Ovules

Male and Female Tamarack Cones Maturing

Tamaracks, or American Larches (Larix laricina) are non-flowering plants (often found growing in bogs) that reproduce using seeds that are borne on the woody scales of cones.  Conifers (Tamarack is one of about 20 deciduous conifers, but the only one in New England) have both male and female cones.  The male cones produce pollen which is distributed by the wind and the female cones contain ovules which, when fertilized, develop seeds.

The male (pollen-bearing) cones look like little, round buttons (less than 1/5th of an inch wide), and consist of brown to yellowish pollen sacs with papery scales at their base. After maturing in early spring, they shed their pollen and then wither. The female cones of Tamarack are also small – less than ½ inch – and initially resemble tiny, maroon roses.  As in all conifers, the scales open temporarily to receive pollen, then close during fertilization and maturation, and then re-open again at maturity to allow the seed to escape.
