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,

R. Babingtonii, Bell Salt. in Ann. Nat. Hist. xv. 307. 
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 setz of the same form. Leaves 
dark green with a few scattered hairs above, paler green with 
rather more numerous short hairs beneath, ternate or oceasion- 
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 sete. Floral leaves very large; lower ones ternate ; 
upper ones simple, ovate-acuminate, lobed. Sepals yellowish,
