should add, has been compared by my friend Dr. Schaum with 

 examples of that species in the Museum at Berlin), were cap- 

 tured by Senhor Moniz, in the houses and shops of Funchal, 

 during the summer of 1858; and I may state that I have my- 

 self taken it in similar positions in the Canary Islands,

 Structure of the Seed in the Family of the Rhanmacese. By

2. NOTOPH^ENA. 



I propose this genus for a separate group, with flowers di- 

 stinguished by the same peculiarity as those of Colletia the 

 total absence of petals, but differing from the latter genus in 

 its habit, its copious foliage, and in the form of its disk, which 

 resembles that of Discaria. It is also characterized by the 

 peculiar feature before alluded to the union of the base of the 

 opposite stipules, which gives an appearance of an articulation 

 at every node, a peculiarity often seen also in the middle of 

 the spines when they are foliiferous. The type of the genus is 

 the Colletia serratifolia of Ventenat, from Chile ; the other species 

 are mostly from the southern parts of the same country, and one 

 is from New Zealand : hence the generic name, from voro-?, auster ; 

 fyaivojjLai, appareo. They sometimes form very leafy shrubs, 

 at other times low decumbent bushes, bare of spines. Here we 

 generally see a spineless branchlet issuing from below each spine, 

 and bearing both leaves and flowers, which quite confirms the 

 supposition that the scaly tubercle seen in Colletia and other 

 genera is only a very abbreviated or suppressed branchlet. 



NOTOPH^ENA, gen. nov. ; Calyx urceolato-campanulatus, usque 

 ad medium 4-5-fidus, laciniis reflexis, intus carina prominula 

 calloque apicali notatis, sestivatione valvatis, imo demum cir- 

 cumscissus. Petala nulla. Stamina 4-5, tubo calycino inter 

 laciuias inserta ; filamenta filiformia, laciniis breviora, erecta ; 

 anthera ovatse, 2-lobse, 2-loculares, loculis rima longitudinali 

 antice hiantibus. Discus pateriformis, hypogynus, imo tubi 

 adnatus, margine brevi, libero, crenato. Ovarium superum, 

 globosum, ssepe pilosum, 3-sulcatum, 3-loculare; ovula in 

 loculis solitaria, erecta. Stylus brevis, calycis tubum sequans. 

 Stigma obtusum, breviter 3-lobum. Fructus siccus, sub- 

 globosus, cupula calycina discoque suffultus et aduatus, in 

 coccos 3 resiliens ; istis seminibusque ut in Colletia.
