who figures typical R. Maximo wicziana on plate I of part vn of his Flora 

 sylvatica koreana. The only difference which remains now between the 

 two forms is the absence of bristles on the stems and branches in R. Jackii 

 which certainly cannot be considered a specific difference. 



Rosa omeiensis f . chrysocarpa, forma nov. 



A typo recedit fructu luteo majore. — Frutex ramis aculeis basi valde 

 dilatatis armatis, turionibus insuper dense aciculate-setosis: folia ramulo- 

 rum pleraque 5-juga, turionum 6-7-juga foliolis glabris; fructus stipite 

 carnoso parti superiori subaequilongo incluso circiter 2 cm. longus et 

 11-12 mm. diam. 



Raised from seed sent from western China by E. H. Wilson to the Arnold 

 Arboretum in 1908 or 1910; specimens collected in Hort. EL S. Hunnewell, Welles- 

 ley, Massachusetts, by Mrs. S. D. McKelvey, August 8, 1922. (type). 



This form differs in its bright yellow fruits from typical R. omeiensis 

 Rolfe which has the fruits entirely red or sometimes red with the stalk- 

 like stipe colored orange. The lighter and brighter color of the larger 

 fruits makes this form even more conspicuous at fruiting time than the 

 red-fruited type, though unfortunately the fruit of R. omeiensis which 

 ripens early in July and a month later in the yellow-fruited form drops 

 soon after ripening and therefore the display does not last long. 



Hamamalis virginiana L. f. rubescens, forma n. 



A typo recedit petalis praeserlim basin versus rubescentibus. 



Originated at the Arnold Arboretum; type specimen collected Oct. 31, 1921, 



C. Vandervoet 



Tins form differing in the light red flowers from the type was first noticed 

 in the autumn of 1921 by Mr. C. Vandervoet on an old plant probably 

 brought from the woods in eastern Massachusetts and now growing in 

 this Arboretum. When in full bloom this red-flowered form contrasts 

 conspicuously with the typical form with its pale yellow flowers. The 

 form is, however, not entirely new, for a shrub with light red flowers 

 had been observed more than 30 years ago near Maiden, Massachusetts, 

 by Edward L. Rand (Sargent, Silva X. Am. V. 4, [1898] ). 



In the color of its flowers H. virginiana f. rubescens resembles the Japa- 

 nese //. incarnata Makino, a species flowering in winter and early spring 

 closely related to //. japonica Sieb. & Zucc, but in that species the sepals 

 are deep red on the inner surface, while in our form they are yellowish 

 green to brownish green.
