also belongs to B. declinata. The following form I wish to describe as a 

 rather distinct variety apparently of the same origin.

 1-6 mm. longum attenuata, margine fere semper densissime graciliter 

 serrulata serraturis 0.2-O.7 mm. longis inaequalibus circiter (4-)5 pro 

 5 mm., minimis exceptis 2.5 : 1 ad 3.5 : 1.5 vel ad 4 : 2 cm. magna petiolis 

 exclusis, superne saturate viridia, subtus laete viridia vel interdum paullo 

 pruinosa, utrinque (subtus distinctius) satis anguste elevato-reticulata, 

 (margines cellularum epidermidis paginae superioris valde undulatae 

 inferioris minime vel indistincte undulatae); folia ramulos novellos ful- 

 cientia surculorumque similia vel magis lanceolata, acutiora, apice longius 

 mucronulata, basi sensim attenuata, margine satis distincte et interdum 

 sinuato-spinuloso-serrata, dentibus interdum ad 3 mm longis, utrinque 



minora 2 : 0.6, majora ad 4-5 : 1 cm. magna petiolo ad 6 mm. 

 longo incluso, subtus pruinosa, glaucescentia, utrinque laxius reticulata. 

 Iuflorescentiae racemosae, inferne nudae, vel versus apicem ramuli breviter 

 racemosae, 4-5 mm. longae, circiter 8-18-florae, pedicello fructifero 4-7 

 mm. longo, bractea late lanceolata acuta vel breviter acuminata 1-1.5 (-2) 

 mm. longa suffulto; flores ut videtur pallide lutei, extus rubescentes, satis

This form came to the Highland Park at Rochester, N. Y., as B. actin- 

 acantha from Spaeth's nurseries at Berlin. I received specimens collected 

 on June 8, and October 15, 1907 and October 12, 1916, under no. 25 which 

 is the type of the variety, and no. 23 which is a form slightly more like 

 typical B. declinata. The variety is conspicuous by its relatively 

 acute leaves which are very finely and densely serrate on the flowering 

 branches while those of the shoots have a wider and coarser serration and
