NEW NORTHWESTERN PLANTS. 



By Edw. L. Greene. 



AcT/EA CAUDATA. Evidently tall, the stem probably solitary, 

 the young petioles and rachis villous-puberulent, the leaflets when 

 young minutely villous along the veins beneath, the upper face 

 sprinkled with minute rigid shining hairs more or less appressed : 

 leaflets from rhombic-ovate to lance-oblong, doubly and sharply 

 incised, but with a long lance-linear perfectly entire acumination : 

 raceme short, obtusely low-conical, its bracts ovate to ovate- 

 lanceolate, acuminate, of one-fourth the length of the pedicels : 

 petals 2 or more, of about two-thirds the length of the stamens, 

 the elliptic blade passing gradually into a flattened claw of its own 

 length : berries not seen. 



Margin of a rivulet, Chilliwack Valley, B.C., July 11, 1902, 

 J. M. Macoun, No. 33,550, at least in part, and as to the flower- 

 ing specimens; for the branches taken by Mr. Macoun later by a 

 few days, and at a lower altitude seem to represent a diff"erent 

 species, probably A. arguta, Nutt., the leaves of which are not at 

 all caudate-acuminate as in this new species and the next fol- 

 lowing. 



AcT^A ASPLENiFOLiA. Stems perhaps several from the root, 

 I 3^ feet high at early flowering, with leaf and inflorescence near 

 the summit ; a very sparse, somewhat villous hairiness along the 

 veins of the leaves beneath, and an equally sparse succession oi 

 minute rigid hair-points along veins and veinlets above; leaflets of 

 somewhat deltoid-lanceolate outline, incisely lobed and the lobes 

 serrate, the leaflet ending caudately as in the last : raceme very 

 short and few-flowered ; bracts thin, distorted, almost scarious ; 

 petals usually a, of less than half the length of the stamens, and
