[1] | Lotova L. I., Timonin A. C. Anatomy of cortex and secondary phloem of rosaceae. 4. roseae and ulmarieae (rosoideae) // Ботанический журнал. — 1999. — Vol. 84, no. 3. — P. 33–43. The tribes Roseae and Ulmarieae differ in lots of characters. Whether the differences are due to different relationships of the tribes or to their dissimilar growth habits, is still not quite clear. Rosa and Hulthemia species seem to be too similar in their cortex and phloem anatomies to be segregated. Ulmarieae does share some cortex and phloem characters with herbaceous members of the subfamily Spiraeoideae. Key words: cortex, secondary phloem, Rosaceae, Rosoideae. |
