There is still much confusion regarding the distribution of this 

 species and T. purpurascens. Collectors would confer a favor by 

 gathering fruit as well as flowers. " This species is never glandular, 

 so that all specimens with glandular pubescence are apparently refer- 

 able to T. purjiurascens." 



(SOST.) T. venulosum, Trelease, Proced. Bos. Soc. Nat. Hist., 

 XXIII., 3(12. 

 " Glabrous and glaucous, the stem, petioles and sepals purple-tinted, 

 the foliage typically pale or whitened. Stem simple, erect, 7-20 

 inches high. Stem leaves 2-3, long petioles, 3-4 ternate. Leaflets 

 approximated, short stalked, moderately firm, rounded and lobed at the 

 apex as in T. dioicum, the lower surface rugose-veiny. Panicle simple, 

 narrow, its short erect branches few-flowered. Flowers dioecious, 

 small. Sepals ovate. Stamens 10-20, on slender filaments; anthers 

 oblong, slender-pointed. Achenia about eight, nearly sessile, 4 mm. 

 long, ovoid tapering into a straight beak ; thick-walled and otherwise 

 similar to those of T. dioicum except that they are two-edged and 

 commonly with one less groove on each side. Stigma sagittate. Seed 

 ovid, pointed at one end, 1X2 mm., filling the ovary." British 

 America. (Franklin Expedition.) Saskatchewan region. {Bourgeau. )

All references to Vancouver Island specimens are placed here. 

 This species is quite common in the neighbourhood of Victoria, Van- 

 couver Island, in damp spots in pasture fields. Dr. Gray places this 

 variety under M. apetalus, Gay, but I prefer Prof. Greene's opinion in 

 Bull. Torr. Bot. Club, xiii., 61, that it should be placed under M. minimus.
