perties deserving of notice. The Lagerstrcemia R,egina, 

 a tree about 30 feet in height, and Lagerstrozmia Indica, 

 are common in our gardens, and rank among the most 

 showy of our ornamental plants. Lawsonia Alba, the 

 plant from which the Henna or Alhenna of the Arabs is 

 procured, known here as the Tree Mignionette, from the 

 powerful odour it exhales at night, is also very generally 

 cultivated. The berk and leaves of Lagerstrcemia 

 KeginvE are accounted purgative and hydragogue, and 

 the seeds narcoac.
