For this new species of Agave I am indebted to James 

 Bateman, Esq. who received it from his friend Mr. Skinner. 

 The latter gentleman, travelling in Peru, found it growing 

 on a sandy plain, and learned that it is used as a soap plant, 

 its thick succulent tap-root possessing the property of form- 

 ing a lather with water. It has dingy purple flowers, and is 

 nearly allied to Agave lurida.

142. POLYSTACHYA ramulosa. 



T.ramulosa; ebulbis, foliis , scapo paniculato, floribus glaberrimis, 



sepalorum basi conica elongata, labello cuneato trifido apice carnoso mar- 



A native of Sierra Leone, whence it was imported 

 Messrs. Loddiges, who flowered it in September, 1838. 

 IS a small green-flowered plant with the habit of Polystachya 

 luteola, but more branched, and with branchlets at the base 

 of Its ramifications. The smooth flowers prolonged at the 

 apex (that is to say|at the base of the sepals) into a long 

 cone, and the wedge-shaped naked lip, distinguish this from 

 the other species previously known. The apparatus connected 

 with the pollen-masses is very, remarkable in this plant ; the 

 masses are two waxy bodies obliquely divided half-way into 

 two very unequal lobes, and adhering to a long white wedge- 

 shaped separable process, which has all the appearance of 

 the caudicula of a Vandeous oenus, and which is moreover
