146 Eastwood : Some small-flowered Species of 





plant is characterized by a roughness caused by the pustules at 



the bases of the hairs. 



The specimens from which the description is made were col- 

 lected by John Macoun in the vicinity of Vancouver, May 6, 1893 



(no. 667). 



8.' Nemophila micrantha sp. nov. 



Stems becoming long and lax, decumbent or supported by 

 other plants, some of the stems 3 dm. long, winged, more or less 

 retrorsely hispid : internodes 2 or 3 times as long as the leaves, 

 1-14 cm. : leaves opposite, various, regularly or irregularly 3-5- 

 lobed, with the lobes dentate or entire, broadly ovate in outline or 

 one-sided, cuneate at base ; lowest leaves with the two lowest di- 

 visions petiolulate, surface hispid with regularly appressed hairs 

 which are more abundant on the lower surface : petioles equalling 

 or shorter than the blades, dilated and connate-clasping at base : 

 flowers from the lowest axils with peduncles that elongate and 

 are recurved in fruit, generally shorter than the subtending leaves : 

 calyx with triangular-subulate divisions about 2 mm, long, veiny, 

 very hispid externally, slightly so on the inner surface : auricles 

 very short, spreading : corolla tubular-campanulate, 3 mm. long, 

 divisions shorter than the tube, retuse at apex ; appendages con- 

 sisting of a pair of narrow scales which are ciliate along the free 

 edge : stamens inserted a little above the base of the corolla, 

 about as long as the tube : anthers small, heart-shaped : ovary 

 and lower part of style very hispid, the latter divided about to the 

 middle : capsule containing 2-4 orbicular seeds with deciduous, 

 stipe-like calyptra ; the surface of the seeds obscurely corrugated 

 and minutely pitted. 



This grows in shady places under brush and trees in the re- 

 gion of Sequoia sempervirens. Specimens examined from Mount 

 Tamalpais, Lagunitas, Mill Valley, Fairfax, all in Marin County, 

 and collected by the writer, from March to August ; Big Tree 

 Grove, Santa Cruz Mountains, collected by Mrs. Brandegee, May, 

 1887. No. 742 of the collection of H. E. Brown, from near 

 Mendocino, is probably the same species but differs somewhat 

 from the form common in Marin County. 



There seems to be some variation in the size of the leaves and 

 the flowers, but in the main the distinguishing characteristics are 

 constant. The appendages on the corolla tube are difficult to find, 

 being very small and thin. They are attached by the shortest 

 side, the free part of each pair being linear-subulate and inclined 

 towards the other.
