Mr. Baker quotes Persoon as the author of his subgenus Stizolobium. But to 

 Persoon Stizolobium was a genus including all Baker's subgenera. So he quotes 

 •Roxburgh as the author of the subgenus Carpopogon ; the same objection applies 

 here. The citation of Loureiro as the authority for Citta is however particularly 

 unhappy, for it is in the highest degree probable, from a study of Loureiro's des- 

 cription and from the knowledge we now possess of its distribution and characters, 

 that Mucuna imbricata, which is the basis of Amphiptera, is the species described by 

 Loureiro as Citta nigricans ; specimens of what is undoubtedly M. imbricata, noted 

 as having white flowers with purple spots, have recently been sent from the 

 Shan Hills to Herb. Calcutta ; there is, therefore, not one character now left which 

 militates against the identification of Loureiro's plant with M. imbricata. In any 

 case since Loureiro's plant had 3-seeded pods, it cannot possibly have been either 

 M. monosperma or M. atropurpurea, which constitute the Citta of the F. B. I. 



Subgen. I. Zoophthalmum. Perennial climbers ; seeds large flat, 

 with a large hilum extending round the greater portion of their circum- 

 ference. 



§. Citta. Pods plaited across their faces. 



1. Mucuna imbricata DC. 



Add to localities of F. B. I. :— North-West Himalaya ; Vicary ! A. 

 0. Hume ! King ! Manipur ; Watt ! Burma ; Pegu, Brandis ! Shan 

 Hills ; " flowers white and purple," King's Collectors ! Andamans ; 

 common, King's Collectors ! 



Bracteoles at base of calyx in bud similar to bracts but many times smaller and 

 more deciduous. 



Nearest to this is perhaps Mucuna Junghuhniana [Stizolobium Junghuhnianum 

 Kuntze (Rev. Gen. PI. i. 208) ] from Java, which differs in being strigosely hirsute 

 and in having pods with plaits extending partly across the wings. The plant referred 

 to by Kurz (Joum. As. Soc. Beng. xlv. pt. 2, 246) as a new species near If. atropur- 

 purea is M. imbricata ; Mr. Kurz has himself made the reduction in Herb. Calcutta. 



2. Mucuna monosperma DC. 



Add to localities of F. B. I. : — Andamans ; very common every- 

 where in the interior jungle. Distrib. Sumatra. 



Bracts at base of pedicels small triangular, much smaller and much more early 

 deciduous than the linear bracteoles exceeding the bud. One of the Calcutta 

 examples of Wall. Cat. 5623 is Mucuna imbricata, the other is a mixture of M. 

 imbricata and M. macrocarpa ; there is no M. monosperma whatever on either sheet. 

 Wall. Cat. 5622 must be equally confused ; Mr. Baker finds that the plant represent- 

 ed is M. monosperma ; at Calcutta on the other hand 5622 is M. gigantea. 



3. Mucuna atropurpurea DC. Zoophthalmum atropurpureum 

 Prain MSS. 



Delete from localities of F. B. I. : — Malacca. 



The Malacca plant referred to M. atropurpurea in the F. B. I. belongs to a 

 distinct species and proves to be M. biplicata Teysm. & Binnend. 



3a. Muccna biplicata Teysm. Sf Binnend. in Cat. Hort. Bog. 261 ;
