5. A shorter inflorescence. 



6. A greater possibility of sell-pollination. 



The ordinary type contains 1\ aljiitui and the temperate 

 type 0Ï F. vulgaris, the arctic one, on the other hand, contains 

 F. villosa and the polar- type of F. vulgaris. 



As already mentioned, experimental cnlture alone will be 

 able to , prove whether the arctic characters are constant in 

 the plants in question. Hypothetically, I have suggested that 

 tilis will be found in F. villosa. In case such experiments 

 give positive results in regard to the main points as regards 

 F. vulgaris, we should be justified in classifying the arctic type, 

 here mentioned, as a special variety, named F. vulgaris, var. 

 arciica, but scarcely before this occurs. 



Postscript to the chapter on Morphology and 

 Biology. Since writing the previous chapter I have be- 

 come acquainted with the following description by Alice East- 

 wood in "A descriptive List of the Plants collected by Dr. F. 

 E. Blaisdell at Nome City, Alaska" (Botanical Gazette vol. 

 XXXIII, 1902, p. 293): 



'■'■ Finguicula arctica, n. sp. — Leaves rosulate, glabrous, 

 apparently fleshy, broadly ovate, sessile, obtuse, 1 — 2 cm. long, 

 5 — 8mm. wide; scape purple, glabrous below, glandular- 

 pubescent above, 1-flowered, 7 cm. high; calyx 2-lipped; upper 

 lip of 3 deltoid divisions half as long as the lip, the sinus 

 acute; lower lip narrower, with 3 shorter teeth and obtuse 

 sinus one-third as long as the division; corolla purple, 11 mm. 

 long, hairy within, with club-shaped hairs that extend to the 

 lobes of the upper lip; lobes 3, orbicular, 4 mm. across; lower 

 lip of 2 similar but shorter lobes; spur slender, tapering, 7 mm. 

 long ; stamens 2, with filaments dilated at base, nearly 2 mm. 

 long, surmounted by capitate anthers; ovary orbicular, glabrous; 

 stigma of 2 white broad plates, thin in texture.
