 Japan. I have seen only a few Japanese specimens without locality or collector

 termined by Miquel erroneously as his P. subhirtella. 



70. Prunus taiwaaiana Hayata in Jour. Coll. Sci. Tokyo, XXX. 87 (1911), 

 Formosa. Not known to me. Hayata says; "somewhat like P. penduZa, but 



distinguishable by the smaller flowers with narrower and more deeply emarginate 

 petals." 



71. Prunus microlepis Koehne, n. sp. 



Rami annotini tenues (an penduh?), pallide fuscescenti-cani, glabri; gemmae 

 circiter 3 mm. longae, anguste ovato-conicae, glabrae, solitariae v. ternae tunc 

 media foliifera, laterales floriferae (ut in Microceraso). Folia sub anthesi 5-7 

 mm. longa; dentes sub lente vahda longiores quam latae, multae bifidae, omnea 

 obtusae omnino eglandulosae, saepe incurvae; lamina supra pilis rigiduhs con- 

 epersa, subtus nonnisi in nervis pilosa. Involucra parva, circiter 5 mm. longa; 

 pedunculus 0-5 mm. longus; flores (l-)2 umbellati, praecoces; bracteae spathu- 

 lato-rotundatae, circiter 3-4 mm. longae, glanduloso-fimbriato-serratae, herbaceae; 

 pedicelli 10-16 mm. longi, glabri v. pilis paucis tenerrimis conspersi; cupula 5 

 mm. longa, campanulato-tubulosa, glabra v. subglabra; sepala ovata obtusa, 

 3.5 mm. longa, Integra; petala rotundata, 7 mm. longa 6 mm. lata, leviter emar- 

 ginata; stamina 35, petaUs subbreviora, ad 5 mm. longa; stylus stamina paullo 

 euperans, glaber. 



Hondo: prov. Senano, a. 1864, Tschonoski (Maximowicz, Iter II.), determined 

 by Maximowicz as P. pendula, mixed with var. ternata. 



Differs from P. pendula Maximowicz by the obtuse serratures of the leaves, 

 the shorter and broader sepals, the small petals, the more numerous stamens 

 shghtly shorter than the petals and the glabrous style. 

 Prunus microlepis, var. temata Koehne, n. var. 



Rami intense fusci; gemmae ternatim ramulos vix 3 mm. longos terminantes, 

 media foliifera, laterales floriferae. Flores sohtarii; pedicelli 5-6 mm. longi; cupula 

 6 mm. ; sepala late ovata, hinc inde intus pilosa tenereque breviter ciliata, 2 mm. 

 longa; petala 8 mm. longa 6 mm. lata; stamina 41, ad 6 mm. longa; stylus stamini- 

 bus subbrevior. 



Hondo: Tschonoski (with the type, determined by Maximowicz as P. pendula).
