Nr. 3] SOME VASCULAR PLA NTS FROM SAGHALIN 11 



Majanthemum canadense Dksf. 



This spedes is usually noted, as for instance in the previously 

 mentioned work on the flora of Saghalin by Miyabe and Miyake 

 as a Yariety of Majanthemum bifolium Fr. Schmidt hut differs 

 nevertheless so distinctly from the form in question that Komarov 

 is certainly right in recording it (Flora Manshiiriae Pag. 474) 

 under Desfontaine's primary name. Besides being of coarser 

 growth, it has larger, entirely scentless flowers with distinctly 

 recuryate petals. The leaves are also thicker, fleshier, and more 

 glistening. 



In bud and flower 19 May. At moist places. 



Orchidaceae Juss. 



Orchis aristata Frisch. 



In full bloom 21 June. In moist thicket.

Tab. nost. IV. Fig. A. 



Cautis humilis 6 — 8 cm. altas tener, at tamen rigidus tennis 

 teres rectus eredus (neque curvatus flaccidus neque ascendens) valga 

 simplex pilis pias minus densis hrevihus curvafis deorsum directis 

 vestitus, colore suffusco vel saepe rubello. 



Volia semper sessilia anguste ovalia adulta vulgo 7 — 10, raro 

 ad 12 mm. longa et 2.5 — 4 mm. lata. Lamina uno nervo dorsali, 

 rarius etiam duobus lateralibus nervis conspicuis, praedita. Folia 

 erectissima semiamplectentia margine integro aliquantum revoluto 

 et sicut nervis paginae inferioris pilis brevibus aduncis firmis ad 

 basim folii directis vestito. Pagina inferior folii de cetera glabra, 

 superior e contrario plus minus dense pilosa et siccata utique 

 punctata. Flores vulgo singuli, raro bini. Pedunculi tenues erecto 

 crassi numquam flaccidi et vulgo tam breves, ut flos apicem foliorum 

 summarum vix superet, vulgo bracteolis binis parvis cymbiformibus 

 carinatis secundum nervum medium pilis brevibus aduncis obsitis, 

 praediti. Bracteolae tamen saepe desunt. Sepata apice plus minus 

 evidenter acuminata, 2 — 2.5 mm. longa, interdum margine mem-

 serie una pilorum brevium aduncorum rigidis erectis obsito praedita. 

 Petala angustiuscula aequalia — neque ovalia — apice paulatim

 sexta parte breviora dimidia inferiore parte pilosa et antheris flavidis.
