Stems: green in 5 plants, brown in 1 plant, red in 4 plants, glaucous in 2 plants. According to RYDBERG’S key the plants would be classified from leaf characters as: R. fendleri, 3 plants; R. macounii, 6 plants. Only 2 flowered in 1931 and both had 50% of the pollen shriveled.
   Culture 12220 (38 offspring). Parent: R. pyrifera; Reno, Nevada. Height: about 1 m., 33 plants; less than 5 dm., 5 plants. Stem color: dull brown, 36 plants; red, 2 plants; glaucous, 15 plants; badly rusted, 9 plants. According to the leaf characters, by RYDBERG’S key the offspring would be classified as: R. macounii, 32 plants; R. fendleri, 5 plants; R. hypoleuca, 1 plant; R. fendleri, 1 plant.

Appendix II

An alphabetical list of the 16 Linnaean species in the section Cinnamomeae that are considered worthy of specific rank, together with six F1 hybrid species, follows. Seven ecotype species are placed under their related Linneons.

* Synonyms given by RYDBERG are not included in this list, except those he gave for R. macounii Greene, because culture experiments show that one collective species (R. woodsii) and an ecotype of the same species (R. macounii) are mingled in his designation of R. macounii.

The rose species given in the North American Flora by RYDBERG (34), also by the writer in Rhodora (13), in the sections Carolinae, Cinnamomeae, and Gymnocarpae, are grouped alphabetically under the Linneon in which each is now included. For further synonymy the North American Flora should be consulted.*
