444 CORRECTIONS AND ADDITIONS TO VOLUME I 



When I described M. Zemanii I overlooked Sprague's species, of which Henry's 

 No. 3117 is a type. This number had been referred to M. Fortunei (Lindley) 

 Mouillefert by Fedde, whom I followed, not having seen that specimen. 



Mahonia decipiens (p. 379). I now regard this name as a mere synonym of M. 

 Sheridaniana Schneider. The ovary apparently has no style, and there is a pair 

 of very small leaflets present at the base of the petiole on another specimen of 

 Wilson's in the Herbarium of this Arboretum. 



Mahonia Fortunei (p. 380). The author of the combination is Mouillefert, 

 Traite Arb. Arbnss. I. 165 (1892). 



Mahonia japonica (p. 382). The citation of the second synonym should read: 

 Berberis japonica Sprengel, Syst. II. 119 (1825). R. Brown in Tuckey, Narr. Exp. 

 Congo, App. V. 441, in adnot. (reprint p. 22) (1818 [not 1816]) only mentions that 

 Ilex japonica Thunberg has to be referred to Berberis, but he does not make the 

 combination. See also Nees v. Esenbeck, R. Brown's Verm. Bot. Schrift. 1. 230 

 (1825). 



Mahonia nepalensis (p. 382). Read "Mahonia napaulensis." 



Mahonia Veitchiorum (p. 383). This species has to be referred as a synonym to 

 Mahonia polyodonta Fedde. The distinguishing characters given by me in the 

 key on p. 381 have proved unrehable. 



Mahonia Sheridaniana (p. 384). See note above under M. decipiens. 



C. S. 

 Liriodendron chinense (p. 410). Add the following number: 

 Western Hupeh: Ichang Fu, rare, ah. 1000-1500 m., 1907 (No. 701; tree 

 8-20 m. tall; seeds only). 



Corylopsis Willmottiae (p. 425). This species flowered profusely in the spring of 

 1916 in this Arboretum, which enables us to add the description of the flowers: 



Flores pallide flavi in racemis densis multifloris cum pedunculo villoso v. fere 

 glabro 5-7 cm. longis, rhachi villosa; bracteae suborbiculares v. late ovatae, rotun- 

 datae, margine villosae, extus glabrae, intus plus minusve villosae, basales magnae, 

 florales minores circiter 5 mm. latae et 4 mm. longae, interdum margine irregulariter 

 et sparse erosae; bracteolae obovatae v. ovales, circiter 3 mm. longae; sepala late 

 ovata, 1-1.5 mm. longa, glabra, tubmn subaequantia, petale irregulariter orbicu- 

 laria, e basi truncata in unguiculum brevem contracta, lamina plerumque paulo 

 latiora quam longa, 4-5 mm. diam.; nectaria sepahs paullo breviora v. subaequi- 

 longa, plerumque ultra medium bifida, apice truncata v. irregulariter lobulati; 

 stamina petahs paulo breviora, circiter 3.5 mm. longa, filamentis basin versus 

 dilatatis; styU erecti petala fere subaequantes. 



Corylopsis plat3rpetala, var. levis (p. 427). This variety has also flowered in the 

 spring of 1916 and we add the following description of the flowers: 



Flores pallide flavi, in racemis cum pedunculo 3-5 cm. longis, rhachi villosa; 

 bracteae basales obovatae v. obovato-oblongae, acuminulati, extus glabrae, intus 

 sericeo-villosae, florales oblongo-ovatae concavae, circiter 5 longae et 2.5 latae, 

 extus sparse villosulae et minute glandulosae, intus villosae; bracteolae oblongae; 

 sepala ovata v. triangulari-ovata, interdum acutiuscula, 1-1.5 mm. longa, glabra; 

 petala suborbicularia, e basi truncata v. late cuneata in unguiculum brevem at- 

 tenuata, lamina paulo latiora quam longa v. aeque ac longa quam lata, 3^ mm. 

 diam.; nectaria apice tantum biloba et irregulariter lobulata, interdum bifida,
