LINNEAN SOCIETY OF LONDON. II 



The following exhibitions were shown by permission of the 

 Director, Eoyal Botanic Gardens, Kew : — 



(1) Mr. ^y. BoTTiNG Hemslet, F.R.S., F.L.S., sent for exhibi- 

 tion a second specimen of Platanthera chlorantJia with three spurs, 

 Avhicli was described in his absence by Mr. C. H. Wright, A.L.S. 

 The plant now shown came from the Rev. E. A. Woodruffe- 

 Peacock, F.L.S., to whom it had been sent by Miss Susan Allett, 

 of Bath, and exhibited a spike, each flower of which had the three 

 petals spurred, a case of true peloria, whereas the specimen shown 

 on 17th January, 1907, had the three sepals spurred, a case of 

 false peloria. 



In consequence of the publication of the latter specimen in the 

 Society's Journal (Botany, vol. xxxviii. (1907) p. 3), Cav. Sommier 

 has drawn attention to the occurrence of true and false peloria in 

 P. bifolia in the neighbourhood of Florence. 



Dr. A. B. Eendle offered a few remarks on this exhibition. 



(2) Mr. T. A. Sprague, F.L.S,, showed female flowers and 

 fruits of Sterculia Ale.vandri, Harv., an extremely rare tree from 

 Uitenhage, the only locality known for it, where it was first found 

 in January 1848 by Dr. R. C. Alexander, F.L.S. (afterwards 

 Prior). The specimens shown had been collected by Dr. S. Schcin- 

 land, P.L.S., who reported that the seeds were of pleasant taste 

 resembling a chestnut, and were greedily sought after and 

 devoured bj' the baboons. 



Discussion was carried on by Mr. A. P. Young, Mr. J. R. 

 Drummond, and Mr. E. M. Holmes, Mr. Sprague replying. 



(3) Mr. C. H, Wright, A.L.S., showed specimens of (a)Sj>hm'o- 

 tliylax ahjiformis, Bisch., a rare South-African Podosteraaceous 

 plant, and spoke of the outward resemblances of some plants of 

 this family to certain cryptogams, showing side by side examples 

 of Hydrostachys imbricata, A. Juss., and IT. nana, Engl., as 

 resembling the alga Caulerpa aqjressoides, and Tristiclia Jiypnoides, 

 Spreng., with the form of a moss ; also (b) Archangiopteris Henryi, 

 Christ & Gilsenh., a Chinese genus of Marattiaceae, of which a 

 better supply of material had been recently obtained. 



The discussion on these exhibitions was engaged in by Dr. A. B. 

 Rendle, Mr. J. C. Shenstone, and Dr. D. H. Scott, the latter 

 expressing his concurrence in the view that the genus Archangio- 

 pteris was very nearly allied to the older genus Angiopteris.
