Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin â¦ space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall.
Germinating the Seeds. To germinate staghorn sumac seeds place them in a warm room away from direct sunlight. Regularly mist the soil in the pot with a spray bottle to keep it moist. After germination, remove the plastic wrap and position the pot in a sunny window so the seedlings can grow.
Plant the staghorn sumac seed in spring after all threat of frost has passed. Plant each seed 1/2-inch deep. Plant neighbouring seeds 1 inch apart. Since staghorn sumac has such low germination rates, plant your entire supply of seed, or up to 100 seeds per square foot of seed bed.
