F. B. White, as a hybrid of reticulata and lapponum. There are many 

 minor alterations and corrections of previous identifications. 



2317 (2). Helleborine viridiflora Wheldon & Travis in 

 Journ. Bot. 343, 1913. Among Salix repens, from Hall Road, Lanes. 

 S., to South Shore, Lanes. W. The description given of it by the 

 authors is " Plant less robust than H. latifolia or H. violacea 

 [purpurata] with, a more slender and wiry stem. Rhizome, slender, 

 far-creeping. Steins, solitary, 2 — 5 dcm. high, almost glabrous below, 

 with short pubescence above : base deeply tinged with violet purple. 

 Lower sheaths, several, amplexicaul, often rather loose, the uppermost 

 slightly funnel-shaped. Leaves, of a fresh yellowish-green almost 

 all completely embracing the stem, arcuate, and with a tendency to 

 fold conduplicately : lower and intermediate ones elliptic-lanceolate, 

 the upper linear-lanceolate, acuminate, usually few and distant. 

 Flowers, yellowish green in colour, without any trace of purple or 

 rose, in a lax few-flowered raceme, shortly pedicellate, the lower ones 

 exceeded by the bracts : less inclined and opening earlier than in H. 

 latifolia. Label, whitish-green, triangular-cordate, acuminate, entire 

 or slightly irregular at margin, straight, or but slightly recurved at 

 apex : with two low slightly wrinkled basal bosses or hunches, 

 separated by a median space. Hypochile, very ventricose, with white, 

 strongly reflexed anterior margins. Germen, large in proportion to 

 the size of the flower, glabrous, or with a few scattered, soon deciduous 

 hairs. Flowering period, from mid- June to end of July." 



Rouy (Fl. Fr. xiii., 204) treats it as a race of E. latifolia, and 

 says it is synonymous with E. Helleborine, var. variants Reichb. Ic. 

 Fl. Germ. t. 487, f. 1 et t. 488, f. 8, not of Crantz. He gives the follow- 

 ing description, which shows certain points of difference from our 

 English plant, and says it is often confused with green-flowered 

 forms of E. atropurpurea (under which he puts E. media), but he 

 gives no dunal locality. " Gaines inf. de 1' E. latifolia : plante plus 

 grele (2 — 5 dec), a tige moins robuste: feuilles relativement etroites, les 

 inf. et les med. elliptiques-lanceolees, acuminees, moins larges que 

 dans le type, a bords souvent ondules, les sup. lineaires-lanceolees : 

 fleurs d'un vert-jaunatre, moins nombreuses, non inclinees, en epi plus 

 lache : epichile blanc a la marge, a apophyses peu distinctes ou nulles." 



As to the grade in which this plant should be put, opinions will 

 vary, but botanists will probably admit that few plants respond more
