Clue #23

O Tsuga Canadensis, protect me!
 

​I found this information from other hunters:

  • ​

 

Information I have found myself:

  • Tsuga canadensis, also known as eastern hemlock,[2] eastern hemlock-spruce[3] or Canadian hemlock

  • The eastern hemlock grows well in shade and is very long lived, with the oldest recorded specimen, found in Tionesta, Pennsylvania, being at least 554 years old.[5] The tree generally reaches heights of about 31 m (102 ft),[4] but exceptional trees have been recorded up to 53 m (174 ft).[6] The diameter of the trunk at breast height is often 1.5 m (4 ft 11 in), but again, outstanding trees have been recorded up to 1.75 m (5 ft 9 in).[7] The trunk is usually straight and monopodial, but very rarely is forked.[8] The crown is broadly conic, while the brownish bark is scaly and deeply fissured, especially with age.[4] The twigs are a yellow-brown in color with darker red-brown pulvini, and are densely pubescent. The buds are ovoid in shape and are very small, measuring only 1.5 to 2.5 mm (0 to 1⁄8 in) in length. These are usually not resinous, but may be slightly so.[4][8]

  • The leaves are typically 15 to 20 mm (0.59 to 0.79 in) in length, but may be as short as 5 mm (0.20 in) or as long as 25 mm (1 in). They are flattened and are typically distichous, or two-ranked. The bottom of the leaf is glaucous with two broad and clearly visible stomatal bands, while the top is a shiny green to yellow-green in color. The leaf margins are very slightly toothed, especially near the apex. The seed cones are ovoid in shape and typically measure 1.5 to 2.5 cm (5⁄8 to 1 in) in length and 1.0 to 1.5 cm (3⁄8 to 5⁄8 in) in width. The scales are ovate to cuneate in shape and measure 8 to 12 mm (3⁄8 to 1⁄2 in) in length by 7.0 to 10 mm (1⁄4 to 3⁄8 in) in width. The apex is more or less rounded and is often projected outward. Twenty-four diploid chromosomes are present within the trees' DNA.[4]
