Sylvae in jugis montium Turkestaniae sinensi atque 

 Mongoliae confinibus omnino desunt, luco uno alterove 

 parvulo montibus Nan-shan orientalibus excepto. 



In montibus Keria etiam frutices pauci qui praesto 

 sunt in ipsissimo tantum faucium fundo obvii fiunt: 

 Tamarix Pallasii, Myricaria Germanica, Caragana pyg- 

 maea, Hedysarum, Nitraria, Lycium turcomanicum. 



Altyn-tag declivitate septentrionali descendentes, 

 inter 9et 7000 p. s. m. invenimus Tamaricem laxam, Po- 

 pulum diversifoliam, Ephedram, Halostachyn orgyalem, 

 Zygophyllum, Reaumuriam, Kalidium, Kareliniam, 

 Phragmitem, Lasiagrostidem et nonnullas jam supra 

 enumeratas, ad radices montium in conspectum venit 

 Alhagi camelorum. 



In vallibus desertis inter juga Nanshanica immer- 

 sis ?3o"ra rara et aspectu grisea e Salsola abrotanoide, 

 Sympegmate Regeli, Astragalo monophyllo, Stellera 

 Chamaejasme, Potentilla fruticosa, Festuca, locis me- 

 lius irrigatis ex Hedysaro multijugo, Tamarice elongata, 

 Comaro Salessowii, Caryopteride mongolica, Hippophae, 

 Calimeri alyssoide, Salice, Mulgedio tatarico, Rheo 

 spiciformi, Gentiana barbata, Adenophora, Potentillis 

 aliisque composita erat. 



Prata alpina montium Keria parvula et speciebus 

 paucis frequentata: graminibus parcis, Artemisia par- 

 vula, Astragalis, Alliis, Iris, Statice, Saxifraga, Andro- 

 sace et aliis in Tibetia boreali vulgatioribus. Paulo me- 

 lior est aspectus pratorum alpinorum Nan-shani, zona 

 inter 1 1 et 13 mill. ped. sitorum, sed etiam hic minime 

 sunt dilatata saepeque interrumpuntur tum spatiis 

 fragminibus rupium obtectis, tum praeruptis saxosis. 

 Hic crescunt circiter 11 — 12 Oxytropes et Astragali, 

 inter eas Ox. tragacanthoides, Sterigma sulfureum, 

 Crepis Pallasii, Allium Szovitsianum, Potentilla multi- 

 fida; et adhuc altius, latere boreali usque ad 13,700 

 p. s. m., latere austraii ad 15000 p. s. m. inveniun- 

 tur dispersae: Saussurea sorocephala, Leontopodium 

 alpinum, Thylacospermum, Sedum quadrifidum, Draba 

 alpina et himalaica Werneria nana. 



Tsaidam, nonnullis partibus, ut jam dixi, desertum 

 Gobicum referens, jugis montium altis undique protec- 

 tum, hanc ob causam suis locis plantis quamquam spe-
