OH CORTICAL FIBR.O-VASCULAR BUNDLES IN SOME 
SPECIES OF LECYTHIDEAE AND B AR.R.IN GT ONIE AE . — 
The following abstract requires a word of prefatory explanation. In 
1883 I noted the peculiarity described in two species of Gustavia 
growing and fruiting in the plant-houses at Cork. Having obtained 
seedlings I made a fairly full study of the anatomy of these plants in 
1884, and kept my results by me in the hope of being able to extend 
them to all the types of the group. I soon found this impossible at 
Cork, and learning that Dr. Lignier 1 (now Professor at Caen, then 
assisting Professor Bertrand at Lille) was at work on the Myrtaceae, 
with ampler opportunities, I handed him over my materials, only 
publishing enough to show my chief results and deductions at the 
Birmingham meeting of the British Association in 1886. Since then 
I have been repeatedly asked for copies of my note, and as Lignier 
does not fully adopt my view as to the origin of the bundles, I have 
thought it advisable, with the kind sanction of the Editors of the 
‘ Annals of Botany/ to disinter it from the Report and reprint it here 
with a few slight emendations all clearly marked off within square 
brackets. 
‘ On Cortical Fibro-vascular bundles in some species of Lecythideae 
and Barringtonieae. — Accessory fibrovascular bundles are usually con- 
nected with abnormalities of vegetation, and probably serve chiefly to 
ensure continuity of the phloem under pressure [the abnormality of 
arborescent sp. of Strychnos is to be regarded as due to reversion 
from climbing ancestors] : hence it is interesting to note their occur- 
rence where this explanation is inadmissible. In Gustavia and Lecythis 
belonging to the sub-order Lecythideae of Myrtaceae there is a com- 
plete system of cortical bundles external to the pericycle, anastomosing 
with the leaf-tracks [of the central cylinder] at the nodes. These
