 1922. — A large party of members travelled by charabanc to 

 Hope Valley and Hermitage to study the flowers of the district. 

 Near the Hope Valley Reservoir a halt was made at a piece of 

 natural scrub not yet cleared. The soil, of a very sandy 

 nature, just suited to the native flowers which were 

 found in wild profusion. Among the orchids seen 

 were many specimens of spider orchids, Caladenia Pater- 

 sonii, C. reticulata, C. dilatata, C. latifolia, somew^hat rare, C. 

 deformis. Several wattles were in bloom, including A. myrti- 

 folia (scrub wattle), A. spinescens (spiny wattle), A. pycnantha

 pard), Diuris palustris (swamp), D. longifolia, D. Menziesii 

 (rabbit's ears), Thelymitra antennifera, T. luteocilium, and 

 Acianthus exsertus (the mosquito orchid), which has a single 

 leaf, green above and red below. The "blue squill" 

 (Chamaescilla corymbosa) made patches look a garden of blue 

 flowers. "Guinea flowers" (Hibbertias) abounded in this 

 sandy soil, H. virgata, H. sericea, and H. stricta were noted. 

 The pretty "cats' claws" (Grevillea lavandulacea) was plen-

 gona). Two Hakeas were flowering well, the "wrinkled" 

 (H. rugosa) and the "furze" (H. ulicina). Amongst the 

 white flowers were some Pimeleas. Several species of sundews 

 were found, including one with pink flowers (Drosera glan- 

 duligera). The "banded blue lily" (Caesia vittata) was
