demum 28 mm, longis, summa parte subulatis, infra dilatato- 

 complanatis post excussum pollinem flaccescentibus, plus minnsve 

 purpureo-notatae. Stylus subcylindricus robustus, longitudine 

 3*5 cm., diametro 5*2 mm., albido-pellucidus, sursum et ad oras 

 papillosi stigmatis purpureo suffusus. 



This fine Littaea was acquired during 1906 from the collection 

 of Mr. Justus Corderoy at Didcot, and has ' poled ' this spring in 

 the Succulent House at Kew ; the native country is not known 

 with certainty, but it is believed to have been obtained originally 

 from Central America. From Mr. Baker's group of ' Marginatae ' 

 it is at once distinguished by the extremely narrow border of the 

 leaf, and from all the ' Sub-marginatae ' except A.pumila, which is 

 otherwise a very different type, by the structure of the inflor- 

 escence, which rather approaches that of A. densiflora, Hook, in 

 Bot. Mag. t. 5006. From A. demiflora however it is very certainly 

 marked off by the margin-prickles, which in that are far closer 

 together. 



The nearest known form seems, by the description, to be the

flower spike, from the illustration (processed from a photograph), is 

 much longt and narrower, and the stamens are less conspicuous ; 

 the margin -prickles also in A. expatrkita appear to be larger and 

 more hooked than in the present species, and the surface of the 

 leaf is more concave. In the Kew plant the leaves approach those 

 of A. decipiens, Baker (a Euagave), in a tendency to be convex 

 above the base on the upper side, also in the colour, and tin 

 seems to be the case with A. demiflora also.
