species, the latter with ten, one of which is new. George V. Nash” has pub- 
lished a new genus of grasses, Blepharoneuron, a monotypic genus based 
upon Vilfa tricholepis Torr. G. N. Best™ has described a new genus of 
_mosses, Fabroleskea, based upon Leskea Austini Sulliv. Edward L. Greene* 
has described several new species of Composite from a collection made by 
E. O. Wooton in southeastern New Mexico, among which is a new genus, 
Wootonia, “ about equally allied to Bidens and Cosmos.” L, M. Underwood” 
has published a discussion of Se/aginella rupestris and its allies, in the course 
of which he describes six new species. John K. Small,’ in continuing his 
descriptions of numerous new species from the southern United States, pro- 
poses a new genus of Paronychiacee, Forcifel/a, based upon Siphonychia 
Rugelii Chapm. E.O. Wooton” has described an interesting new rose from 
New Mexico, 2. ste//ata, which is the second member of a hitherto mono- 
typic section (MINUTIFOLI#) of the genus. Edward L. Greene,® in recent 
folios of Pittonia, has published as follows: Results of a study of the 
Macoun Canadian collection of the species of Antennaria, fifteen new species 
being described, to which are appended three other new species of the genus 
from the southwest ; a new genus of the Senecionide, Razmiera, based 28 
Prenanthes stricta Greene (Luina Pipferi Robinson, Psacalium strictum 
Greene); seven new species of Erigeron; the establishment of the aa 
Microsteris, based upon Coldlomia gracilis Dougl., from which six additional 
species are segregated ; and the establishment of the genus Gymmnosterts, 
upon Collomia nudicaulis Hook. & Arn.— J. M. C.

Epwarb L. GREENE” calls attention to the occurrence of “ at 
genesis" in Antennaria plantaginifolia, as well as in some of the epee 
cleistogamous flowers of Viola. Of course he only means the setting of § ; 
without pollination, but the observation suggests a profitable ee 
investigation for the morphologist. It is hardly likely that it 1s a ome 
parthenogenesis, for this has been disproved for all such claims mene 
higher plants, but it is always interesting to know the origin of ae 
tively developed embryos.— J.
