The present is, we believe, the first season that the 

 flowers of any of the genus have been seen in our gardens. 



From outward appearance, the two species we have seen, 

 would be without hesitation ascribed to Pancratium; yet 

 dissection displays in their one-celled fruit a neater and 

 better defined distinction than has been yet obtained for any 

 other group of this order. This circumstance was first ob- 

 served by Mr. Brown, and has been made the foundation 

 of Calostemma. The difference induced in habit is slight, 

 but still manifest; the corolla is smaller than in Pancra- 

 tium, the segments of the limb converge campanulately, 

 and do not extend themselves radiately as there; these are 

 likewise obversely oblong, not tapered upwards as in most 

 Pancratiums, and approach in this respect nearer to those 

 of Narcissus. The coronal web is narrower between the 

 stamens than it generally is in Pancratium.
