very few extremely short aciculi may also be found : some of these 

 specimens have almost glabrous barren shoots. We thus see an 

 approach to the species included in the next section. 



Obs. 2. Mr. Lees has favoured me with fine specimens of his 

 R. amplificatus. It presents a different appearance from R. ma- 

 crophyllus, but I fear that it must be considered as a variety of 

 that species. Its chief difference is found in the panicle, which 

 is very much longer, and has rather long axillary branches be- 

 low, which form a very acute angle with the rachis when the plant 

 is in flower, but afterwards appear to become much more spread- 

 ing. The prickles on the panicle are usually much stronger, and 

 the dense pubescence is beautifully tinged with yellow. One of 

 the specimens has an enormous panicle, each lower branch of 

 which has the same structure as that which is usual to the whole 

 inflorescence.

A very large stout plant of peculiar appearance. Stem green- 

 ish purple, rounded and sulcate, with very short thick-based 

 prickles and numerous aciculi and setae of the same form. Leaves 

 dark green with a few scattered hairs above, paler green with 

 rather more numerous short hairs beneath, ternate or occasion- 

 ally quinate by the subdivision of the lateral leaflets, in which 

 case the lower leaflets are stalked. Petioles armed like the stem. 

 Stipules linear, membranaceous, hairy and sparingly glandulose. 

 Panicle more than three feet long, with large branches forming 

 secondary panicles. Rachis, branches, peduncles and petioles 

 with numerous long slender straight declining yellow prickles 

 with broad purple bases, numerous hairs and small aciculi and 

 unequal setse. Floral leaves very large ; lower ones ternate ; 

 upper ones simple, ovate-acuminate, lobed. Sepals yellowish,
