I have counted the species of domatia-bearing plants in each 

 order in Lundstrom's, Lagerheim's, and this paper, and arranged 

 them in descending order. 



Rubiaceaj, 107; Tiliacese, 40; Bignoniace;©, Oleacese and 

 Lauraceje 16 each; Cupulifera?, 15; Solanefe, 13; Apocynese, 12; 

 Rhamnacea?, Aquifoliaceie and Juglandiacepe, 6 each; Loganiaceaj 

 and Anacardiacete, 4 each; Caprifoliacese, Bixacefe, Meliacese, and 

 Rosacepe, 3 each ; Composita>, Ribesiacese, and Hamamelidepe, 2 

 each ; Asclepidiacene, Sapotacece, Aceracete, Myrtacete, Mag- 

 noliacepe, Ulinaceje, Platanacete, SterculiaceaD, Olacineae, Araliacefe, 

 Viniferae, Saxifrage?e, and Verbenacese, 1 each. From the above 

 it will 1)6 seen that the orders Rubiaceiu and Tiliace?e are far 

 before the others in domatia-bearing species. 



There are, however, included in Dr. Lundl^trom's list some 

 plants which are only doubtfully possessed of these structures, 

 and one or two which certainly are not. To take the latter first. 



Tecoma australis, R.Br. — Dr. Lundstrom says (1, p. 37) — 

 This plant " has 1-3 dimples which are (alwaj^s 1) inhabited, but 



* Remarkable as having branching hairs in the axils.
