every one of the fifteen Indo-Malavan species described by him has two stipules at the 

 point of its junction with the stem, at the same level, and therefore " opposite. " As 

 the stipules vary much in size, so does their attachment cov.r a larger or smaller part 

 of the stem. The large stipules encircle the stem, leaving, when they fall, bold annular 

 cicatrices. The smaller stipules have but a small lino of attachment; their cicatrices 

 are correspondingly small, and of course do not meet to form a ring. Sometimes the 

 attachment of one of a pair of stipules extends partly into the axil of its leaf, and it 

 thus becomes u intra-petiolar , " while the twin stipule originates from the stem, either in 

 the normal lateral situation or a little further from the loaf than usual. Hut in all tho 

 principle of attachment is the same. Moreover, even were Trend's stipular chai cter 



based on fact, it is a difficult one to work in the Herbarium; for the stipules of the 

 genus are so deciduous that they are rarely found in dried specimens. I propose there- 

 fore to abandon Trecul's division into Jaca and Pseudo-Jaca, and to arrange tho species 

 of British India into two groups, according as the apices of the anthocarps on the female 

 inflorescence are free at the apex, or are completely united. The former arrangement 

 gives a spiny or tuberculate, and the latter a smooth, syncarpium. 



I ought to explain that, by British India, I understand the Peninsula of Hindustan, 



Ceylon, Burmah and the Malayan Peninsula ; with the islands of Penang and Singapore. 

 and the Nicobar and Andaman groups.
