The term intercalary is proposed for such. The origin of these 

 inflorescences is indicated, and their further evolution mto j^studo- 

 terminal inflorescences shown. 



A discussion ensued in which the following engaged : Dr. A. B. 

 Eendle, Mr. F. N. AVilliams, Dr. D. H. Scott, Mr. W. C. 

 Worsdell, Prof. F. AV. Oliver, and Dr. 0. 8tapf, the author 

 briefly replying. 



Mr. C. E. SALMO]!ir, T.L.S., then read a note on " Hypericum 

 Desetangsii, Lamotte, in Britain," illustrating his remarks by a 

 series ot specimens of that species and its nearest allies, together 

 with a lantern-slide. 



He stated that in 1893 the late Mr. T.Hilton, of Brighton, 

 collected what he considered to be JI. chthium, Leers, in the 

 vicinity of Lewes. Some yeai.'s after, the specimen came into 

 the author's hands and was seen not to be the usual plant so 

 named. 



Various causes prevented him from visiting the locality at the 

 proper season until the pi-esent year, \\hen good examples were 

 examined on the spot and afterwards inore minutely at home. 

 A drawing was made of the plant when alive, and a lantern-slide 

 made from the plate Avhich appeared in the 'Journal of Botany ' 

 for jSToveiuber 1913, was now shown with Mr. Britten's kind 

 permission. 



It appears that the Lewes plant must be placed under the 

 species published by Lamotte (in Bull. Soc. Bot. Pr. xxi. 121) in 

 187-1, as H. Desetangsii, and further elaborated, in the same 

 journal, by Bonnet in 1878. 



It may be roughly distinguished from H. perforatum — of which 

 it has the goklen-yellow flowers — by its 4-angled stem ; from 

 H. tetraptenim by the colour and size of its flowers, and from 

 H, quadrangulum [H. duhium) by its dotted leaves and narrower 

 sepals. These are main distinctions ; finer ones exist. 



In the upper leaves of //. Desetavgsii the main veins only are 

 translucent and the whole leaf is pellucidly-punctate ; in H. qiiad- 

 rangultim the veins anastomose and all are translucent ; pellucid 

 dots are somewhat rare. When they do occur the specimen is 

 referable to the var. punctatur,%, Schinz, but no examples named 

 with authority have been seen. 



Bonnet divided Hypericum Desetangsii into o. genuinum and 

 (i. imjH'rforatiim, but, so far, the latter has not been seen from any 

 British localities. The genuinum form grows, as mentioned, near 

 Lewes, and dried specimens from Eichmond, Yorkshire, collected 

 by B. B. Bowman, and from near Caton, W. Lancashire, gathered 

 by J. A. Wheldon, have been seen. Dr. Thelbnig reported it 

 from England in 1912, and it was elicited that the example seen 

 by him was found by Prof. Dr. H. Schinz in 1903 growing 

 spontaneousljr in the garden of the Eev. Mr. Hooper, at Cam- 

 borne, {Cornwall. Abroad, it has been found in eastern, northern,
