Macleanica were collected in December, 1838, by John 

 Maclean, Esq. of Lima, in his excursion across the Cordillera 

 on the western slope, and obligingly sent by him to Spofforth, 

 together with several others of equal interest.

A bulb of this new species of Ismene, found by J. Mac- 

 lean, Esq. on the Quebrada de San Mateo at the elevation of 

 10,984 feet, flowered in the greenhouse at Spofforth in July, 

 1839, having been potted in white sand with a small admix- 

 ture of light loam, in consequence of the bulbs having been 

 recognized as a species of Ismene by their appearance. It 

 forms a connecting link between the original species of 

 Ismene and the genus Elisena, by the adpression of its cup to 

 the lower segments of the limb, and the greater length of the 

 filaments, of which the three upper instead of dipping into 

 the cup lie across its mouth. Elisena longipetala has pre- 

 cisely the growth and habit of an Ismene, and a bulb of 

 rino-ens (P. ringens of Ruiz) lately received from Lima, has 

 entirely the aspect and habit of I. calathina, with a sheathing 

 column, contrary to the representation in the Flora Peruviana. 



A variety of I. arnancaes has the lobes of the cup united, 

 so as to form an entire margin, projecting beyond the point 

 of the insertion of the filaments. It seems therefore very 

 probable, that, when better understood, the genus Elisena 

 will merge in Ismene. Every Ismene delights in white 

 sand, every Hymenocallis in strong alluvial soil, and immer- 

 sion in water. — W. H.
