OrcMd6es (Suite). 



Fig. 1. Listere cordiforme. Foe plante rare 

 et bien graciease, qui croit entre des touffes de 

 mousses dans la forfit de la region montagneuse 

 jusqu'a 1600 m, ainsi dans le Maderanertal, Uri, 

 Meerenalp au MQrtschenstock ; Ct. de St. Gall, 

 au-dessus d'Amden sur le Wallensee etc., mala 

 aussi dans le Jura. 



Fig. 2. Corallorhize. Une plante charac- 

 teristique de 1'humus, sans chlorophylle, vit 

 des substances organiques du sol. Le rhizome 

 ressemble a une coroUe et porte directement 

 les petites rhizoides, une racine manque. 



Humus au hois de haute futaie dans la 

 region des coniferes de 1000 a 1900 m. 



Fig. 3. Orchis globuleuse. L'inflorescence 

 eat ronde et ressemble a un petit globe. 



Prfis de la region montagneuse et alpine 

 1000 a 2400 m. 



Fig. 4. Coeloglosse vert. Les 6 feuilles 

 dorsales du perigon sont d'un rouge brunatre. 

 la levre verdatre. 



Prairies maigres, de la plaine jusqu'a 2400 m. 



Fig. 5. Epipogon sans feuilles. Le rhizome 

 subterrane est sans racine, Wen fragile et pale, 

 il porte de longs stolons, quo produisent de 

 nouvelles plantes. Souvent pendant des annees 

 la plante ne fleurit pas, ainsi qu'elle parait 6tre 

 disparue, pour reparaitre subiteraent en grand 

 nombre. Kile vit aussi de 1'humus, et manque 

 done de chloropbylle. La tige est transparent*, 

 la fleur est caracterisee par la levre tournee en 

 haut et par 1'eperon epais et courbe. La plante 

 d'un aspect bien et range et bizarre se trouve 

 dans la haute foret parmi on tapis de mousses 

 et sur le feuillage pourri, rare 600 a 1500 m.

 Orchids (continuation). 



Fig. 1. Heart-leaved Listera. A small deli- 

 cate plant sprouting out of the cushions of Moss 

 of the Alpine forests. Hare! From the plains 

 up to about 1600 m. (Weisstannenthal, Matt- 

 stock and Caplonerwald above Amden, below 

 the Meerenalp on the Murtschenstock, Made- 

 ranerthal etc. also in the Jura.) 



Fig. 2. Spurless Coral-root Without chloro- 

 phyll and without leaves, growing in mould 

 formed from the organic detritus of the soil. 

 The rhizome which is branched like coral creeps 

 in the mossy soil; the plant has no roots at 

 all, the slender root-hairs being attached im- 

 mediately to the underground stem. 



Mossy blocks of stone, old pine woods (more 

 rarely in beech-woods), in the mountain and 

 pine region, from 10001900 m. 



Fig. 3. Globe-headed Orchis. Easily known 

 by its compact globular sp'ke of flowers and 

 the filiform appendices of the petals being 

 broadened at their ends. 



Meadows and ,,Wildheuplfitze" *) of the pine 

 and Alpine region. 10002400 m. 



Fig. 4. Green hollow-tongued Orchis. Cha- 

 racterised by the peculiar brownish red colour 

 of the tips of the petals and sepals and the 

 greenish colour of the lip. 



Poor meadows ,,Wildheupiatze, from 1100 

 to 2400 m, but often descending lower down 

 (to 400 m). 



Fig. 5. Leafless Epipogon. The underground 

 rhizome is branched like the horns of a stag 

 as in No. 2; it is pale, very brittle and root- 

 less. It forms long creeping runners which 

 produce new stems. The plant often does not 

 flower for years together and seems to have 

 quite disappeared but suddenly comes to light 

 again. It grows like No. 2 (CoraUorhiza) in or- 

 ganic detritus in woods and therefore requires no 

 chlorophyll. The stem is semi-transparent, the 

 flowers have a fantastic appearance produced 

 by the lip being turned upwards and by the 

 thick bent spur. The plant makes a startling 

 impression when it peers out from the mysterious 

 darkness of the woods, pale and ghostlike. 



In old, closely grown beech and pine forests, 

 leafmould, among moss or on decaying wood, 

 rare e. g. Vittis, Gonzen, Werdenberg, Mollis, 

 Matt (Sernfthal), Altenoren, Rigi - Klosterli, 

 Weggis, Grafenort, Flinas, Champery, Vercorin 

 (Eifischthal), Binn. 6001600 m.
