reversed by a half turn of either the germen or pedicle, a 

 secondary process consequent upon expansion. In the pre- 

 sent genus no such process takes place, and the corolla re- 

 tains its connatural position till it decays. 



It was in this genus that the middle petal of the lower 

 lip had been mistaken by Swartz for the label of the corolla, 

 and the mistake rectified by Mr. Brown, who has shown the 

 helmet-shaped petal at the back of the flower to be the 

 true label ; a part always determinable by its position in 

 relation to the germen, being the middle petal of the three 

 inner ones, all opposite to the three valves of the germen, 

 while the three out^r ones are opposite to the three in- 

 tervening prominent riblike sutures. The label is usually 

 different from the other petals, either in consistence, form, 

 or colour ; sometimes in all three ways. 



We are convinced that the species before us is the same 

 with Satyrium erectum of Thunberg*s Flora Capensis, though 

 possibly different from the plant intended by Swartz under 

 that name. 



The drawing of this rare and handsome-flowered vege- 

 table was taken in the greenhouse of Mr. Lee at Hammer- 

 smith ; where it had been imported from the Cape of Good 

 Hope, the native place of the species. 



We doubt much whether Satyrium parviflorum of 

 Swartz (Orchis bicomis. Jacg. hort. Schcmb. 2. 26. i. 179) 

 is distinct from Satyrium cucullatum (fol. 416) of this 

 work, which is certainly Orchis bicomis of the first edition 

 of Hortus Kewensis, and Satyrium cucullatum. of the se- 

 cond. We believe several of the recorded species of this 

 genos are mere iterations. 



Dispersed in some of the earlier volumes of " The Jour- 

 nal of Science and the Arts** will be found sixteen coloured 

 representations taken from the living plants of as many 

 rare and curious species of Orchidece belon^ng to the Cape 

 of Good Hope, all of them executed with great accuracy. 

 The original drawings are in Mr. Brown*s library ; but the 

 name of the meritorious Datch artist, who drew them for 

 Mr. Masson, the then King*s collector, is unknown. (See 

 last page of fol. 700.).
