I78 GREENE 



It may not perhaps be determinable to a certainty that the 

 preceding rather than this, was grown in London, and formed 

 the type of Dillenius' figure of leaves and staminate panicle. 

 But Banister's field, and probably that of Catesby also, by both 

 of whom seeds were sent to England, was the lower country, 

 where only what I have here called Rhus glabra is found. 



3. RHUS AURICULATA, sp. nov. 



More slender than R. glabra, all the parts somewhat smaller, 

 the fruiting panicles especially only about one-third as large : 

 leaves 2.5-3.5 dm. long; leaflets about 19, approximate, often 

 alternate, 7-10 cm. long, never more than 2 cm. in width, often 

 less, of linear-lanceolate outline, the apex caudately long-atten- 

 uate, the sessile base showing definite though small auricles, 

 the serratures light but rather close, 14-18 on a side, texture 

 subcoriaceous, the upper face light green, transversely rugose, 

 the somewhat sunken veins correspondingly prominent on the 

 very glaucous lower face ; fruiting panicles oblong or slightly 

 verging toward the pyramidal, 10-13 cm ' high 5 drupelets com- 

 paratively few, large. 



A remote southwestern ally of R. glabra, with very definite 

 specific marks. It is known to me only as collected by Mr. C. 

 L. Pollard, August 11 to 12, 1896, the special locality, Agri- 

 cultural College, Oktibbeha County, Mississippi. The type 

 specimen occupies sheet 271931 of the National Herbarium. 

 There is a duplicate in Herbarium Field Museum which I have 

 seen. Mr. Pollard's distribution number 1261 is on these two 

 of his labels that I have seen. 



The species must quite surpass R. glabra in beauty. Its 

 narrow slender-pointed leaflets seem to droop from the rachis 

 rather than to spread away from it horizontally. This, how- 

 ever, is characteristic of several other allies of R. glabra belong- 

 ing to regions lying westward. 



4. RHUS ITHACENSIS, sp. nov. 



All the parts smaller and more slender than in R. glabra, the 

 branches not glaucous, seldom glaucescent : leaflets 13-17,
