234 PLANTS COLLECTED ON MT. RUWENZORI. 
reached the stage of producing a flower-spike and bursting into blossom, it 
has (in comparison to the length of time taken before that stage) reached the 
end of its life; it may perhaps take 12 months for the spike to finish blossoming, 
then the whole plant withers and dries up and stands probably for several years 
longer before it falls and is swallowed up by the moss. In Z. Stuhlmanni the 
leaves do not die and remain on the plant, but all fall off, leaving the stem 
bare except for the green leaves. In L. Deckenii none of the leaves ever fall 
off, and the stem is entirely concealed from sight from the ground up to the 
spike, which is nearly three times as large in circumference as in any of the 
other lobelias, but I think the life of Deckenii is shorter than the others. In 
L. Wollastont some leaves fall off and some remain hanging down, so that it 
usually has a portion of exposed stem, 3 or 4 feet long, below the leaves. In 
L. Giberroa the leaves fall off as in Stuhlmanni. There is another point about 
Deckenti. When we visited Ruwenzori I saw only one Deckenii in blossom, 
there were hundreds of tall dead ones and as many young ones a foot or 
so high ; this looks as if this species had periods of flowering, all the plants 
coming into flower at the same time every few years. 
“L. “Deckenii і is confined to the flat swampy bottoms of the higher valleys and 
does not grow on the sloping hillsides which are covered w ith L. Wollaston? ; 
this latter may be seen by hundreds in all stages of development from 
seedlings to full bloom."

The flowers of L. Livingstonianus are described as purple or white veined 
with purple-white. Dr. Wollaston describes the flowers of the plant 
found on Ruwenzori as yellow. I ean find no other differences.
