ONCOCYCLUS 103 



According to my experience this is the most easily 

 grown of the Oncocycli. The form choschab, imported 

 by Mr C. G. van Tubergen, is perhaps the typical form, 

 which, among others, was described by Steven. 



Several hybrids have been raised. " Paravar," a cross 

 from /. variegata, by Sir Michael Foster, is figured in 

 the Gardeners^ Chronicle, June 22, 1 90 1, and on the next 

 page is figured the hybrid " Alkmene," raised with 

 /. Siverti by Messrs Dammann & Co. Sir Michael 

 Foster has also raised hybrids with /. sambucina, I. 

 Lorteti, L tberlca, I. lupina, and /. Meda. He has combined 

 paradoxa, Korolkoivi, and pallida.

 June 22, p. 397, fig. 152. " A very perky little Iris," 

 so distinct and good as to be worthy of commemorating 

 the late Rev. H. Ewbank. It was imported by Messrs 

 van Tubergen. The rhizome is of ordinary Oncocyclus 

 type. The leaves are glaucous, linear, 6 in. long, \ in. 

 wide. The stem is TO in. high ; spathe valves narrow 

 pointed, not inflated, reaching beyond the tube, quite 

 green till some time after flowering. The falls are 

 spreading, without tendency to recurve, lanceolate and 

 pointed, with thin beard of stout yellow hairs tipped 

 with brown ; the ground colour is creamy white, marked 

 by irregular veins of brown purple colour, thicker and 

 more jagged on the claw than on blade. The " signal " is 

 small but conspicuous, of purple black colour. The stan- 

 dards are erect, ovate, lanceolate, of creamy white ground 

 colour, veined with brown purple, a few yellow, brown- 

 tipped hairs forming an incipient beard along the median 

 line of claw. The style, deeply vaulted from side to 

 side, has an upper surface of almost uniform chocolate 

 brown, and an under surface lighter in colour, with 

 brown purple spots on a yellowish ground. The crests are 

 fairly large, quadrate, marked with thin, broken, brown- 

 purple lines. The ovary is longer than the tube, which
