fistulose การใช้

• Souverbie in Souverbie & Montrouzier, 1875, with which it agrees in the perforated or fistulose spines.
• The cortex is relatively thin, 25 50 祄 thick, covering a fistulose ( hollow ) medulla.
• The cortex surrounds a fistulose to subfistulose medulla, varying from 55 175 祄 thick, generally thinner on the branches where a change in thickness appears related fragmentation branchlets that break off from primary branches.
• The species ( " N . lobulata " ) also recognized by containing sekikaic acid ( with triterpenes ), and by a relatively thin cortex, ( 0-) 35 75 (-100 ) 祄 thick, eroding near base, covering a fistulose medulla ( solid on Guadalupe Island ), which seems related to the contorted appearance of the branches.
