maroon-coloured blotcli on tlie lip' of tlie normal form of the 

 species, wliicli is_ figured at t. 6013 of the Botanical Magazine. 

 In the allied species, D. fimbriatvm, Hook., and D. Bvyincrianum, 

 Reichb. f., the lip is normally fringed, but in D. Ilarvcyanuni, 

 Reichb. f., the petals as well as the lip are normally fringed, 

 though in other respects the species is very ilisiinct" from tlie 

 abnormal variety now under notice. A plant was exhibited at 

 the meeting- of the Royal Horticultuial Society held on 

 September 14th last, together with one of the normal form for

Botanical Magazine for October.— The plants figured are 



Pyrus yunnanensis, Franch. (t. 8G29) ; Gcntiana gracilipes, 

 Turrill (t. 8630); Promenaea microptera, Reichb. f. (t, 8G31); 



Streptocarpus denticulata, Turrill (t. 8632) and Clematis 

 unicata, Champion ex Benth. forma retusa^ Spragne {t. 8633). 



The Pyrus is a handsome tree belonging to the section Erio- 

 lohus, which Roemer considered a separate genus. F. TschonosJcii, 

 Maxim,, from Japan, and P. triloba tu, DC, from Syria, also 

 belong to this section. This group differs from the Aria group 

 in -vi'hich Pranchet placed P. yujumnensis by the styles being 

 united for their lower third, or more, and it is distinguished how 

 Mains by the grit-cells in the flesh of the fruit. The plant 

 figured was raised from seed sent to Coombe Wood, collected 

 by Mr. E. H. Wilson in the district of Charig-yang, Western 

 China, and was purchased from Messrs. Yciteh for the Kew 

 Collection in 1913, This species was originally discovered by 



Delavay in Yunnan. 



We are indebted to Mr. H. J. Elwes for the material of the 

 interesting Chinese gentian G. gracilipes, which was raised at 

 Colesborne from seed collected in Kansu ond received through the 

 late Mr. R. Woodward. This species belongs to the section apUra 

 of Kusnezow, and is nearly allied both to G, dahurica, Fisch., 

 and G. Fetisowii, Maxim. With the former it ngrees closely, 

 but differs in its longer pedicels and sj^athaceously divided calyx, 

 in which latter character it approaches G. Fetisowii.^ 



Promenaea microptera is an interesting little orchid, included 

 among those presented by the Dowager Lady Lawrence to Kcw. 

 It was described in 1881 by Eeichenbach, but its exact habitat 

 is uncertain. The nearest ally to the species is P. ^aiithinu 

 Lindl., from Brazil, but the genus also occurs m Guiana and 

 Colombia. Promendea was founded as a genus by Lmdley, and 

 after having been merged in Zpopetalum by Roichenbach, wan 



restored later by him to generic rank. ^ ^, ., ,. . ., 



The Streptocarpus belongs to the section Umfohatae, ot the 

 genus of which some 15 species are known from South Atnrn, 

 S. denticuhfa is a native of tlie Transvaal, and the seed was

glabrous leaves and short-tubeJ flowers. The rose-purple flowers 



are very distinctive. . „ ,, , 



The striking form of Clcynatis uncvnata differs from the type
