part in this cross, but if it 

 did not, I would not have referred it to that cross. 

 Further, Spd. porphyreum (longifolium ? X Schlimii), 

 Mr. Drewett 0. Drewett writes in his letter of March 3, 

 '93: " The seedlings varied greatly. I have as good a 

 variety of Sedenii candidulum as there is from this same 

 batch. The above is a very dark, if properly grown." 

 Again: (cardinale X longifolium) could "almost pass as 

 a light form of Sedenii." 0. R., Oct., '93. -Further, Mr. 

 W.Vanner, Camden Wood, Chislehurst, in 0. R., June, 

 '93, Spd. pulchellum (grande x ? X Sedenii candidulum 

 x). He states " they are remarkably like Spd. leucorr- 

 hodum x, notwithstanding the different parentage. The 

 influence of caudatuin is almost lost. Of the six plants 

 raised, none were quite alike." Remembering that
