"ium really consists of five compound and 

 sonfluent stamens superposed to the sepals. 

 Dr. Dickson is of opinion that the only 

 [issential difference between Mentzelia and 

 ts allies, on the one hand, and Loasa and 

 Its allies on the other, is, that in the for- 

 ner the evolution of staminal lobes is cen- 

 ■ripetal, in the latter centrifugal : both 

 eries of genera agreeing in. having five 

 iompound stamens superposed to the sepals. 

 This difference in staminal evolution does 



I lot appear to Dr. Dickson sufficient to 

 ustify the breaking up of the old order 

 joasacese, as has been done by Payer in his 

 " Lecons sur les Fam. Nat. des Plantes." 

 n the Rosacese, where Payer had recognised 

 , similarity in staminal evolutions to the 

 >Ientzelia), Dr. Dickson believes that those 

 ,ndroecia the development of which has been 

 xamined may be arranged under two types: 

 -1. Aremonia type ; stamens superposed 

 o the sepals, with or without a true corolla. 

 Examples— ^remo9im, Agrimonia, San- 

 misorha, Poterium. In Aremonia, and 

 )!anguisorha the stamens ?re simple ; in 

 igrimonia they are compound and distinct; 

 nd in Poterium, compound and confluent. 



I, Alchemilla type ; stamens alternate with 

 he sepals ; no true corolla. Examples : — 

 Ucliemilla, Ruhus, Rosa, Geum, Fragaria, 

 ic. In Alchemilla the stamens are simple, 

 n Ruhus and the others the stamens are 

 ;ompound and ccJnfluent, with their ter- 

 minal lobes developed as petaloidstaminodes 

 the petals ordinarily so-called) analogous 

 0 the petaloid staminodes forming the inner 

 :orolla of Bartonia an ally of Mentzelia. 



II. Report on the Cinchona Plantation 

 jt Darjeeling in February 1865, by Dr. 

 I'homas Anderson. 



I . III. Abstract of a Report on the Pitayo 

 !)inchonas by Mr. Robert Cross. 

 D. D. Moore, Glasnevin, sent living 



lants of Neotinea intacta from Galway. 

 |le stated that he had seen about forty 



ilants in the station, but only one of them 

 , Iras in flower. They grew on a dry bank 



lose to limestone gravel. Mr. Sadler stated 



h.at Dr. F. B. White had recently gathered 



the following rare mosses near Perth :— 

 Grimmia orhicularis, rocks on Kinnoul 

 Hill ; G. Schultzii, Dunsinane Hill ; O. 

 leiLcophoea, Callerfountain Plill ; G. iricho- 

 phylla do. ; Hypnum aMeiinutn, do. ; H. 

 rugosum, do. Dr. Dickson exhibited 

 growing plants of Pinguicula vulgaris, 

 from various Scotch localities. The plants 

 showed some marked diff'erences in their 

 flowers and leaves, and seemed to indicate 

 at all events distinct varieties. Mr. M'Nab 

 placed on the table growing plants of 

 hybrids produced between Primula, vulgaris 

 and P. veris, and between P. vulga.ris and 

 P. elatior ; also a plant of Athyrium Filix- 

 fcemina var. Victoria, from Buchanan 

 House. Mr. Gorrie exhibited specimens 

 of a large blue-flowered Anem.one, found 

 naturalised at CuUen House : also a plant 

 of Myosotidium nohile from Chatham 

 Island. The following gentlemen were 

 elected members of the society : — 1. As a 

 Resident Fellow — Ramsay H. Traquair, 

 M.D., 30, Clarence Street. 2. As a Foreign 

 Member — M. Dominique Clos, M.D., Pro- 

 fessor of the Faculty of Science, and 

 Director of the Botanic Garden, Toulouse, 

 Richmond and North Riding Naturalists' 

 Field Club. — Monthly meeting, Tuesday 

 June 13th, 1865. The president E. Wood, 

 Esq. , F. G; S. , in the chair. There was a large 

 attendance of • members together with a 

 number of ladies. Two new members were 

 elected. The president exhibited specimens 

 of the organs of hearing in the diff'erent 

 species of fish, called ear-bones ; also a 

 quantity of fossils and some specimens of 

 landscape marble and of iron pyrites im- 

 pregnated with gold. The secretary exhi- 

 bited specimens of the Golden Eye, Anas 

 cla.ngula, and Scoter Anas nigra, recently 

 shot at the Tees-mouth, — also, a box of 

 Lepidopterous insects, collected during the 

 present month. The president stated that 

 he hoped by the next monthly meeting to 

 be able to lay before them some fossil 

 human remains, from the Shetland Isles ; 

 where he and several other geological 

 friends intended exploring, by the kind
