518 MR. G. BENTHAM—REVISION OF THE GENUS CASSIA. 
120. C. aENIGERA, Wall.! Cat. Herb. Ind. n. 5307. Foliola 10-20-juga, anguste oblonga 
(2-pollicaria), pubescenti-villosa. Stipule amplæ, reniformes. Flores ....? Legumen 
eylindricum, 1-2-pedale, leeve, glabrum. 
Hab. Tropical Asia: Taong Dong mountain in Burmah. 
Undique molliter pubescens. Foliola obliqua, parum inzequilatera, brevissime petiolulata, petiolo com- 
muni 8-10-pollicari. Stipule membranacex, lateraliter affixæ (semicordato-reniformes), 8-10 lin. longæ, 
apice breviter aristate. : 
The species is as yet very doubtful. The specimens are very indifferent, in leaf only, and resemble on 
the one hand C. megalantha in Fistula, on the other C. Timorensis in Chamesenna. The fruit is detached, 
but labelled by Dr. Wallich in the fruit-collection of the Linnean Society as that of C. renigera from 
Taong Dong, and is quite that of C. Fistula. 
Subgenus II. SENNA. 
Genus Senna, Roxb. EN 
Frutices, herbze v. rarius arbores, habitu vario. Glandulæ petiolares dum adsint plus 
minus elevatæ, conicæ subglobosæ oblongæ v. tenues stipitatæque. Racemi 2- multiflori 
ut plurimum ex axillis superioribus ramulorum hornotinorum, rarius ad nodos defoliatos 
ramorum vetustiorum oriundi, superiores v. fere omnes nonnunquam paniculam termi- 
nalem corymbosam v. pyramidatam efficientes, summi tamen decrescentes nec in race- 
mum terminalem simplicem abeuntes. Sepala obtusa vel rarius exteriora presertim 
acuta. Stamina perfecta nunc 7 v.rarius 6, 3 summis et interdum infimo ad stami- 
nodia reductis, nunc (in sect. Psilorhegmate) 10, æqualia v. sæpius inæqualia, 3 inferiora 
filamentis sepius longioribus antherisque majoribus; filamenta omnia sepius anthera 
breviora nune brevissima; antherz crasse, oblongo-lineares, subquadrate, apice nune 
truncatæ poro duplici dehiscentes, nunc sæpius plus minus rostratæ rostro 1-2-poroso, basi 
obtusæ v. breviter acuteque bilobæ; staminodia 3 summa filamentis brevibus antheris 
seepius in laminam simplicem v. bilobam dilatatis, infimum dum adsit staminibus per- 
fectis magis conforme nisi parvum anthera cassa. Legumen forma magnopere diversa, 
ad suturam interiorem v. utramque dehiscens valvulis tamen haud elasticis, v. rarius in- 
dehiscens, exocarpio tunc haud lignoso demum irregulariter resoluto. Semina transversa 
obliqua v. longitudinalia, funiculis filiformibus. 
In several species, especially amongst the Bacillares, Floride, and other larger Chamefistule and Cha- 
mesenne, the petals usually enlarge considerably after the flower first expands, but, in some mln 
appear to remain short and imperfectly coloured in some of the flowers, whilst they become fully developed 
in others of the same raceme, or in other specimens of the same species. 
Sectio 2. CHAMÆFISTULA. 
Frutiees, rarius arbores v. (in Brachycarpis) herbe. Folia interglandulosa, rarius 
eglandulosa. Stamina perfecta 7, staminodia 3. Legumen teres, turgidum v. leviter 
compressum, ad suturam superiorem rarius ad utramque suturam dehiscens, v. (in Bicap- 
sularibus) indehiscens. Semina transversa, septulis parallele compressa, sepe in | 
gemina, septo verticali plus minus perfecto interposito. 
This section is readily distinguished from Oncolobium by the want of the basal petiolar gland, from 
Prososperma by the direction of the seeds, which may be observed long before the pod is ripe. But,
