Outside the stele lies the endodermis, which is the innermost cell layer of the cortex. The concept of the stele was developed in the late 19th century by French botanists P. E. L. van Tieghem and H. Doultion as a model for understanding the relationship between the shoot and root, and for discussing the evolution of vascular plant morphology. [2]
The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...

The endodermis is the boundary between the cortex and the stele. In many seedless plants, such as ferns, the endodermis is a distinct layer of cells immediately outside the vascular cylinder (stele) in roots and shoots. In most seed plants, especially woody types, the endodermis is present in roots but not in stems.
Scientists have found the U.K.’s largest dinosaur footprint site ever.. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
I created the plant biology text currently in Stele. Originally both stele and stela pages talked about stone slabs. I combined thos two but didn't add any text. To my knowledge stele and stela can both refer to inscribed stone slabs but only stele is also a concept in biology. --Chino 05:59, 4 Nov 2004 (UTC)
