point, continuous with the stem and shortly and trifaviously or irregularly 

 decurreut. Flowers in heads or spikes, on axillary simple peduncles. 



This small series connects the J/atte with several others, and I had much doubt whether 

 it would be most convenient to unite the species with A^atce as in my former papers, or with 

 Pungentes, with which they more generally agree, or distribute them into several of the 

 series, placing A. incurva and A. tngonopkijlla in the A/at(S, A, continua \\\ the Puiigentes, 

 A. Peace \]ii\iG Calamifomm; nuA J, Upl^ra in the Jul 7ft or a, hni on the whole it ap- 

 peared to me that these large series remain better defined, if the CouliuucB are collected into 

 a small intermediate group. 



6. A, incurva, Benth. in Hook. LoncLJourn. i. 325. A rigid shrub 

 of U to 2 ft., glabrous or slightly scabrous. Phyllodia continuous with 

 the stem and shortly and trifiiriously decurreut, linear or linear-lanceolate, 

 incurved or recurved, mostly 1^ to 2 in. lon^, rigid and tapering mto a puu- 

 gent point, 1-nerved, without marginal glands. Stipules minute or shortly 

 setaceous. Flower-heads globular, mostly solitaiy and almost sessile, con- 

 taining 4 to 8 flowers, mostly 4-merous. Calyx very sliort. Petals membra- 

 nous, not striate, the buds very angular. Pqd unknown,— Meissn. m rl.
