HA RD WICKE'S SCIENCE- G OS SIP. 



W. H. J. (Uppingham). — The articles named will probably 

 be continued during the summer months. Names of the species 

 inclosed were as follows : — a. Scirjms carinatus (Sm.) ; by 

 Hooker made a subspecies of S. lacustris ; we believe it to be 

 distinct, c. Panicum Crus-galli (Linn.) d. We think, this is 

 a melilot, one not seen before, but will tell you next month. 

 e. Setaria viridis (Beauv.) f. Ononis arz'eusis, (Linn.) g. 

 Eleocharis uniglumis (Link), h. Glyceria aqitatica (Sm.) b, 

 A pretty viviparous form of Cynosurus cristatus (L.) ; a valuable 

 specimen. Note. — Your observation, amongst botanical notes. 

 We wish all our correspondents would send us good specimens ; 

 yours are excellent. 



W. K. (Leeds). — The seeds you so kindly send are niger 

 seeds, so called in commerce ; but they are obtained from 

 Gaizotia olcifera, cultivated in India chiefly for the sake of a 

 bland oil, not unlike sesamum oil, which burns in small hand- 

 lamps, without smoking. This product is known as ram-til oil in 

 Mysore. We are puzzled by your other question. Do you mean 

 the olden lentil (Ervum Lens, L.) ? Could you let me see a small 

 sample? 



W. F. (Shaw Hall, Botanical Society, Greenfield.) — We believe 

 the specimens are Erigeron bonariensis and Escallonia rubra. 



H. B. (Prestbury). — The ferns are Adiantum caudatum, 

 Chcilanthes fragrans, and Nothoclileena vellea. 



D. R. B. (Picton, Bunbury, West Australia). — Only one 

 specimen we suppose to be named came to hand. It was a 

 pretty mounted flower, a Thysanotus, probably T. proliferus. 



B. Sharpe. — The example sent, was not in a good state for 

 examination. Try Dysoxylon. 



W. H. J. (Uppingham). — The plant labelled d, is Medkago 

 falcata. 



R. A. B. (Glasgow). — Pardon our overlooking the specimens 

 so long. They are as follows: — No. i. Equisetum tatmatcia; 

 No. 2. Hieracium vulgatum ; No. 3. Briza media ; No. '4. 

 Poa alpina ; No. 5. A viviparous specimen, probably Poa sj>.
