POGONIRIS 143 



96. I. sambucina, Linn. Sp. Plant. 55 ; Bot. Mag., t. 

 187 ; Reich, Ic. FL Germ., t. 335, fig. 762. The strong 

 scent of elder, on account of which the name is given, 

 is characteristic of this plant. Mr Baker regards this as 

 differing from the last by its less robust habit, narrower 

 perianth segments, and falls coloured and veined with 

 claret not lilac purple, and in the conspicuously emar- 

 ginate standards as well as in the more decided elder- 

 like scent. I have the wild plant, and its standards are 

 not, I think, noticeably emarginate. The flower may be 

 described as follows tube f in. long, limb 2f in. long ; 

 falls obovate-cuneate, if in. broad ; upper half of blade 

 plum-purple with faint indication of darker lines, below 

 this, lined with purple on whitish ground, the haft 

 veined with brownish-purple on yellowish-white ground ; 

 beard yellow, the hairs tipped with dark purple ; standards 

 broadly obovate, slightly broader than the falls, of sombre 

 purplish-yellow colour; style arms ij in. long, including 

 the crests ; crests ovate lanceolate, toothed on outer edge, 

 colour similar to standards. Is native of Central Europe 

 to the Caucasus and Armenia. Is flowering this year 

 (1903) at Cambridge in June, with squalens (rather earlier) 

 and lurida. 



97. I. germanica, Linn. ; Bot. Mag., t. 670 ; Red. 

 Lit., t. 309; Ic. Fl. Germ., t. 338, fig. 365. This is the 

 commonest of all Irises and is yet indispensable. It 

 adorns the cottager's garden all over the country. The 

 rhizome is stout, readily spreading. The leaves are 

 glaucous, I to 1 J ft. or nearly 2 ft. long, if in. broad ; the 

 stem is about 2 ft. long, valves oblong lanceolate, tinged 

 with purple-green in the lower half at flowering time ; 

 pedicels short. The perianth-tube is cylindrical, purplish, 

 not quite an inch long, limb 2 \ to 3 J in. long ; falls 

 broadly obovate-cuneate, dark purple, 3^ in. long, \\ 

 to 2 \ in. broad ; beard bright yellow or pale yellow \ 

 standards as broad or slightly broader than the falls,
