partly Imbricate and partly valvate; the sepals, too, are intermediate in 

 shai)e between those of the two species. Probably the plants raised from 

 seed sent by Wilson to Veitch in 1901 under No. 1254 were not quite uni- 

 form and may have represented different intergradations between the two 

 parent sj)ecies. Tlie i)lant w^hich is growing here, but has not yet flowered, 

 differs from the sixx^inien supposed to have been taken from the type 

 plant, somewhat in the pul>escence of the leaves, the central rays of the 

 stellate hau-s being less profusely developed than in that specimen. 



Deutzia parviflora IJunge var. ovatifolia, var. nov. 



A typo recedit foliis ovatis basi rotundatis vel truncatis, breviter acumi- 

 natis, 3.5-6 cm. longis et 2-3.5 cm. latis argutius minutiusque serrulatis, 

 corymbis satis densis 3-4 cm. diam, floribus flavescenti-albis. 



ClIIXA. 



W 



growing at the Arboretum from seed received under the same number; 

 type collected June 3, 1918, 



The typical form differs from this variety in its larger, usually elliptic- 

 ovate to oblong leaves, more or less cuneate at the base and rather irregu- 

 larly serrate with more spreading teeth, and in the larger and looser co- 

 rymbs of pure white flowers. The new variety looks rather distinct with 

 its smaller, ovate, broad leaves and the dense corymbs of creamy-white flow- 

 ers. Purdom*s No. 40 collected in different localities is not uniform and 

 consists only of flowering specimens.
