90 BOTANY OF SOCOTRA. 



be an Aden species, probably A. eburnea, Willd. But I cannot find in Kew 

 Herbarium any Aden plant like it, and it is very different from A. eburnea as 

 there represented. 



The following is a description so far as is possible : — 



Suffrutex glaber ramis albidis striatis ; spinis stipularibus nitentibus albis apice nigris divaric- 

 atis rectis foliis sequilongis v. longioribus ; foliis bipinnatis, pinnis 1-jugis rhacbi sub 

 strumis villosa ; foliolis 2-3-jugis \ poll, longis oblongis obtusis crassis glabris. Cast, 

 ignot. 



Socotra. On the plains near Galonsir. B.C.S. n. 96. 



Order XXVII. CRASSULACE^E. 



A considerable family, chiefly found in temperate and cooler regions of 

 Europe, west Asia, south Africa, and North America. Of the two Socotran 

 genera, one has a wide distribution over the globe, the other has a maximum in 

 south Africa, but extends into Asia, and even to Brazil.

2. KALANCHOE. 



Kalanchoe, Adans. Fam. ii. 248 ; Bentb. et Hook. i. 659. 



A small genus, chiefly of tropical and south Africa, but ranging into 

 tropical Asia, and one species reaches Brazil. Three of the Socotran species 

 are endemic, and the fourth is south African.

I have not seen Haworth's description nor his specimens, and the identifica- 

 tion is made on the basis of Harvey's statement. He, however, says, " I am 

 uncertain whether this be Haworth's plant or not." Whether the plant referred 

 to under this name by Harvey be Haworth's species or no, certain is it that

 Haworth's plant be proved to be a different species, it will not invalidate the
