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 RACEMIFLORA, var. Vertcutt Rehder & Wilson, n. var. 
Cotoneaster acutifolia Veitch, New Hardy Pl. China, 1910, p. 5 (non Turc- 
zaninow). 
Varietati soongaricae Schneider affinis sed differt praecipue habitu virgato, 
folis acutis v. rarius acutiusculis mucronulatis ovalibus v. ellipticis 2-3.5 cm. 
longis subtus densius cinereo-villosis, floribus majoribus 13-15 mm. diam., calyce 
densius villoso, 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 Arboretum it forms an upright shrub with 
rather slender virgate branches covered in June along their whole length with 
white or slightly 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 em. longis, foliolis plerumque 11-13 obovatis v. 
Pintice obtusiusculis fere glabris v. subtus sparse tantum pubescentibus 2-5 mm. 
de » calyce glabro, sepalis triangulari-ovatis saepe obtusiusculis, et habitu magis 
080. 
Western Szech'uan: valley of Min River, around Mao-chou, alt. 1300-2000 
m., May and September 1908 (No. 1016, fruiting [type], and flowering; bush 1-3 m. 
tall, flowers white, fruits with purple bloom); valley of Tung River, July 1903 
(Veitch. Exped. No. 35189). 
This variety differs from the type chiefly in the much smaller glabrescent leaves, 
is 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 amphidoza 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, may be a juvenile form of an 
<verereen Photinia; the short-petioled elliptic to oblong leaves are coarsely and 
ly spinose-dentate and 5-7 cm. long. 
i Prunus discadenia (p. 200). On p. 201, line 4, after No. 62 instead of “ as to 
Owering branches . . .” read: as to fruiting branches, the flowering branches 
£ to P. laziflora Koehne);
