(6) A. umhellatus caulescens. — A recently imported evergreen 

 form from the Cape, with creeping rootstock a foot long, distinct 

 stem some inches long, small foliage, but not distinct from the 

 type in the general aspect of the inflorescence, although the 

 exserted stamens seem distinct. 



(7) A. umbellatus repens(7). — A small-growing form with creep- 

 ing rootstock, narrow and short leaves and flowers like A. Moor- 

 eanus. A variegated-leaved form of this has been long in 

 cultivation. It grows slowly and demands a very dry soil. 



(8) A. umbellatus monstrosus. — A multipetalous form raised 

 from a 12-petalled flower. This is a most robust plant with 

 leaves 2 J to 3 inches wide and several hundred flowers to the 

 umbel. 



(9) A. umbellatus variegatus falcatus. — A garden form with 

 falcate leaves.

[Note. — The globose-shaped umbels, which have earned for some 

 forms the name A. globosus, are an individual and not a racial 

 character, and appear sporadically in the seedlings of all forms of 

 A. umbellatus.']

All these measurements are in inches. 



It will be noticed that it is only in A. Mooreanus, and in its 

 crosses, that the span of the flowers exceeds the limb. 



A. Inapertus. 



Rootstock creeping, stout, strictly deciduous. Stem about 

 3 inches high, curving to an erect pose from the creeping rootstock. 

 Leaves 8, stiff, erect, appearing before the flower scape and already 

 partly deciduous at the flowering period, glaucous, deeply channelled, 

 1 J foot long by 1 J inch wide. Scape 4 feet high, bearing an umbel 

 of less than 100 flowers. Pedicels very short, ij inch long. Flowers 

 erect in the bud, but hanging down perpendicularly on expansion, 

 which occurs in August ; deep blue in the tube, lighter blue in the 

 free segments, scentless, semi-patent, span £ inch. Tube, sub-cam- 

 panulate, J inch long. Segments, the free ends an inch long and the 

 entire limb 1 J inch long by J inch maximum width. Stamens shorter 

 than limb. Anthers black, pollen greyish, inconspicuous. Style not 

 exserted. Stigma entire. Fruit and seeds unknown. 



[Note. — This is not a moisture-loving plant like A. umbellatus, 

 and will withstand severe drought. In this respect it agrees with
