Hi all, I was looking through B&T Seeds list of carnivorous plant seed offering and they had Tsuga dumosa listed there. It is a member of the pine famiily and is used for furniture makiing in the Himalayas. I have seen the name before but am still unfamiliar with it. Have any others come across this name? Do any of you know why it might be listed a carnivorous?

You might be right on that Lloyd, could be the conifers got mixed in with the carnivores. Maybe I'll drop B&T a line and inquire about that, when I get some time.

Heres the actual information about tsuga dumosa.(From Wikipedia)
T. dumosa is a tree growing 20 to 25 meters (65 to 80 ft) high and exceptionally to 40 m (130 ft). The diameter at breast height is typically 40 to 50 cm (16 to 20 in), but can be beyond 100 cm (40 in).[2] The crown on small trees is ovoid and their form is like that of pendulous bushes. Older trees tend to have multiple stems from one or two sinuous boles, especially in cultivation. The crown of mature trees is broad, irregular-pyramidal and open. The bark is a similar to that of an old larch: somewhat pinkish to Grey-brown and heavily ridged with broad, shallow, flaky fissures.[3] The branches are oblique or horizontal. The twigs are reddish brown or grayish yellow in their first year and are pubescent, i.e. covered with short hairs. Branches that are 2 to 3 years old are grayish brown or dark grey with leaf scars. The wood from the tree is a brownish yellow with a fine structure and straight veins.[2]
The leaves are spirally arranged, pointing forward on the branches and placed distantly from one another compared to other species in the genus Tsuga. They are linear in shape, and 10 to 25 mm (0.5 to 1 in) long by 2 to 2.5 mm (0.07 to 0.1 in) wide. The ends are obtuse or rounded, and very occasionally emarginate. The upper surface of the leaves is green and shiny, while the undersides have 2 wide silvery stomatal bands. The upper half of the leaves usually have small dents on the margins, i.e. the margins are rarely entire. The midrib is concave on the upper surface. [2][3]
The staminate flowers are globose in shape, solitarily arranged and axillary. The anthers are a green-yellow in colour and they lack an air sac. The pistillate flowers are round-ovate in shape, also solitarily arranged, terminal and slightly down-curved. They have many spiral scales with 2 ovules contained within each scale. The seeds are about 9 mm (0.4 in) long, ovate in shape, brown in colour and have thin wings in their upper parts. Flowering occurs from April to May and fruiting from October to November.[2]

white pine was found to be sorta carnivorous a few years ago, feeding on some microb's in the soil with the help of a type of symbiotic fungus , But Tsuga's are a seperate family from pinus , but the same thing might be occuring ?
