granular mucous contents : the cells are arranged in only one 

 row. This layer is well seen in Astragalus hamosus, Sesba- 

 nia cannabina, &c. In the second layer there is a ninnber of 

 variously formed cells, constituting the great bulk of the 

 albumen ; these are succeeded by a third row placed next the 

 cotyledons, which are small and without granular contents. 

 In the middle layer the cells are either very sharply defined 

 walls, or they arc lost in jelly. The former are most common 

 in PapilionacccC, the latter in Csesalpinese. When the walls 

 of the cell are evident, jelly is found in the inside of the cell, 

 often obstructino- the entrance of the light, as in Sesbania 

 cannabina, &c., it is entirely obstructed in Securigera coro- 

 nilla. Frequently the cavity of the cell presents a star shape, 

 from the formation of pores in the jelly, or gelatine, as in 

 Cytisus, Laburnum, &c. Intercellular spaces are seen in 

 Amorpha fruticosa, S:c., which are also filled with jelly. 

 These form a transition to those in which the cells are entirely 

 embedded in jelly, as Gleditschia triacanthos. The walls 

 are not to be distinguished but by dropping on them sulphuric 

 acid, by which means the jelly is dissolved out. The interior 

 of the cells is filled with mucus (Schleim), a term used to 

 distinguish it from jelly and starch. This mucus is composed 

 of globules, which are coloured brown yellow by tincture of 

 iodine. In Cassia fistula resinous globules were found, and 

 in Mimosa pudica, crystals in the same position. This jelly 

 or gelatine between the cells, seems to be identical with 

 Mohrs intercellular substance, and it may be conjectured to 

 be the basis from which the cells of the albumen them- 

 selves are formed. 



49. CALLIPSYCHE eucrosioides. 



We have been favoured by the Hon. and Very Rev. the 

 Dean of Manchester with the following definition of a new 

 genus of Amaryllidaceous plants, which has produced its 

 flowers in the garden at Spofforth. 



CALLIPSYCHE. [Subord. Amaryllide^, § Pancratiformes,] Germen
