A few of these branches,however, instead of taking this course, pursued an almost horizontal course totheir very tips, which were sometimes 3 feet from the tap. These laterals forthe first few inches of their course as they left the tap-root were very sparselybranched, the distance depending upon the size of the root. Beyond thatpoint the branches gradually became more numerous and as one approachedthe extremities the number was so great as almost to form a conspicuousnetwork in the fight sand. As the main laterals and their larger branchesapproached their lower extremities, the little rootlets were so numerous as toform fairly brushy tips. Below 3 feet the branches of the tap were muchfewer in number and much larger in size. As a rule they seem to occur in THE ECOLOGICAL RELATIONS OF ROOTS.Text Appearing After Image:Fig. 24.—Eriogonum microthecum.Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
Summary[edit] Description: A tree for all uses, the Pecan tree serves as the nation's most important commercial nut producer while its prized wood is also used for furniture and flooring. Our tree doesn’t produce fully developed pecans as the regional growing season is not long enough, but it is the tallest tree on campus standing at 115 feet.
