9. I. heptaphylla Hiern, sp. n. 



Aji erect slender annual herb, branched from the base often in 

 a virgate manner, pallid, more or less appressedly hairy especially 

 on the leaflets beneath, 9 to 24 in. high or sometimes more ; 

 leaves imparipinnate, 2-4-jugate, usually 3-jugate, 1 to 3 in. 

 long ; lateral leaflets opposite or sub-opposite, sub-linear or 

 narrowly oval-oblong, rounded with a short apiculus at the apex, 

 rounded or somewhat narrowed at the very shortly petiolulate 

 base, entire, 5 to 1 in. long, ^ to \ in. broad ; terminal leaflet 

 similar, ranging up to I3 in. long, on a petiolule ranging up to 

 ^ in. ; stipules subulate, small ; stipels ; racemes axillary, 1 to 

 4 in. long, many-flowered ; common peduncle (below the first 

 flower) I to 2J in. ; flowers rose-purple, clustered along the upper 

 part of the rachis especially towards the apex, \ in. long ; pedicels 

 very short, shorter than or about equalling the lanceolate-subulate 

 deciduous bracteoles; calyx -^ in. long, clothed with appressed 

 whitish hairs, lobes subulate from an ovate or lanceolate base, 

 about as long as or a little longer than the tube ; corolla glabrous ; 

 standard obovate, \ in. long, exceeding the staminal slit tube ; 

 pods more or less spreading or declining, shortly and appressedly 

 hairy or sub-glabrate, 1 to If in. long, -^ in. broad, somewhat 

 compressed, slightly turning upwards near the apex, otherwise 

 straight ; seeds 12 to 16. 



This species resembles more or less /. po/rviflora Hayne, /. 

 goniodes Hochst., and /. costata Guill. & Perr. ; it differs from the 

 first by longer peduncles and from the others by fewer leaflets 

 and different calyx-lobes. It differs also in habit from I. Unearis 

 Guill. & Perr. which Baker in Oliv. PI. Trop. Afr. ii. p. 83 unites 

 with /. parviflora ; I. linearis DC. Prodr. ii. p. 228, from Sene- 

 gambia, not mentioned by Baker, is the same as /. aspera Perr.
