is quite distinct from R. antennulifera. But this second species rather 
weakens than strengthens Eminia as a genus, and it is proposed 
to treat it as a section of Rhynchosia here, 
Rhynchosia (§ Eminia) Holubii , HemsI. nov, spec. : foliis per 
anthesin persistentibus, foliolis oblongis sinuatis ; racemis folia vix 
superantibus ; calyce quam corolla dimidio breviore, laciniis 3 inferior!- 
bus saepius 2-3 glandulosis ; stylo per totam longitudinem glabro. 
Herba , ut videtur, perennis, caulibus . . . . ? Folia graciliter 
petiolata, pinnatim trifoliolata, coriacea, strigillosa, cum petiolo 3-5 
poll, longa ; foliola breviter petiolulata, oblonga vel anguste ovato- 
oblonga, 2-3 poll, longa, lateralia paullo minora, sinuata vel obscure 
paucicrenata, utrinque obtusissima, simul apice minute apiculata, 
supra parce strigillosa, scabrida, venis elevatis grosse reticulatis, 
subtus argentea, dense strigillosa, venis primariis lateralibus utrinque 
circiter 5, stipellis obsoletis. Flores circiter 9 lineas longi, fasciculato- 
racemosi, brevissime pedicellati, racemis axillaribus folia subaequanti- 
bus calyceque argenteis strigilloso-hirsutis ; calyx sub-bilabiatus, alte 
inequaliter 4-fidus (i. e. laciniis 2 superioribus fere ad apicem con- 
natis), lacinia inferiore saepius apice 3-glandulosa, laciniis lateralibus 
saepius 2 -glandulosis, labio superiore saepius eglanduloso ; petala 
fere aequilonga, unguiculata, glabra, vexillo lato le viter emarginato ; 
stamina glabra ; ovarium subsessile, apice praesertim longissime 
setulosum, stylo longissimo breviter exserto glabro. Legumen 
ignotum. 
Apart from the great difference in foliage, and apparently in habit, 
this species differs in the relative length of corolla and calyx, and 
especially in the two upper calyx-lobes being connate nearly to 
the apex and eglandular, and in the three lower being furnished with 
two or three glands at the apex.

ON THE PRESENCE OF A DIASTATIC FERMENT IN 
GREEN LEAVES. — I have been led to re-investigate this subject 
in consequence of the statement made by Wortmann 1 in a paper 
recently published, that green leaves contain no diastase or only such a 
minute quantity that it cannot be of any serious importance in the 
transformation of starch into sugar which takes place so actively in 
those organs. In contradiction of the results obtained by Baranetzky 2
