June 7 (Sunday). Worked on Juneau material, and species of Poa. The species collected at Owl Hollow and below Kerby-Smith junction is P. cuspidata (P. brachyphylla) with culms more sparse than in other material examined. Poa sylvaris (especially well represented in Washington region) has several branches in a head in the penicill and they are usually reflexed. P. ant- unnalis is much similar but usually with 2 branches in a whorl, and these not reflexed; the spikelets a little larger. P. debilis & erect, collected by me at Naples Crest, the lemmas are smooth. P. saltunensis is the commoner species in woods (collected at Joffe in 1934) and has rather stiff branches and much in narrower former leaves than P. alaska. P. palestris (P. triflora) appears to be much less common in meadows and has very small flowers. Arthroca tus (Bacmutens) except for the absence of basal hair tufts so much like Poa. Southern form of Claytonia virginica has several leaves and seed averaging 1.6 mm., just as in northern. June 8 (Monday). Went to Mrs. Nat. History to find out about Stephen Calverley. He came from Brooklyn; had a melanic Papilio (P. Calverleyi) named for him, and identified with H.W. Edwards and Wiedemeyer. June 9 (Tuesday). To Jossy Pond, Monerville, with Miss Rusk, Mr. Durkin, and Mrs. Putz. The season early for most plants, but found two specimens of Arthusa. Other things of interest: Nymphaea odorata var. minor, Vac- Cicium Oxyceros, Nymphaeathus advena, Eriophorum, Ceres atlantica, C. Howei, C. Walteri, Rynchospora fusca.
