SOME BOTAIflCAL RECOEDS. 195 



customary thorougliiiess, lie located the habitat for the benefit of 

 the would-be finder by telling him to stand immediately opposite 

 Gulval Church, at a place where he could see neither the east nor 

 west sides of the tower, but only the south, and he would be in a 

 direct hne with the grass. I visited the classic spot in September, 

 and was pleased to find the grass flourishing in such quantities 

 as to excite no fear about its extermination by the curious 

 collector. 



Another survival in the same district is Pinguicula grandiflora, 

 an introduction of Dr. Ealf's from the bogs of south-western 

 Ireland. Placed in a couple of spongy marshes west of Penzance, 

 it has increased at a very rapid rate, which is no great matter for 

 surprise when it is remembered that, given suitable conditions, 

 every broken leaf will give rise to a new plant. Dr. Ealf's 

 monument is not in the churchyard, but on those two western 

 bogs. 



In bringing before your notice last year the discovery of 

 Nitella hyalina, I said a careful examination of the Loe had led 

 me to conclude that the plant was probably restricted to a twelve- 

 yard area in Penrose Creek. Acting on the principle that one 

 can never be too careful in expressing an opinion on matters of 

 this kind, I obtained Captain Rogers's consent to make another 

 thorough dredging of the Loe in October. What I said twelve 

 months ago about the distribution of this Nitella is true to-day. 

 If it occurs on British soil other than on the " Nitella bank " in 

 Penrose Creek, no one knows it. 



In the Penryn district the past has been a rich season for 

 that charming little orchid, the Lady's-tresses {Spiranthes 

 autumnalis). In September, in a damp field or two between 

 Penryn and Tremough, Miss S. Imeson, a London botanist, found 

 the grass alive with tens of thousands of the sweet flowers, a 

 record quite unique in the annals of Cornish botany. 



At Ponsanooth we have also had our surprise. For the first 

 time the Upright Penny-royal {Mentha pulegium var. erecta) 

 appeared in the locality, and then not as a straggler but in 

 hundreds. One of the prettiest of mints, it imparted a colour to 

 the spot where it so suddenly sprang up which was attractive a 

 considerable distance away. How it got there is a problem.
