This differs fi-om the type in the leaves, which more r-esemble those of L. Retosa ; 

 and in the bracts, which are quite unlike those of true L. hirsiitissima. The in- 

 florescence, calyx and corolla are quite like those of the true plant, but the corolla 

 is reported in the Maymyo gathering to be white j that of true L. hirsiitissima ia 

 said by Prazer to be purple. It is not impossible that this may ultimately prove to 

 be specifically distinct. 



What appears to be a third variety of this species is reported (but 

 in fruit only) by our native collectors from the Ruby Mines District. 

 The bracts in this plant are as in var. typica, but the tomentum is as 

 in L. setosa.

Though less common in Indo-China than the plant described by Mr. Clarke 

 as L. peguensis, this is widely spi'ead throughout Upper Burma ; it does not appear 

 to extend to Tenasserim where its place is taken by L. pegncnsis. This forms part 

 of Kurz's Argyreia capitata — which is thus co-extensive with Choisy's, but it is not 

 Miquel's Lettsomia capitata which is founded on a Java plant collected by Horsfield 

 that, so far as the Calcutta sjiecimen goes, is undoubtedly L. pegueiisis Clarke. 



There is no doubt, from the description given by its author, that this is Convol- 

 vulus capitatus Vahl. Dr. Wallich, himself one of the editors of the fii-st edition of 

 Roxburgh's Flora Indica, admits that this, though the Lettsomia strigosa of that 

 work, is not the Lettsomia strigosa of the Hortus Boigalensis, which was issued (Cat. 

 n. 1404/1) as Convolvulus barhiger Wall. ; unfortunately Wallich associated -vWth this a 

 different plant (or rather a mixture of two) from Burma {Cat. n. 1404/2). One 

 of these Choisy has made the type of his Argyreia harhigera {Lettsomia barhigcra 

 Clarke) the other has dropped out of notice as completely as has the plant that 

 Wallich really intended by Convolvulus barhiger.
