ROSACEAE. 165 



Spiraea cantoniensis Lour., Chinese Spiraea, Asiatic, commonly planted 

 for ornament, is a shrub about 5° high, with thin glabrous rhombic-lanceolate 

 serrate leaves 2V long or less, green above, pale beneath, the corymbose white, 

 often double flowers about *' broad. [S. Reevesiana Lindl.] 



Spiraea pninifolia Sieb. & Zucc, Plu^i-leaved Spiraea, also As-iatic, 

 recorded by Lefroy and by Verrill as grown in gardens, is similar to the pre- 

 ceding species, but has ovate or oblong leaves pubescent beneath. [,S'. japonica 

 of .Jones?] 



Spiraea salicifolia L., Meadow-sweet, European, also recorded as a gar- 

 den shrub by Jones, Lefroy and Verrill, has numerous pinkish flowers in dense 

 terminal pubescent panicles. 



Eoses (genus Rosa) are grown in j^rofusion and with great success in 

 many kinds, but do not spread beyond cultivation to any considerable extent, 

 although Lefroy records that a species doubtfully determined as Eosa laevigata 

 Michx. was naturalized in Pembroke Marsh and in the Walsingham tract. The 

 Green Eose is frequently seen, in gardens. 



Rosa bracteata Wendl., Asiatic, an evergreen species with single white 

 flowers and small entire leaflets, is commonly planted on walls. 



Rubus ellipticus Smith, Yellow Easpberry, Himalayan, a shrub with 

 densely bristly-hairy stems and petioles, and armed with yellowish curved 

 prickles, the canes nearly erect or arching and 10°-15° long, the leaves 3-5- 

 foliolate with ovate to broadly elliptic irregularly serrate leaflets H'-4' long, 

 whitish-puberulent beneath, the white flowers about i' wide, numerous in small 

 clusters; the yellow, edible fruit, 5"-6" long, has been planted for its fruit; 

 luxuriant plants were seen at Montrose in 1913. 



Rubus trivialis Michx., Southern Dewberry, of the southeastern United 

 States, is a trailing vine with bristly-hairy and prickly slender branches 5° 

 long or longer; the leaves have 3 or 5 glabrous, ovate, sharply serrate, short- 

 stalked leaflets 1-2 J' long; the white flowers, about 1' broad, are usually 

 solitary; the black, edible fruits are 6"-10" long. It has been planted for its 

 fruit, and was seen in a hedge at the Agricultural Station in 1913. 



Rubus Idaeus L., European or Garden Easpberry, a species with erect 

 prickly canes 2°-5° high, large clusters of small white flowers, producing the 

 well-known fruit, has been planted experimentally, but does not succeed well. 



Rubus fruticosus L., European Bramble, is recorded by Eeade as having 

 been introduced but did not thrive. 



Loganberry, of hybrid origin, seen at Echo PTeights in 1914, has long 

 prickly stems, 3-foliolate leaves, the leaflets broadly ovate, dark green above, 

 densely whitish-pubescent beneath; its dark red fruit is about 1' long. The 

 plants did not succeed. 



Schizonotus Lindleyanus Wall. [Sorharia Lindlcjiana Maxim.], Lindley's 

 SCHIZONOTUS, Himalayan, a shrub about 6° high, with pinnate leaves of 15-23 

 sessile, lanceolate, Incised, acuminate leaflets and large terminal panicles of 

 small white flowers, was grown at Wood Haven in 1914. 



The record, by Lefroy, of Geum radiaUim? Michx., North American, "a 

 common yellow-flowering weed in fields, ' ' is manifestly an error for some other 

 plant either in record or determination. H. B. Small also records it and com- 

 pares it with ''goat-weed" (Capraria hifiora) from which he says it differs 

 in having yellow flowers, but Geum radiatitm does not resemble Capraria. 



A double-flowered Genm, grown at Eose Cottage in 1914, flowered sparingly.
