The generic disignation Lens (Tourn.) Linn, dates from 1735, and man- 
ifestly Lens phaseoloides, then entirely unknown to botanists, could not be 
its type. It so happens, however, that the combination Lens phaseoloides 
is the first one to be made in the genus after the establishment of binomial 
nomenclature. Lens (1735) was based on European species entirely differ- 
ent generically from the plant under discussion, and only our iules which 
state that binomial nomenclature shall commence with the publication of 
the Species Plantarum (1753), the genera to be interpreted by edition 5 
of the Genera Plantarum (1754) permit the illogical typification of the 
genus Lens by the species Lens phaseoloides. If there is any need of a 
generic list of nomina conservanda, the present case should certainly be 
included. The author is in sympathy with the idea of generic types, but 
in this case the proposition to consider Lens phaseoloides the type of the 
genus Lens impresses me as exceedingly illogical, for the species was entirely 
unknown to botanists, at least under this name, until about 20 years after 
the genus was originally proposed. 
CAESALPI N IOIDEAE 
CYNOMETRA Linnaeus 
CYNOMETRA BIJUGA Spanoghe in Linnaea 15 (1841) 201; Miq. FI. Ind. 
Bat. I 1 (1855) 78. 
McGregor 474, G. E. S. 44, 314- 
Frequently confused with Cynometra rami flora Linn., from which it is 
apparently specifically distinct; widely distributed in tropical Asia, extend- 
ing from India to Malaya and the Caroline Islands. 
TAMARINDUS Linnaeus 
TAMARINDUS INDICA Linn. Sp. PI. (1753) 34; Salford 383, pi. 66. 
G. E. S. 148, 484, locally known as camalindo. 
A native of tropical Africa, now cultivated in all tropical countries. 
I NTS I A Thouars 
INTSIA BIJUGA (Colebr.) 0. Ktze. Rev. Gen. PI. 1 (1891) 192; Safford 
297, pi. 54- 
G. E. S. 323, 445, locally known as ifil or ifit. 
Near the sea, eastern Africa through Malaya to Polynesia. 
BAUHINIA Linnaeus 
BAUHINIA MONANDRA Kurz in Journ. As. Soc. Beng. 42 s (1873) 73. 
G. E. S. 136, locally known as mariposa. 
Probably a native of tropical America, now found in most tropical 
countries in cultivation. This is probably the species mentioned by Safford 
(p. 196), without specific name. 
BAUHINIA TOMENTOSA Linn. Sp. PI. (1753) 375. 
G. E. S. 72, 381, locally known as mariosa or flor de mariposa. 
A native of India, now widely distributed in cultivation. This is prob- 
ably the second species mentioned by Safford (p. 197) as resembling the 
figure of Bauhinia blancoi in Blanco’s Flora de Filipinas. 
A third species is represented in the collection, from cultivated plants, 
but the material is not in condition for determination.
