There is a very detailed article published in the Agronomy Journal
(vol. 43, no 3.) in 1951, by Joyner, Gangstad and Seale titled: The
Vegetative Propagation of Sansevieria.

This was a report on a study on the feasibility of commercial
production of Sansevieria during W W II . 

Their study involved cutting S.trifasciata and S. guineensis leaves in
thirds (base, middle, and tip) and also length-wise, leaving 1/8, 1/4,
1/3 sections.  

They state: "It is found that few roots and shoots are produced by the
basal sections.  The rooting is particularly poor.  More roots and
shoots are produced by the middle sections.  Tip sections produce the
most rapid and prolific growth."

The article also has pictures of Sansevierias in various stages of
root and stem growth (20, 60, 90 days), and chart monthly growth of
Sansevierias grown out of doors (Florida), which is the study's main
concern.

Again they conclude:  "It is seen from this graph that base sections
produce few plants and cannot be considered as suitable planting
material.  The midsections give a relatively good growth of plants
throughout the season.  The tip sections give the most prolific growth
at certain times of the year."

It is also this study which discusses the use of rooting hormones:
indolebutyric acid and indoleacetic acid, concluding the later is far
better.
