CORRECTIONS AND ADDITIONS TO VOLUME I 431 



Cotoneaster gracilis (p. 167). Add the following: 

 Western Hupeh: without precise locality, A. Henry (No. 7918). 

 Henry's number had been referred by mistake to C. Zabelii, but it certainly belongs 

 to C. gracilis; it has red fruits 6 or 7 mm. long. C. gracilis is apparently closely 

 related to C. Zabelii and there are intermediate forms, as Wilson's No. 2174, which 

 has the leaves glabrous above like C. gracilis, but a pubescent calyx. 



Cotoneaster racemiflora (p. 168). Add the following variety: 



Cotoneaster racemifloka, var. Veitchii Rehder & Wilson, n. var. 

 Cotoneaster acutifolia Veitch, New Hardy PI. China, 1910, p. 5 (non Turc- 

 zaninow) . 



Varietati soongaricae Schneider afhnis sed diflFert praecipue habitu virgato, 

 foliis acutis v. rarius acutiuscuhs mucronulatis ovalibus v. cUipticis 2-3.5 cm. 

 longis subtus densius cinereo-villosis, floribus majoribus 13-15 mm. diam., calyce 

 densius viUoso, fructu majore subgloboso 8-12 mm. diam. purpureo, pyrena 

 plerumque una, 5-6 mm. diam. longitudinaliter irregulariter sulcato, hypostylio 

 trientem pyrenam obtegente. 



Western Hupeh: Hsing-shan Hsien, 1900 (Veitch Exped. Seed No. 1079; 

 plants growing in the Arnold Arboretum, specimens collected June 5 and Novem- 

 ber 7, 1916, type). 



This variety is closely related to var. soongarica Schneider, which differs in 

 its more divaricate irregular habit, obtuse leaves more thinly pubescent beneath, 

 smaller flowers and in its smaller bright red fruits with usually 2 stones. As C. 

 racemiflora, var. Veitchii grows in this Arboretvun it forms an upright shrub with 

 rather slender virgate branches covered in June along their whole length with 

 white or sUghtly pinkish flowers followed in autumn by dark red fruits. 



Osteomeles Schwerinae (p. 184). To this species add the following variety: 



Osteomeles Schwerinae, var. microphylla Rehder & Wilson, n. var. 



A typo recedit foliis circiter 1.5 cm. longis, foUohs plerumque 11-13 obovatis v. 

 ellipticis obtusiuscuhs fere glabris v. subtus sparse tantum puboscentibus 2-5 mm. 

 longis, calyce glabro, sepalis triangulari-ovatis saepe obtusiuscuhs, et habitu magis 

 dxunoso. 



Western Szech'uan: valley of Min River, around Mao-chou, alt. 1300-2000 

 m.. May and September 1908 (No. ioi6, fruiting [type], and flowering; bush 1-3 m. 

 tall, flowers white, fruits with purple bloom) ; valley of Tung River, July 1903 

 (Veitch. Exped. No. 3518"). 



This variety differs from the type chiefly in the much smaller glabrescent leaves, 

 the glabrous calyx with shorter lobes and in its denser more compact habit. 

 Wilson's No. 3518* is intermediate between the variety and the type, but seems 

 closer to the variety. 



Photinia (p. 190). After Photinia amphidoxa insert: 



Photinia spec. 



Western Szech'uan: Taning Hsien, thickets, alt. 1000-1300 m., July 1910 

 (No. 4619; bush 1.3-2 m.). 



This specimen, which consists of leafy shoots only, maybe a juvenile form of an 

 evergreen Photinia; the short-petioled elliptic to oblong leaves are coarsely and 

 irregidarly spinosc-dentate and 5-7 cm. long. 



Prunus discadenia (p. 200). On p. 201, line 4, after No. 62 instead of " as to 

 flowering branches . . ." read: as to fruiting branches, the flowering branches 

 belong to P. laxiflora Koehne) ;
